To create a certificate request in Cisco UCS Manager, the correct command set involves navigating to the security scope, selecting the appropriate keyring, and then creating the certificate request with the specified IP address and subject name. The commands in option D correctly follow this procedure. The commit-buffer command is used to commit the changes in UCS-A, which is the primary fabric.

References: This process is documented in the Cisco UCS Manager certificate management guidelines, which provide step-by-step instructions on creating certificate requests using the CLI

 When a VLAN is added to a trunk and it does not appear on the vNIC of an associated server, it typically indicates that the vNIC template is not updating as it should to reflect changes. By changing the template type of Trunk-A to an updating template, any changes made to the trunk configuration, such as adding a new VLAN, will be dynamically applied to all vNICs associated with that template. This action will allow the newly added VLAN to be included in the vNIC configuration without the need to manually update each vNIC or recreate the templates.

References := This recommendation aligns with best practices for managing vNIC templates in Cisco UCS environments, where updating templates are used to ensure changes propagate automatically to all associated instances

 The command that completes the EEM script configuration for saving a copy of the running configuration to bootflash on a Cisco Nexus 9000 Series Switch is running-config. This command is used in the EEM applet to specify the source of the configuration file that needs to be copied. The complete command in the EEM applet would be action 1.0 cli command "copy running-config bootflash:/current-config.txt". This command will save the running configuration to a file named current-config.txt in the bootflash when the specified event occurs, which is when a user saves the configuration.

References: For more information on EEM scripts and the copy command on Cisco Nexus 9000 Series Switches, you can refer to the Cisco Data Center Core Technologies documentation and the Cisco NX-OS System Management Configuration Guide

 In a vPC (Virtual Port Channel) configuration, multicast traffic is handled based on the IGMP (Internet Group Management Protocol) and PIM (Protocol Independent Multicast) configurations. When a host sends traffic to a multicast group, the vPC switches determine the forwarding path based on the multicast routing table and the RPF (Reverse Path Forwarding) check.

Option B is correct because when multicast traffic with source address 10.10.10.10 targeting group 239.1.1.1 is received on Po10 Switch1, the switch will perform an RPF check and forward the traffic out of the interfaces that lead to the Rendezvous Point (RP) and the receivers. This ensures that the multicast traffic is efficiently distributed to all receivers that are part of the multicast group. The traffic would be forwarded out on Po1, which is typically connected to the RP, and Po20, which connects to other receivers in the network.

References := For more detailed information on multicast traffic forwarding in a vPC environment, please refer to Cisco’s official documentation on Implementing Cisco Data Center Core Technologies (DCCOR), specifically the sections discussing multicast routing and vPC configurations.

When a Cisco Nexus 9000 series switch encounters a startup configuration corruption, the recovery process involves clearing the current configuration, restarting the device, and then restoring the configuration from a previously saved file. The correct sequence is to first clear the configuration to prevent the corrupted startup configuration from loading upon restart. After restarting the device, the previously saved configuration file should be copied to the running configuration. Finally, to ensure the switch starts with the correct configuration in future restarts, the running configuration should be saved to the startup configuration.

References: The recovery process is detailed in the Cisco community documentation, where it outlines the steps for recovering the configuration in UCS by importing the configuration from a previously saved location

POAP is an automatic provisioning and zero-touch deployment feature that assists device owners in the

initial deployment and configuration of Nexus switches.

The feature works by checking for a local configuration script. If the script has been deleted, the switch has

been reset to factory settings, or this is the first boot-up, the POAP daemon will connect to a preset list of

servers to download an initial configuration file.

To perform this operation, the switch must first obtain an IP address from a local DHCP server. POAP

configuration settings can also be passed through the DHCP response.

Which conditions should be verified, so they need to be TRUE. Like no startup (A) and bootup (B). C means

that it needs to miss a license file and E means it needs to miss an NX-OS image.

NETCONF is the ideal solution for this scenario for the following reasons:

• Standards-based: NETCONF is built upon industry-standard protocols (XML, SSH, TLS) ensuring compatibility and adherence to open standards.
• Secure transport: NETCONF mandates secure transport mechanisms like SSH or TLS for communication between the automation software and managed devices, aligning with security requirements.
• Data Format: NETCONF utilizes XML for data encoding and transport, providing a human-readable and machine-parsable format that is easy to work with.
• Remote Device Automation: NETCONF is designed specifically for remote configuration and management of network devices, making it perfect for the task of automating remote device deployments.

 Option D is the correct configuration set for initializing VXLAN Tunnel End-Point functionality on a Cisco Nexus 9000 Series platform. This option includes the necessary commands to configure the loopback interface, which is used as the source for the VXLAN Network Virtual Endpoint (NVE) interface, and the NVE interface itself, which is essential for VXLAN operation.

References := For a detailed guide on VXLAN configuration on the Cisco Nexus 9000 Series, you can refer to the Cisco Nexus 9000 Series NX-OS VXLAN Configuration Guide, which provides step-by-step instructions and best practices.

The DCNM performance monitoring configuration parameter that must be implemented to achieve the result of triggering events when monitored traffic exceeds the configured percent utilization threshold is the Util% parameter. This parameter allows the administrator to set a utilization threshold as a percentage, which, when exceeded, triggers an event. The requirement to configure a maximum limit of 39860437 bytes directly relates to the statistics collected as a ratio of the total link capacity, which is effectively managed by setting the Util% parameter. This parameter is part of the Performance Manager Configuration Wizard in DCNM, which provides the ability to set up two thresholds that trigger events when the monitored traffic exceeds the percent utilization configured. These thresholds can be set as either Critical or Warning events that are reported on the DCNM-SAN web client Events browser page1.

 A community cloud Infrastructure as a Service (IaaS) deployment model is suitable for several companies that need to operate the same application environment and integrate it with third-party protocols. It allows the development team to have control over the infrastructure, including the operating system, Python interpreter, and libraries

The correct command to configure the source IP address on switch1 for mirroring traffic to a packet sniffer located on switch2 is option B, “monitor erspan origin ip-address 209.165.200.225”. This command sets the origin IP address for the Encapsulated Remote SPAN (ERSPAN) session, which allows traffic from a source port on one switch to be monitored on a destination port on another switch across an IP network.

 The two components that support specific power limits on a Cisco UCS C-Series rack server are the processor and the graphic card. The processor and the graphic card are the two components that consume the most power on a server, and they can be configured to have specific power limits to control the power usage and performance of the server. The power limits can be set using the Cisco Integrated Management Controller (CIMC) web interface or CLI, or using the Cisco UCS Manager if the server is integrated with a Cisco UCS domain. The power limits can be applied to individual processors or graphic cards, or to the entire server. The power limits can help to optimize the power efficiency and thermal management of the server, as well as to prevent power capping or throttling issues. References :=

The question involves an engineer configuring a Cisco MDS 9000 Series Switch and noticing that the name server with IP 192.168.10.11 is missing from the configuration. The correct action to complete the configuration is option C, “Enter yes at step 21 to edit the configuration. Add the line dns-server 192.168.10.11.” This step allows the engineer to modify the initial setup process’s outcome by adding the missing DNS server information directly into the configuration before saving it.

 EPLDs (Electronic Programmable Logic Devices) can be upgraded to enhance hardware functionality or resolve known issues without the need for hardware replacement. The upgrade process is disruptive as it requires the module to power down briefly during the upgrade. However, the system performs EPLD upgrades on one module at a time, minimizing the disruption to traffic through only one module at any given time.

The command in Option D correctly uses a loop to iterate over the range {1…5}, which represents the first five interfaces. The dohost command is used to send commands to the host Cisco Nexus switch from the Guest Shell. The syntax interface eth1/$x and description Server$x within the loop sets the description for each interface eth1/1 to eth1/5 to “Server1” to “Server5” respectively.

Here’s the command from Option D formatted for clarity:

[guestshell@guestshell ~]$ for x in {1..5}; do

dohost "conf t" ;

interface eth1/$x;

description Server$x;

done

This command will configure the description for each of the first five Ethernet interfaces with the respective server number as part of the description.

 NFS uses XDR (External Data Representation) as the communication method for requests between servers and clients. XDR is a standard format for encoding and decoding data that is exchanged between different systems. XDR allows NFS to handle data with different byte orders, word sizes, and data types. XDR is also used by ONC RPC, which is the underlying protocol for NFS. XDR ensures that the data is represented consistently and correctly across different platforms and architectures. References :=

To ensure that the Cisco Nexus 7000 series switches are the primary devices for LACP, the configuration must use the lacp system-priority command to assign a lower priority value to the switches. This command determines which device is the active partner in an LACP negotiation. The lower the priority value, the higher the preference. In option A, the switches have a priority value of 1, which is the lowest possible value and the highest preference. Therefore, option A is the correct configuration to make the switches the primary devices for LACP.

References := The explanation is based on the official Cisco documentation on Configuring Link Aggregation Control Protocol (LACP) 1, specifically the section on Configuring LACP System Priority.

 For a Cisco UCS C-Series Rack Server with PCIe cards, the fan configuration policy should be set to accommodate the additional cooling requirements of these cards. Option C, which sets the fan policy to ‘balanced’, would provide a middle ground between performance and energy efficiency, suitable for a server with additional components such as PCIe cards. This ensures adequate cooling while maintaining energy efficiency.

When configuring the connection between a Cisco MDS 9700 Series Multilayer Director and a Cisco Nexus 5672UP switch, it’s important to consider the following:

• Ensure compatibility: Verify that both devices are running compatible NX-OS versions to ensure they can communicate properly.
• Configure interfaces: Set up the interfaces on both devices with the appropriate type (E, F, or TE), speed, and other relevant settings.
• Establish connectivity: Use the show interface command to confirm that the interfaces are up and the show flogi database command to verify that the Fibre Channel login has been successful.
• Zoning configuration: Configure zoning on the MDS 9700 to control access between devices connected to the fabric.
• VSAN setup: Ensure that the Virtual Storage Area Network (VSAN) is correctly configured and that both switches are part of the same VSAN if required for the topology.

The configuration shown in the exhibit indicates that FCIP (Fibre Channel over IP) is configured with ip-compression mode2 enabled on a Cisco MDS 9000 Series switch. This means compression is performed by using software (Option D), as mode2 refers to software-based compression in FCIP configurations. The other options are not correct based on the configuration. The switch does not attempt to make two TCP connections, as there is no tcp-connections command in the configuration. Compression is not performed by using hardware, as mode1 refers to hardware-based compression in FCIP configurations. Mode2 is not enabled by default, as the default mode for FCIP compression is none. References:

 The command run guestshell is used to access the Guest Shell on Cisco NX-OS devices. Guest Shell is a secure, Linux-based environment that runs as a virtualized application container on the device. It allows network administrators to use Linux utilities and scripts, enhancing automation and monitoring capabilities. In this scenario, using run guestshell would enable the engineer to utilize the tcpdump utility within the container to capture OSPF-related traffic on the switch port1.

To configure multiple EPGs on a single access port in a large Cisco ACI fabric without using VMM integration, the EPGs must be linked to the correct physical domain (Option B) and configured as static ports (Option E). The physical domain is associated with VLAN namespaces and determines the VLAN encapsulation at the interface level. The static ports are used to manually assign the EPGs to the access port. The other options are not required for this configuration. A contract is used to define the communication policy between EPGs, but it is not necessary to create one for this scenario. The EPGs do not link directly to the AAEP, but rather to the interface policy group that is associated with the AAEP. The bridge domains do not need to be configured in legacy mode, which is a mode that allows communication with non-ACI networks. References:

After creating a CA-signed keyring for HTTPS access in Cisco UCS Manager, the next step is to create a trusted point. This action associates the keyring with a certificate and designates the certification authority (CA) that will be recognized as valid for the system

To configure a single Cisco APIC controller for Cisco ACI fabric for the first time, you need to configure the first Cisco APIC controller (B) and register the switches that are discovered through LLDP (D). The initial configuration of the APIC is crucial as it sets up the controller with the necessary settings to manage the ACI fabric. Registering the switches through LLDP allows the APIC to recognize and manage the fabric switches, which is essential for the ACI fabric to function correctly. References: Cisco’s official documentation on setting up an ACI fabric1, and the Cisco APIC Basic Configuration Guide2.

 When storm control is applied to an interface with a zero percent value, it means that the switch will not tolerate any traffic that exceeds the bandwidth of the interfaces during a streaming window. The switch monitors the levels of incoming broadcast, multicast, and unicast traffic over a 1-second interval. When the configured threshold level is reached, further traffic in this category is dropped until the level falls below the threshold.

The requirement for the data center servers to reach services in the cloud and services behind redistributed routes, along with the condition that the exit point toward the internet should only be propagated when there is a dynamically learned default route, necessitates the use of the ‘default-information originate’ OSPF feature. This feature allows the advertisement of the default route in OSPF when it is present in the routing table, which is the case when it is dynamically learned from the upstream router.

References: The ‘default-information originate’ feature is part of OSPF configuration and is used to control the advertisement of default routes in an OSPF environment. This is further explained in the Cisco OSPF Configuration Guide, which details the use of this command to propagate default routes under certain conditions

When converting a Cisco MDS switch to support NPIV mode, it must be enabled globally on all VSANs (B). NPIV allows multiple virtual machines to share a single physical Fibre Channel port, which means that enabling it on all VSANs ensures that this functionality is available across the entire network.

A characteristic of the install all command on the Cisco Nexus series switch is that it automatically checks the image integrity before performing the installation. The install all command is used to install a system image and kickstart image on the switch, as well as to upgrade the BIOS and other firmware components. The install all command performs a series of checks and validations before installing the images, such as verifying the compatibility, checksum, and signature of the images. This ensures that the images are not corrupted or tampered with, and that they match the hardware and software requirements of the switch. The install all command also performs a backup of the current configuration and images, and allows the user to abort the installation process if needed. References :=

When SVR-A in EPG-A/BD-A cannot reach SVR-B in EPG-B/BD-B, it’s crucial to ensure that a contract exists between EPG-A and EPG-B that permits the traffic (Option A). Contracts in Cisco ACI act as a policy framework that dictates the types of traffic allowed between EPGs. Without an appropriate contract, traffic will not be allowed to pass between these entities.

Additionally, verifying that SVR-B is learned as an endpoint in EPG-B from Node-112 (Option C) is essential. Endpoint learning within ACI is a process where the leaf switch learns about the endpoints connected to it. If Node-112 has not learned SVR-B as an endpoint, it will not be able to forward traffic to it, resulting in connectivity issues.

References: = For more information on contracts and endpoint learning, refer to the Cisco ACI documentation on the Cisco official website. Specifically, look into sections detailing ACI contracts and endpoint learning processes.

FCoE (Fibre Channel over Ethernet) is a technology that allows Fibre Channel traffic to be encapsulated and transported over Ethernet networks. FCoE requires the use of FCFs (Fibre Channel Forwarders), which are devices that act as bridges between the FCoE and Fibre Channel domains. FCFs can be configured with a priority value that determines their preference for connecting to CNAs (Converged Network Adapters), which are devices that support both Ethernet and Fibre Channel protocols. The priority value ranges from 0 to 1024, with 0 being the lowest and 1024 being the highest. To configure an MDS switch as the best switch to connect by the CNAs in the fabric, the fcoe fcf-priority 1024 command should be applied. This gives the switch the highest priority and makes it the most preferred FCF for the CNAs.

 The System Configuration backup type in Cisco UCS Manager is specifically designed to back up system settings such as user names, roles, and locales. This XML file does not include the actual data on the servers but captures all the system configuration settings, which can be imported to the original fabric interconnect or to a different one. However, it cannot be used for a system restore.

References: Cisco UCS Manager Administration Management Guide

The ‘Full State’ backup type in Cisco UCS Manager is designed to capture a snapshot of the entire system, which includes all configuration settings, system logs, and the operating system. This comprehensive backup can be used to fully restore the system in the event of a disaster recovery scenario. The ‘Full State’ backup is the only option that provides a complete system snapshot, making it the ideal choice for disaster recovery purposes.

References: The information regarding backup types and their purposes can be found in the Cisco Data Center Core Technologies source book, specifically in the section discussing system maintenance and backups within the Cisco UCS Manager platform.

The correct command set is Option C, which includes the command fcdomain fcid persistent vsan 120. This command ensures that the Fibre Channel IDs (fcid) are saved across reboots for VSAN 120, meeting the requirement for persistent Fibre Channel IDs. The other commands in Option C are used to set the WWN and fcid as per the given requirements.

You can use firmware packages in service profiles to upgrade the server and adapter firmware, including the BIOS on the server, by defining a host firmware policy and including it in the service profile associated with a server.

Options B and D are the correct components that should be checked when a Cisco Nexus 9000 Series Switch fails to boot using POAP (Power On Auto Provisioning). POAP requires a DHCP server to bootstrap IP information for the switch, and a TFTP server that contains the configuration script and the image file for the switch. The other options are either irrelevant or incorrect for POAP. References:

One of the benefits of independent resource scaling in Cisco HyperFlex hybrid architecture is the flexible expansion of compute, caching, and capacity. This allows for the addition of resources in the required ratios without being constrained by the limitations of traditional converged infrastructure3.

The Device Connector Access Mode should be configured as ‘Allow Control’ within the Cisco UCS Manager to enable full configuration capabilities. Claiming the device on Intersight as ‘UCSM Managed Mode’ ensures that the device can be managed through both the Cisco UCS Manager and the Intersight platform. This configuration aligns with the best practices for setting up Cisco UCS domains for integration with Intersight, allowing for seamless monitoring and management while maintaining security and control12.

References := For further details on the configuration process and best practices, you can refer to the Cisco Intersight Managed Mode Configuration Guide and other official Cisco documentation related to UCS domain profiles and Intersight integration

 SSH (Secure Shell) is the protocol that allows secure remote login from one computer to another. It provides strong authentication and secure communications over unsecured channels. This protocol is preferred for automated onboarding of devices like Cisco Nexus 9000 Series Switches because it supports strong encryption and credential-based authentication, which aligns with the requirement for minimal connection methods and security. SSH is commonly used in network automation for secure command execution and file transfers1.

References := For more information on configuring Cisco Nexus 9000 Series Switches for automation and integration with systems like Cisco UCS Director, you can refer to the Cisco Nexus 9000 Series NX-OS Programmability Guide, which details the supported manageability features and advanced automation capabilities, including Power On Auto Provisioning (POAP) and integration with automation frameworks

Network-attached storage (NAS) is a solution that provides remote and direct file-level access to users and systems. NAS devices are connected to the network and offer shared storage space for files and data. Users and systems can access the files using standard protocols such as NFS or SMB. NAS devices can also offer features such as backup, replication, and security.

When implementing NPV mode on a Cisco MDS 9000 Series Switch, it is crucial to ensure that NPIV is enabled on the upstream switch. NPV mode allows the switch to pass traffic between end devices and the core without consuming a domain ID. For NPV to function correctly, the upstream switch must support NPIV, which allows multiple virtual machines to share a single physical port without conflicts. References := Switch Configuration - Configuring N Port Virtualization

Placing all EPGs in the preferred group within a VRF allows for communication between them without the need for additional contracts. This is because the preferred group feature in Cisco ACI allows EPGs within the same VRF to communicate with each other by default, bypassing the need to provide and consume contracts1. This simplifies the configuration process when new EPGs and bridge domains are added, as they inherit this communication capability by being part of the preferred group1.

References := For more information on the implementation of VRFs and the use of the preferred group feature in Cisco ACI, you can refer to the Cisco documentation on “Use vzAny to Automatically Apply Communication Rules to all EPGs in a VRF” and other related resources1. These documents provide detailed guidance on how to configure VRFs and EPGs to achieve seamless communication within the network infrastructure.

When configuring traffic capture to investigate issues such as buffering problems and packet drops, it’s important to consider where to place the capture points. Typically, you would configure a SPAN (Switched Port Analyzer) or RSPAN (Remote SPAN) session to mirror the traffic from the affected areas to a monitoring device. The configuration would involve:

• Identifying the source ports or VLANs where the issues are observed.
• Specifying a destination port connected to a network analyzer like Wireshark.
• Ensuring the destination port is not used for regular network traffic.

For example, a basic SPAN session configuration might look like this:

monitor session [session_number] source interface [interface_id]

monitor session [session_number] destination interface [destination_interface_id]

To meet the requirements for configuring Cisco NX-OS REST API on a Cisco 9000 Series Switch, the correct configuration set is option B. This set of commands enables the NX-API feature, sets the NX-API to listen for HTTP traffic on TCP port 83, uploads the HTTPS certificate, and then enables the certificate. The inclusion of the nxapi certificate enable command is crucial as it activates the uploaded certificate, which is necessary for establishing secure HTTPS connections.

References: The configuration guidelines are based on the Cisco Nexus 9000 Series NX-OS Programmability Guide, which details the steps for enabling and configuring NX-API REST and DME database on Cisco Nexus switches1.

To use SaaS to manage Cisco computing, you need to have a Cisco Intersight account and a device/claim ID for each device that you want to manage. Cisco Intersight is a cloud-based platform that provides unified management, automation, and analytics for Cisco data center products. A device/claim ID is a unique identifier that is generated when you register a device with Cisco Intersight. You can use the device/claim ID to claim the device and add it to your Intersight account. Once you claim the device, you can monitor, configure, and troubleshoot it from the Intersight dashboard. References: For more information on how to use SaaS to manage Cisco computing, please refer to the following resources:

 Python is a versatile scripting language that supports the rapid creation and removal of logical containers, the development of custom modules and data structures, and is extensible with a wide range of external libraries and modules. It also allows for on-demand execution, making it ideal for automating tasks in Cisco ACI Fabric

 To automate the provisioning of Cisco ACI objects using Terraform while ensuring that APIC counts the authentication login requests against the threshold to avoid a DOS attack, signature-based authentication should be used. This method involves obtaining an authentication token from Cisco APIC, which will use the token to authenticate. However, APIC counts these authentication requests and applies a threshold to prevent DOS attacks. After too many attempts, the user ID and password authentication method may fail as the threshold is exceeded. To circumvent this issue, signature-based authentication is recommended, where a signature is calculated using a private key and passed with the request. This signature is then used to authenticate the user without being counted against the threshold, thus avoiding the risk of exceeding it and failing authentication.

References: The information is based on the Terraform documentation provided by CiscoDevNet

To deploy a Cisco UCS C-Series Server with a single VIC 1455 integrated into a Cisco UCS Manager cluster without fabric extenders, the system should be reset to factory default settings using Cisco IMC. After the reset, VIC ports 1 and 3 should be attached to the Fabric Interconnects. This process ensures that the server is recognized by the UCS Manager and can be managed accordingly. The VIC 1455 supports multiple Ethernet and Fiber Channel over Ethernet speeds, making it suitable for direct connection to Fabric Interconnects1.

The attribute that must be selected to implement microsegmentation of endpoints within the same IP subnet using a network-based attribute that allows IP subnet independence is the Tag attribute. The Tag attribute is a user-defined attribute that can be assigned to endpoints based on any criteria, such as location, function, or security level. The Tag attribute can be used to create microsegmentation policies in ACI, which define the rules for communication between endpoints within the same or different bridge domains. The Tag attribute enables IP subnet independence, which means that the microsegmentation policies are not tied to the IP subnet of the endpoints, and can be applied across different subnets or even different fabrics. The Tag attribute also simplifies the management and scalability of microsegmentation policies, as it does not require the use of IP addresses or MAC addresses to identify endpoints. References :=

Enabling the vPC peer gateway feature on the vPC devices allows them to act as the active gateway for packets that are addressed to the router MAC address of the vPC peer. This capability allows both vPC peers to forward traffic and eliminates traffic disruption when one of them goes down, ensuring high availability in network operations.

References: = For more detailed information, you can refer to the Cisco Nexus 9000 Series NX-OS High Availability and Redundancy Guide, which provides guidelines on configuring vPC peer gateway features for enhanced network stability and availability.

Before upgrading the infrastructure and firmware of multiple UCS blades, it is important to verify if the bootflash on the fabric interconnects in the Cisco UCS has at least 10% available space © and to get Full State and All Configuration backup files before beginning the upgrade (E). Ensuring sufficient bootflash space is necessary for the upgrade process to proceed without storage issues. Backing up the current state and configuration provides a recovery point in case the upgrade encounters problems. References: Cisco’s guidelines on firmware upgrades3 and community discussions on UCS firmware updates4.

The ‘best-effort’ command is used when implementing a configuration checkpoint on a Cisco Nexus 9000 Series Switch to ensure that the process skips any existing vPC configuration errors and completes even if there are other configuration errors. This command is suitable for scenarios where it’s critical to proceed with the checkpoint despite errors, allowing the engineer to create a rollback point and address issues without disrupting the entire process.

Cisco IMC software policy is used to install new Cisco IMC software on a server. This policy allows the administrator to specify the desired Cisco IMC software version and the schedule for the installation. The other policies are used to manage different aspects of the server firmware, such as the host firmware, the hypervisor firmware, and the BIOS software. References:

The statement that applies to a Cisco Nexus 5600 Series switch when performing a rollback is that errors are skipped when an atomic rollback type is triggered. An atomic rollback is a type of rollback that implements the checkpoint configuration only if no errors occur during the process. If any errors are encountered, the rollback is aborted and the running configuration is restored to its previous state. This ensures that the switch does not end up in a partially configured or inconsistent state. The other statements are not true because:

• A user who is assigned to the network-operator user role cannot perform a rollback. The network-operator user role has read-only access to the switch and cannot modify the configuration. To perform a rollback, the user must have the network-admin or vdc-admin user role.
• The configuration rollback functionality is not disabled when FCoE is enabled. The rollback feature is supported on all Cisco Nexus 5600 Series switches regardless of the FCoE configuration. However, some FCoE-related commands may not be rolled back due to dependencies or conflicts with other features.
• A system checkpoint is not generated automatically when the running configuration is saved to NVRAM. A system checkpoint is a predefined checkpoint that contains the last saved configuration of the switch. A system checkpoint is created or updated only when the user explicitly saves the running configuration to the startup configuration using the copy running-config startup-config command or its alias, copy run start. References: For more details on how to configure and use the rollback feature on a Cisco Nexus 5600 Series switch, please refer to the following resources:

 The configuration in Cisco UCS Manager needs to specify the source of the traffic for the SPAN session. Since the requirement is to monitor the traffic from VSAN 11, selecting VSAN 11 as the source will direct the traffic to the monitoring session. This is consistent with the SPAN session’s purpose, which is to create a copy of the traffic for analysis or monitoring.

References := For more information on configuring SPAN sessions in Cisco UCS Manager, you can refer to the Cisco Data Center Core Technologies study materials and official documentation, which provide guidelines on setting up traffic monitoring solutions within a Cisco data center environment. These resources will offer detailed instructions and best practices for implementing SPAN sessions to monitor VSAN traffic.

 To configure a Fibre Channel device alias named TEST for a device attached to port fc1/9 on a Cisco Nexus Series Switch, the correct command set is found in Option A. The commands should be entered in configuration mode, starting with accessing the device-alias database, creating the device-alias named TEST with the specified pwwn, and committing the changes to the database123.

References := The process for configuring a Fibre Channel device alias on a Cisco Nexus Series Switch is detailed in the Cisco Nexus 9000 Series NX-OS SAN Switching Configuration Guide and other Cisco documentation related to SAN switching and device aliases

The command that reduces the amount of time it takes to complete the ISSU on a Cisco Nexus 7000 series switch that has dual supervisor modules and two I/O modules is install all kickstart systemparallel. This command performs a parallel upgrade of the kickstart and system images on all modules, which reduces the downtime and speeds up the ISSU process. The other commands (install all epld bootflash: and install all kickstartsystem) do not perform a parallel upgrade and take longer to complete the ISSU. References: For more information on how to perform an ISSU on a Cisco Nexus 7000 series switch, please refer to the following resources:

• Cisco Nexus 7000 Series NX-OS Software Upgrade and Downgrade Guide
• Cisco Nexus 7000 Series NX-OS ISSU Upgrade Guide

In a multihomed OTV network, it is essential to configure the remote OTV AEDs (Authoritative Edge Devices) to use both the primary and secondary adjacency servers for redundancy and resiliency. The correct configuration, Option D, includes the otv use-adjacency-server command with both IP addresses of the primary and secondary servers followed by unicast-only, which indicates that the AEDs should use unicast connections to the adjacency servers instead of multicast.

References := This configuration aligns with best practices for setting up OTV networks as described in Cisco’s Data Center Core Technologies documentation. For a more comprehensive understanding, refer to the study materials related to OTV configurations in the Cisco Data Center Core Technologies (DCCOR) course.

The Bash script is designed to loop through the available namespaces and output all registered interfaces within the Cisco NX-OS Guest Shell. The correct code snippet to complete the script is option C, ifconfig "$ns". This command will display the network configuration for each namespace, allowing the engineer to view all registered interfaces.

References: The use of ifconfig in conjunction with namespace variables is a common practice in network scripting to retrieve interface information. For more detailed information on scripting in Cisco NX-OS, you can refer to the Cisco Nexus 9000 Series NX-OS Programmability Guide.

The correct configuration to capture traffic only from the server with the IP address of 198.19.1.19/24 is option C. This configuration uses an IP access list to match packets from the specific IP address with a subnet mask of 255.255.255.255, which indicates a single host. The monitor session command is then used to apply this access list to a SPAN session, ensuring that only traffic from the specified server is captured.

The In-Service Software Upgrade (ISSU) feature on Cisco Nexus 9000 Series Switches supports nondisruptive upgrades via nonstop forwarding. This allows the switch to continue forwarding traffic while the system software is being upgraded, thereby minimizing downtime and maintaining continuous network service

 To add a Cisco HyperFlex data platform to the Cisco Intersight management portal, two components are required for Intersight to claim the Cisco HyperFlex data platform: the device claim code and the device serial number. The device claim code is a unique identifier that is generated by the Cisco HyperFlex installer and is used to register the device with Intersight. The device serial number is the serial number of the Cisco HyperFlex controller node and is used to verify the device ownership and entitlement3.

References := 3: [Cisco HyperFlex Systems Installation Guide for Cisco Intersight, Release 4.0] : [Cisco Intersight Device Connector Installation and Reference Guide]

 To configure an application profile using REST API, the engineer needs to first authenticate with the APIC using the POST method to the aaaLogin URI. This will return a token that can be used for subsequent requests. The error message indicates that the token is missing or expired, so the engineer needs to perform the POST to aaaLogin method again before configuring the application profile. References := [Cisco APIC REST API Configuration Guide]

To implement traffic monitoring for a server vNIC with fabric failover enabled, ensuring that traffic is sent to an analyzer even during a fabric interconnect failure, the correct configuration is to create two traffic monitoring sessions with different names, one per fabric, and connect an analyzer on each FI as the destination for the monitoring session local to the FI. This setup allows continuous monitoring because if one fabric interconnect fails, the other can still send traffic to its connected analyzer2.

References := Cisco Community Discussion on Understanding Fabric Failure and Failover in UCS

 The device-alias confirm-commit command is used in Cisco MDS 9000 Series Switches to ensure that changes made to device aliases are confirmed before being committed to the database. This command prompts the user for confirmation and displays the pending changes explicitly on the console, which aligns with the requirements stated in the question.

References: For more detailed information, you would typically refer to the Cisco Data Center Core Technologies study guide or the official Cisco documentation for the MDS 9000 Series.

 To establish adjacency to the remote peer by using multicast, the engineer needs to configure the otv data-group command with a multicast address range that is unique for each site. This command specifies the multicast group that is used to send and receive OTV data traffic. To enable OTV advertisements for VLAN 100 to the other site, the engineer needs to configure the otv extend-vlan command with the VLAN number. This command specifies which VLANs are extended across the overlay network. References:

The correct command to restore the running configuration on a Cisco Nexus 5000 Series Switch to an existing snapshot called “stable1” is found in Option C. The command rollback checkpoint stable1 best-effort running-config best-effort ensures that the restore procedure will proceed only if no errors occur, which aligns with the requirement stated in the question. The “best-effort” parameter is crucial as it indicates that the rollback should only proceed if it can be completed without any errors.

 ARP suppression is a feature used in VXLAN/EVPN environments to optimize ARP responses and reduce unnecessary ARP broadcasts across the fabric. When ARP suppression is enabled, the local VTEP (VXLAN Tunnel Endpoint) can respond to ARP requests for known IP-to-MAC address bindings, which are learned via the BGP EVPN control plane. This prevents the need for ARP broadcasts to be sent across the entire VXLAN fabric, thus optimizing the ARP response mechanism and reducing broadcast traffic1.

• Cisco Programmable Fabric with VXLAN BGP EVPN Configuration Guide2.
• Community discussions on ARP suppression in VXLAN/EVPN

The roles required to modify system logs, faults, and power management settings, as well as view access to all other configurations in the UCS domain, are typically those that provide broad administrative capabilities. The Operations role allows for the modification of operational aspects such as logs and power management, while the Administrator role provides full access to all configurations and settings within the UCS domain1.

References: = For more detailed information on user roles and permissions in Cisco UCS, you can refer to the Cisco UCS Manager Administration Management Guide2 and other official Cisco documentation1.

 To meet the high-security standards, the engineer should configure port security and fabric binding on VSAN 50. Port security prevents unauthorized devices from logging into the fabric by automatically learning and securing the World Wide Port Names (WWPNs) of devices connected to the switch ports. Fabric binding allows only authorized switches to join the fabric by creating a list of switch WWNs that are permitted to join a specific VSAN.

The data interchange format presented in the output is JSON (JavaScript Object Notation), which is commonly used for transmitting data in web applications and for configuration files. It is easily readable both by humans and machines.

For detailed explanations and references, it’s best to consult the official Cisco documentation or the Cisco Data Center Core Technologies study guide.

In the context of Cisco ACI (Application Centric Infrastructure), TEP (Tunnel Endpoint) addresses are used for encapsulating and forwarding traffic within the fabric. The next hop addresses mentioned in options A and D are indicative of TEP addresses, which are typically assigned to border leaf switches within the ACI fabric. These border leaf switches are responsible for routing traffic between the ACI fabric and external networks.

• Option A is correct because the next hop 10.0.1.14 for the route 172.16.99.0/24 is consistent with the TEP address format used in ACI, suggesting it is the TEP address of a border leaf.
• Option D is also correct as the next hop 10.1.168.95 for the route 172.16.100.0/24 follows the TEP address pattern, indicating it is the TEP address of another border leaf in ACI.

 A Cisco All-Flash HyperFlex solution requires two solid state drives (SSDs) for the local storage configuration of the operating system and persistent logging. The SSDs are used to store the hypervisor, the HyperFlex controller VM, and the system logs. The SSDs also provide high performance and reliability for the system operations. The SSDs are configured in a RAID 1 mirror mode, which provides redundancy and fault tolerance. The SSDs are separate from the data storage drives, which are also SSDs in an All-Flash HyperFlex solution. References :=

A full state configuration backup in Cisco UCS Manager includes a snapshot of the entire system, which is stored as a binary file. This backup type is ideal for disaster recovery as it can restore or rebuild the configuration on the original fabric interconnect or recreate the configuration on a different fabric interconnect. It is important to note that this backup type cannot be used for an import but is specifically designed for system restoration.

References:

• Cisco’s official documentation on “Backing Up and Restoring the Configuration” provides a detailed guide on the backup types and procedures within Cisco UCS Manager1.
• The “Cisco UCS Manager Administration Management Guide 4.2” further elaborates on backup operations, considerations, and the system restore process

In Cisco ACI, a virtual Port Channel (vPC) allows links that are physically connected to two different ACI leaf nodes to appear as a single port channel to a third device. When configuring vPCs in ACI, you do not need to create multiple interface policy groups for each vPC. Instead, you create a single vPC interface policy group that can be applied to multiple vPCs. This is because the fabric itself serves as the multi-chassis trunk (MCT), and peer reachability is managed through the fabric, not through physical peer-links. Therefore, for the scenario described, where two vPCs are created from leaf switches A and B, only one vPC interface policy group is required.

References := The information is based on the best practices from the Cisco guide on Virtual Port Channel (vPC) in ACI1 and the Cisco ACI fabric access policies configuration guide

When you run the install commit  command on a Cisco Nexus 9000 Series Switch, it schedules the new package to be used after the next reboot of the switch. This means that the current running configuration isn’t immediately affected by the new package, but it will be incorporated once the switch is restarted.

To meet the requirements of performing a backup and restore of the Cisco Nexus 5000 Series Switch configuration using UDP as the only protocol, the network engineer must follow these steps:

• Perform a startup-config backup to a TFTP server. The startup-config file contains the configuration that is applied when the switch boots up. To backup this file to a TFTP server, the engineer can use the copy startup-config tftp: command, and specify the IP address or hostname of the TFTP server and the destination filename. For example:

switch# copy startup-config tftp: Enter hostname for the tftp server: 10.10.10.10 Enter destination filename: backup-config

• Copy backup-config from the backup server to the running-config file. The running-config file contains the configuration that is currently active on the switch. To restore this file from the backup-config file on the TFTP server, the engineer can use the copy tftp: running-config command, and specify the IP address or hostname of the TFTP server and the source filename. For example:

switch# copy tftp: running-config Enter hostname for the tftp server: 10.10.10.10 Enter source filename: backup-config

These steps will allow the engineer to backup and restore the switch configuration using UDP as the only protocol, as TFTP is a UDP-based protocol. The backup-config file can be used when the current working configuration of the switch gets corrupted, as required by the goal. References :=

The configuration must ensure that the SPAN session captures traffic from the file server’s VSAN to the destination interface connected to the FC analyzer. The commands provided in the exhibit show the setup of a SPAN session with the destination interface as port-channel 2 and the source interface as VSAN 100, which is likely the VSAN associated with the file server.

These resources provide comprehensive insights into deploying, securing, operating, and maintaining Cisco data center infrastructure, including the Cisco MDS Switches.

 To block traffic between a subset of endpoints in an EPG based on specific VM attributes and the rest of the VMs in that EPG, the correct set of actions would involve setting “Allow Microsegmentation” under the EPG VMM Domain Association to “True” and setting “Intra-EPG Isolation” to “Enforced” for both the EPG and the uSeg EPG. This configuration ensures that microsegmentation is allowed and that intra-EPG isolation is enforced, effectively blocking the specified traffic.

 In the context of Bash scripting for system automation, the killproc command is often used to stop a process. The correct option to complete the script for a Chef Client reload would involve sending a HUP (hang-up) signal to the Chef Client process, which is typically done to cause the process to reload its configuration without stopping the service. The command killproc -p $pidfile $exec --HUP would send the HUP signal to the process identified by the pidfile, which is the expected behavior for a Chef Client reload on a system reset.

References := For a detailed explanation and official documentation, the Cisco Data Center Core Technologies source book or study guide should be consulted, as well as the official Chef documentation which provides information on system and service management commands.

Applying a control plane service policy with a rate-limiting feature allows the engineer to match all ICMP traffic and set a threshold for it. Traffic that exceeds this threshold can be dropped, thus mitigating the risk of ICMP-based DoS attacks while allowing legitimate ICMP traffic to pass through. This method ensures that the current ICMP traffic is not affected as long as it does not exceed the configured rate limit12.

References := For detailed steps on configuring rate limits and control plane policing on Cisco Nexus 9000 Series Switches, you can refer to the Cisco Nexus 9000 Series NX-OS Security Configuration Guide12. This guide provides comprehensive information on securing your network infrastructure and protecting against various types of attacks, including DoS attacks. It also covers the configuration of security features like rate limits and control plane policies to ensure network stability and security

In OSPF, the router with the highest priority on a network becomes the Designated Router (DR), responsible for generating LSAs for the network. By default, all Cisco routers have an OSPF priority of 1. To ensure that SW2 becomes the DR and controls the LSA floods, its priority needs to be the highest in the OSPFv2 area. The command in option A sets the OSPF priority to the maximum value of 255, which will make SW2 the most likely candidate to be elected as the DR, provided that no other router has a higher priority or a higher router ID if priorities are equal.

References := This explanation is based on the OSPF election process as described in Cisco’s OSPF design guide and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials. For detailed information, please refer to these resources.

 Configuring an ERSPAN session between N5K-1 and N5K-2 is the appropriate action to accomplish the goal of collecting traffic, including payload, for further investigation. ERSPAN will mirror the traffic from the source to the destination over an IP network, allowing the network engineer to capture and analyze the traffic at the headquarters.

References: = For more information on how to configure ERSPAN sessions on Cisco devices, you can refer to the Cisco Nexus 5000 Series NX-OS Software Configuration Guide

The command checkpoint file before_maintenance is used to create a checkpoint of the current running configuration with the specified file name. The command rollback running-config file before_maintenance atomic ensures that the rollback of the checkpoint to the running configuration only occurs if there are no errors during the process. This is essential for maintaining the stability of the switch during maintenance operations.

 Cisco UCS Director is the appropriate solution for orchestrating the configuration of storage arrays, firewalls, and Cisco ACI networking. It supports open automation through various APIs and offers a service catalog that allows users to manage and deploy services across multiple domains, including compute, storage, networking, and virtualization.

The network administrator role in Cisco UCS Manager is designed to allow configuration of network-related settings, which includes vHBAs, vNICs, and server port types. This role provides the necessary privileges to manage these components

The statement that is true about the behavior of multiple roles applied to a user on the Cisco MDS 9000 Series Switch is that access to a command takes priority over being denied access to a command. This means that if a user has multiple roles assigned and one of the roles grants access to a command while another role denies access to the same command, the user will be able to execute the command. The access permission overrides the deny permission in case of a conflict. The other statements are not true because:

• Any commands that have conflicting settings between roles are not denied. As explained above, the access permission prevails over the deny permission in case of a conflict.
• The first role assigned does not take precedence over subsequent roles. The order of role assignment does not affect the command authorization. All roles assigned to a user are evaluated together and the most permissive setting is applied.
• The last role assigned does not take precedence over previous roles. The order of role assignment does not affect the command authorization. All roles assigned to a user are evaluated together and the most permissive setting is applied. References: For more information on how to configure and manage roles on the Cisco MDS 9000 Series Switch, please refer to the following resources:

A Multi-Site Orchestrator deployment requires two orchestrators to be deployed, one in each of the two main data center sites. The Multi-Site Orchestrator is a software component that enables the management and orchestration of multiple Cisco Application Centric Infrastructure (ACI) fabrics that are geographically distributed across different locations. The Multi-Site Orchestrator provides a single pane of glass for configuring, monitoring, and troubleshooting the ACI fabrics, as well as synchronizing policies and tenants across the sites. The Multi-Site Orchestrator also supports disaster recovery and high availability scenarios by allowing the replication of data and services between the sites. The Multi-Site Orchestrator deployment consists of two orchestrators that form a cluster and communicate with each other using a secure channel. Each orchestrator is connected to one or more ACI fabrics in the same site, and acts as a proxy for the other orchestrator to access the ACI fabrics in the remote site. The orchestrators use a leader-election algorithm to determine which one is the active orchestrator and which one is the standby orchestrator. The active orchestrator handles all the requests from the users and the applications, while the standby orchestrator monitors the health and status of the active orchestrator and takes over in case of a failure. The orchestrators also perform periodic data synchronization to ensure consistency and reliability. References :=

The benefit of adding Cisco HyperFlex Hardware Acceleration Cards to a HyperFlex deployment is increased compression efficiency. These cards are PCIe devices that offload the compression and decompression operations from the CPU, resulting in higher performance and lower latency for most storage workloads. The cards also reduce the CPU utilization and power consumption of the HyperFlex nodes, enabling more resources for other applications. The other options (offline encryption acceleration, increased network throughput, and GPU acceleration) are not benefits of the HyperFlex Hardware Acceleration Cards. References: For more information on the HyperFlex Hardware Acceleration Cards, please refer to the following resources:

 To install an operating system on a LUN provided by the Fibre Channel storage array, the engineer needs to configure the boot policy to include a SAN Boot Target with a WWPN (World Wide Port Name). This ensures that the server can communicate with the specific LUN on the storage array during the boot process. Additionally, adding Local CD/DVD and SAN Boot in the boot policy provides flexibility for installation sources, ensuring that both local and networked storage options are available during boot. References := Cisco Data Center Core Technologies source documents or study guide

 The correct code snippet to ensure that the Cisco NX-OS scheduler runs every day at 3:00 a.m. is “time daily 3:00”. This command configures the scheduler to execute the specified job daily at the given time, without the need for a ‘start’ keyword, which is not required in the syntax for daily repetitive tasks.

References: This explanation is based on the Cisco NX-OS documentation, which provides guidelines on how to schedule tasks using the NX-OS scheduler feature. The documentation is part of the Cisco Data Center Core Technologies study materials.

A logical configuration backup of a Cisco UCS Manager database is a file that contains all of the configurations that are stored in the Cisco UCS Manager database, such as policies, pools, service profiles, templates, and firmware versions. The file has an extension .tgz and can be created and restored using the Cisco UCS Manager GUI or CLI. A logical configuration backup also contains the configuration organizations and locales, which are logical entities that group and isolate resources within a Cisco UCS domain. Organizations and locales can be used to delegate administrative tasks and privileges to different users or groups. The other options (AAA and RBAC configurations, VLAN and VSAN configurations) are not part of a logical configuration backup, but rather a full state backup, which is a different type of backup that includes the operational state and statistics of the Cisco UCS domain. References: For more information on how to create and restore a logical configuration backup of a Cisco UCS Manager database, please refer to the following resources:

When connecting a Cisco UCS Fabric Interconnect (FI) directly to an external storage array using a Fibre Channel (FC) storage port, it is essential to configure the FI in FC switch mode. This mode allows the FI to manage FC traffic and zoning, which is necessary when bypassing an upstream SAN switch. Additionally, creating the required Virtual Storage Area Network (VSAN) within the SAN cloud is crucial for isolating and managing the traffic between the FI and the storage array. The VSAN provides a unique identifier that enables the direct connection and communication between these devices.

References: The configuration steps for direct attachment of a storage array to a Cisco UCS FI are detailed in Cisco’s official documentation and support forums1. Specifically, the process involves setting the FI in FC switch mode and creating the necessary VSAN for the connection1. These references provide guidance based on Cisco’s recommended practices for such configurations.

Port security on Cisco MDS 9000 series Switches is a feature that allows administrators to restrict access to the switch ports to specific devices. When port security is enabled, it does not automatically add currently logged-in devices to the device database; they must be added manually. This ensures that only authorized devices can access the network, enhancing the security of the SAN environment.

References: The Cisco MDS 9000 Series Security Configuration Guide provides detailed information on the configuration and behavior of port security, including the requirement for manual addition of devices to the database

Option A is the correct command set to use the python module in the guest shell of the Cisco Nexus 9000 Series switch to shutdown port Ethernet 1/4.

 Option D is the correct configuration to enable the Cisco UCS Manager to manage a Cisco UCS C-Series server by using a single cable for management and data traffic. The commands enter the server scope, then the cimc scope, then the mgmt-conn scope with the sideband option, which enables the management connection through the sideband interface. Then, the mgmt-conn-state is set to enabled and the changes are committed to the buffer. References:

 This type of backup includes information about VLANs, VSANs, and other policies and is in XML format, which is human-readable. Although the question specifies the use of UDP, none of the options provided use UDP as they are all TCP-based protocols; however, TFTP is often confused with being UDP-based because it is a lightweight protoco

To add a new VRF (DC DC) that allows communication of network prefixes between PE1 and PE2 using MP-BGP and EVPN, the engineer should choose Option B and Option E. These options likely include the necessary configurations for route distinguishers and route targets that facilitate the import and export of routes between the VRF instances on different PE routers1

Option A is the correct order of reloading components during the process of upgrading the EPLDs of the fabric modules for a Cisco MDS director-class switch. The EPLD upgrade is performed on one fabric module at a time, and the fabric module is reloaded after the upgrade. The other fabric modules and the switching platform are not reloaded during the process. References:

When using VMware vMotion to migrate a Cisco WSA virtual appliance from one physical host to another, it is essential that both physical hosts have access to the same network configurations. This includes the same defined networks to which the interfaces on the virtual appliance are mapped. This requirement ensures that the virtual appliance retains its network connectivity and continues to function correctly after the migration1.

References := For more information on the requirements and process of migrating a Cisco WSA virtual appliance using VMware vMotion, you can refer to the Cisco Secure Email and Web Virtual Appliance Installation Guide1.

To meet the deployment requirements for implementing VSANs on a Cisco MDS 9000 Series Switch, the correct steps are to create VSAN 10 in the VSAN database and bind it to the interface fc1/1. This assigns the host on port fc1/1 to VSAN 10. Additionally, enabling VSAN trunking on the Inter-Switch Link (ISL) and allowing VSAN 10 on the ISL ensures that the port channel 10 can pass multiple VSANs, including VSAN 10. This configuration allows for the segregation of traffic and maintains the isolation of different VSANs while still permitting communication across the shared physical infrastructure12.

• The “Cisco MDS 9000 Series Fabric Configuration Guide” further elaborates on managing VSANs and their associated interfaces

To configure a SPAN session on a Cisco Nexus 5600 Series Switch that monitors ingress traffic on interface Ethernet 1/3 without impacting the traffic analyzer on Ethernet 1/5, you would typically use the monitor session command to create a new session, specify the source interface with the source keyword, and the destination interface with the destination keyword. Additionally, you would apply a rate limit to the session to adhere to the traffic budget of 1 Gbps.

 To provision a new uplink and increase the available bandwidth for the NPV enabled switch, the commands in Option A should be used. These commands will configure the additional uplink to the NPIV switch, thus addressing the bandwidth contention issues experienced by the servers.

The Firmware Auto Sync Server policy in Cisco UCS Manager allows administrators to set when and how firmware versions on recently discovered servers should be upgraded. The policy options include ‘User Acknowledge’, which requires an administrator’s acknowledgment to initiate the firmware upgrade, and ‘No Action’, which means no firmware upgrade will be initiated on the server. These settings ensure that firmware upgrades are controlled and do not occur without the necessary administrative oversight.

Upgrading the EPLD on a Cisco Nexus switch is a disruptive process that requires the switch to reboot multiple times. Each EPLD device on the switch must be upgraded individually, and the switch must reboot to initialize the new EPLD version for each device. This process ensures that all hardware components are properly updated and can operate with the new firmware, but it does cause temporary disruptions to network traffic as each module reboots.

References: For more detailed information, please refer to the Cisco Nexus 9000 Series FPGA/EPLD Upgrade Release Notes, where it discusses the impact of EPLD upgrades and the necessity of multiple reboots during the process1. Additionally, the Cisco Nexus 9000 Series NX-OS Software Upgrade and Downgrade Guide provides guidelines on the upgrade process, including the disruptive nature of EPLD upgrades

To configure the Cisco IMC server management NIC for autonegotiation, you should select the shared LOM setting. This setting allows the Cisco IMC to share the LAN on motherboard (LOM) ports with the host operating system and negotiate the speed and duplex settings automatically. The shared LOM setting also provides redundancy and failover capabilities for the Cisco IMC management access. The other settings (Cisco card, dedicated, and shared LOM EXT) do not enable autonegotiation for the Cisco IMC server management NIC.

Cisco NX-OS Data Management Engine (DME) model is a hierarchical representation of the configuration and operational state of the Cisco NX-OS devices. It supports multiple protocols for accessing and manipulating the data, such as NETCONF, RESTCONF, gRPC, and CLI. Among these, NETCONF is the recommended technology for managing a large-scale data center and collecting information from multiple Cisco NX-OS devices using DME model, because it provides a standard, secure, and scalable way of communicating with network devices. References := [Cisco NX-OS Data Management Engine Model]

By default, Cisco UCS Manager excludes local disks from a host firmware package to avoid data loss or corruption during firmware upgrades. The host firmware package contains firmware for other components like network interface controllers, storage controllers, etc., but excludes local disks as they might contain sensitive data.

The PowerShell command in option D is the correct choice for automating the removal of switches from VLANs using the Cisco UCS Manager PowerShell module. This command uses environment variables to specify the VLAN name and switch identifiers, ensuring that the VLAN persists even when it is no longer associated with the switch port. The command structure allows for the removal of the VLAN association from the switch port without deleting the VLAN itself, thus maintaining the VLAN configuration for potential future use.

References: The explanation is based on the Cisco UCS Manager PowerShell module documentation, which provides details on scripting and automation capabilities for managing Cisco UCS environments.

To accomplish the goal of adding all devices already logged in and learned to the Fibre Channel active database, the customer should enable port security and device aliases on the Cisco MDS 9000 series switch. Port security is a feature that allows the switch to restrict the number and type of devices that can log in to a Fibre Channel port. Port security can be configured to automatically add the devices that are already logged in and learned to the active database, and prevent any unauthorized devices from logging in. Device aliases are user-friendly names that can be assigned to devices based on their World Wide Names (WWNs). Device aliases can be used to simplify the management and configuration of devices, as well as to enhance the security and visibility of the Fibre Channel network. Device aliases can also be automatically added to the active database along with the port security information, and can be used for zoning and other operations. References :=

Option C meets the security hardening requirements for Cisco UCS C-Series servers’ out-of-band management. It ensures that all traffic is encrypted, uses nondefault ports, and provides private administrative sessions, which align with the company’s security policy

 The command set in Option C correctly outlines the steps to configure a named VSAN called “VSAN10” with the specified requirements. It includes creating the VSAN with ID 10, assigning an FCoE ID of 20, and attaching it to port 2 in slot 1.

References := Detailed commands and configurations for VSANs can be found in the Cisco Data Center Core Technologies documentation, particularly in the sections that cover Fibre Channel switch mode and VSAN configuration

 The backup operation type that does not include the Preserve Identities feature is the logical configuration. This type of backup includes the settings and configurations that are logically defined within the Cisco UCS Manager, such as service profiles, policies, and management settings. However, it does not include the unique identifiers or ‘identities’ such as MAC addresses, WWN pools, and UUIDs, which are preserved in other types of backups like system configuration and full state.

References: The information about different backup operation types and the specifics of what each includes can be found in the Cisco Data Center Core Technologies documentation and the Cisco UCS Manager Backup and Restore Management Guide1.

 Changing the boot order during setup and applying new requirements multiple times can be achieved by setting the boot configuration directly through the BIOS. This allows the engineer to modify the boot order as needed, separate from the configured boot order in Cisco IMC. References: The DCCOR course discusses server boot order configuration and the use of BIOS settings for such purposes.

 The solution that meets the requirements for implementing an automation solution to allow the backup of the configuration of Cisco Nexus series switches to a centralized location is the Guest Shell. The Guest Shell is a Linux-based container that runs on the Cisco Nexus operating system and provides a secure environment for running Python scripts and custom applications. The Guest Shell supports the RPM packaging format, which allows the team-developed custom monitoring scripts to be easily installed and managed. The Guest Shell is isolated from the underlying Cisco Nexus operating system, which means that it has no impact on the operating system if the resource contention occurs. The Guest Shell also allows the use of Python to expand the existing automation framework, such as using the NX-API or the Cisco Nexus Python SDK to interact with the switch configuration and state. References :=

 In a VXLAN-based data center interconnect scenario where the transport supports a maximum MTU of 1554 bytes and does not support outbound traffic replication, the engineer must use BGP to announce host reachability. This allows for the advertisement of host routes over the BGP session, enabling remote VTEPs to learn about hosts in the interconnected data centers without relying on traffic replication.

To meet the requirements of building a lab replica of a Cisco UCS production environment, the file must be exported in XML format using an encrypted method. Option B, Protocol SCP (Secure Copy Protocol), is used for securely transferring computer files between a local and a remote host or between two remote hosts. Option C, Type Full state, ensures that the complete configuration and state are included in the exported file. References:

 A full state backup of a Cisco UCS Manager database performs a complete binary dump of the database as a .bin file, not a .txz or a .sql file. A full state backup contains all of the configurations and all of the runtime states and statuses of the Cisco UCS domain, but not the passwords. A full state backup can be used to restore the Cisco UCS Manager database to the same or a different fabric interconnect, as long as the hardware configuration is identical. References := Implementing and Operating Cisco Data Center Core Technologies (DCCOR) - Cisco, Chapter 5: Implementing Cisco Unified Computing System Rack Servers, Section: Back Up and Restore the Cisco UCS Manager Database

 The command “alert-group Inventory user-def-cmd show logging last 100” is used to configure the Smart Call Home feature to generate an email with the last 100 lines of the log when new hardware is inserted. This command specifies the alert group ‘Inventory’ and the user-defined command to show the last 100 lines of the logging buffer

The FCoE uplink port type is designed to carry Fibre Channel over Ethernet traffic, which is typically used for storage server communication. Configuring port E1/31-32 as FCoE uplinks will ensure that only storage server traffic for VLAN 200 is forwarded, aligning with the requirement to dedicate these ports solely for storage traffic
