2V0-51.23 VMware Horizon 8.x Professional Question and Answers

To enable the Senior Administrator's team, which is part of the "Horizon View Operators" AD group, to connect to vCenter and update the golden image, the Senior Administrator needs to assign the appropriate permissions in the vSphere Client. By adding the group to the vCenter Server with the necessary roles and privileges, members of the "Horizon View Operators" group will be able to access and modify the VMs required for maintaining the desktop pools in the VMware Horizon environment.

An Automated Desktop Pool using Dedicated Full Clone Virtual Machines best meets the requirements because it ensures end-users always receive the same desktop VM, supports backups with VMware's image-based backup tools, and allows for cloning via the vSphere API on a weekly basis. Full clones are standalone VMs that don't depend on a parent VM after being created, making them suitable for image-based backups and consistent user experience.

In the Group Policy Management Editor window shown, the administrator should configure the "VMware Horizon Performance Tracker" setting to be able to see the desktop VM's active session in the vSphere Console. However, this setting is not directly visible in the screenshot provided. The Performance Tracker is a tool that enables the monitoring of session performance and is used for this purpose.

In the list shown, there is no specific setting under "VMware Blast" that directly allows for the monitoring of active sessions in the vSphere Console. Typically, active session monitoring in the vSphere Console is not solely managed via Group Policy but also involves settings within the VMware Horizon Console itself and the vSphere infrastructure.

If the task requires enabling something from Group Policy for better visibility or performance tracking of the VM's active sessions, then the closest relevant setting in the context of VMware Blast would be the "VMware Horizon Performance Tracker" if it was listed or part of another category in the Group Policy settings.

The user’s problem is that their settings for the e-mail client are not being saved across sessions. This means that their user profile, which contains their personal data, settings, and preferences, is not being preserved or synchronized properly. To solve this problem, the administrator can deploy one or more of the following options to manage user profiles in Horizon:

• VMware App Volumes Writable Volumes: This option allows users to store user-installed applications, data, and settings on a disk independent of the VM. Writable volumes can be attached to desktops along with application packages, and they can isolate the user-installed applications from the system-installed applications. Writable volumes can also be configured to capture specific files and registry keys by using the snapvol.cfg policy file. This option can help users retain their e-mail client settings on a writable volume that is attached to their desktop at each login.
• Persona Management: This option allows administrators to manage user profiles by using a remote repository that stores user profiles. Persona Management synchronizes the user profile between the remote repository and the local desktop at login, logout, and at regular intervals during the session. Persona Management also supports profile redirection, which allows administrators to redirect certain folders in the user profile to a network share or a writable volume. This option can help users access their e-mail client settings from the remote repository or the redirected folder at each login.
• VMware Dynamic Environment Manager: This option allows administrators to manage user profiles and policies by using a central share that stores user configuration files. Dynamic Environment Manager captures and applies user settings and preferences based on conditions and triggers, such as location, device, or application launch. Dynamic Environment Manager also supports profile archives, which allow administrators to back up and restore user profiles on demand or on schedule. This option can help users apply their e-mail client settings from the central share or the profile archive at each login.

The other options are not valid options for managing user profiles in Horizon:

• Roaming Profiles: This option is a native Windows feature that allows users to access their user profile from any computer in a domain by storing it on a network share. However, this option is not recommended for Horizon because it can cause long login times, profile corruption, and data loss due to its synchronous and overwrite behavior. Roaming profiles are also incompatible with instant clones and linked clones.
• Flexible profiles: This option does not exist in Horizon or Windows. It might be confused with Flex Profiles, which is a third-party product from Liquidware that provides profile management solutions similar to Dynamic Environment Manager.

The following is the correct answer for the drag and drop question:

• Administrator -> Performs all desktop, session, and pool-related operation.
• Inventory Administrator -> Performs all administrative functions and applies to an Access Group.
• Local Administrator -> No rights to manage Cloud Pod or the Global Data Layer.

Predefined Administrator Roles (vmware.com)

The predefined administrator roles in Horizon console are designed to provide different levels of access and control over the Horizon environment. Each role has a set of privileges that grant the ability to perform specific actions or view certain information. You can assign these roles to users or groups on the root access group, which gives them access to all inventory objects in the system, or on a specific access group or federation access group, which limits their scope to the objects within that group. You cannot modify the predefined roles, but you can create custom roles by selecting individual privileges.

The Administrator role is the most powerful role in Horizon console. It allows the user to perform all administrative operations, including creating and managing desktop pools, sessions, farms, applications, global settings, and other administrators. In a Cloud Pod Architecture environment, this role also enables the user to configure and manage a pod federation and manage remote pod sessions. The Administrator role on the root access group is equivalent to a super user role, as it gives full access to everything in the system. Therefore, you should assign this role to a limited number of users.

The Inventory Administrator role is similar to the Administrator role, but it applies only to an access group. This means that the user can perform all administrative functions on the inventory objects that belong to that access group, such as desktop pools, farms, applications, and sessions. However, the user cannot manage global settings or other administrators. This role is useful for delegating administration of specific resources to different users or groups.

The Local Administrator role is a restricted version of the Inventory Administrator role. It applies only to an access group and does not grant any rights to manage Cloud Pod Architecture features or the Global Data Layer. This means that the user can only manage local inventory objects within that access group, such as desktop pools, farms, applications, and sessions. This role is suitable for administrators who do not need to access or modify global settings or cross-pod resources.

The Help Desk Administrator role is a specialized role that allows the user to perform desktop and application actions for troubleshooting and support purposes. These actions include shutting down, resetting, restarting, logging off, disconnecting, and sending messages to users’ desktops or applications. The user can also perform remote assistance actions such as ending processes or viewing system information for a user’s desktop or application. The user cannot create or modify any inventory objects or settings with this role.

VMware Horizon is designed to deliver a virtual desktop and application infrastructure, providing IT with a modern, streamlined approach to deliver, protect, and manage Windows and Linux virtual desktops and applications while containing costs and ensuring that end users can work anytime, anywhere, on any device. Horizon 8 supports flexible hybrid and multi-cloud deployment options and offers an optimized experience with unified communication and collaboration tools. The VMware Blast Extreme Protocol, included with Horizon 8, is a dynamic display protocol that delivers an immersive, feature-rich user experience across devices, locations, media, and network connections​​.

VMware Workspace ONE UEM (Unified Endpoint Management) is crucial for ensuring that end-user devices comply with an organization's IT policies. It manages and secures endpoints like smartphones, tablets, laptops, and desktops, streamlining operational tasks for IT while ensuring corporate data security.

VMware Workspace ONE Access facilitates secure and simplified access to enterprise applications, providing single sign-on capabilities and conditional access based on user authentication. This ensures that users can access the resources they need efficiently while maintaining the security of the organization's data and applications.

The disconnections of external sessions while internal sessions remain stable suggest an issue with the network infrastructure external to the Horizon environment, specifically with the load balancer placed in front of the Unified Access Gateway (UAG) appliances. Misconfigurations such as improper session persistence settings can lead to sessions being disconnected or improperly routed, causing the observed random disconnections.

In VMware Horizon, to designate a Home Site for a user, you would use the "Cloud Pod Architecture" feature, which allows you to set home sites and manage global entitlements across multiple pods and sites in a Horizon environment.

In the exhibit's menu on the left, you should click on "Cloud Pod Architecture" to proceed with designating a Home Site for a user.

To increase the capacity and resiliency of VMware Horizon desktop pools, deploying Horizon on VMware Cloud on AWS or in a remote data center are viable options. VMware Cloud on AWS provides a scalable and secure cloud platform, allowing for quick expansion and disaster recovery capabilities. Similarly, deploying Horizon in a remote data center can provide geographical diversity, reducing the impact of localized disasters and improving overall resilience.

Load balancing is a feature that allows administrators to distribute the load of published desktop and application sessions across multiple RDS hosts in a farm. Load balancing can improve the performance and availability of the sessions and the hosts. Horizon offers two ways of configuring load balancing for RDS hosts: using load balancing settings in Horizon Console or using custom load balancing scripts.

The load balancing settings in Horizon Console allow administrators to define how Horizon calculates the server load index, which indicates the load on each RDS host. The server load index can range from 0 to 100, where 0 represents no load and 100 represents full load. A server load index of -1 indicates that load balancing is disabled. Horizon uses the server load index to determine which RDS host is the best candidate for placing a new session request.

The load balancing settings in Horizon Console include the following check boxes that can be selected to influence the load balancing behavior:

• The use custom script setting for customized RDSH load balancing: This setting allows administrators to override the default behavior of the load balancing settings and control the placement of new sessions by writing and configuring custom load balancing scripts. The custom scripts must write the server load index to a specific registry key on each RDS host. Horizon will use the value from the registry key instead of calculating it from the other settings.
• The Include Session Count setting to include the session count on the RDSH for load balancing: This setting allows administrators to include the number of sessions (connected, pending, and disconnected) on each RDS host as a factor in calculating the server load index. By default, Horizon uses the following formula to calculate the server load index based on the session count: (connected sessions + pending sessions + disconnected sessions)/ (maximum session count). If the maximum session count is configured as unlimited, Horizon falls back to using the absolute number of total sessions.

The other options are not check boxes that can be selected in the load balancing settings in Horizon Console:

• The floating dynamic host profile setting, created in the vSphere profile section: This option is not related to load balancing for RDS hosts, but rather to dynamic environment manager for instant-clone desktops. A dynamic host profile is a vSphere profile that contains configuration settings for instant-clone desktops, such as network settings, domain join settings, and customization scripts. A floating dynamic host profile is a type of dynamic host profile that applies to floating desktop pools, where users are assigned a random desktop from a pool at each login.
• The Horizon DRS setting for fully automated vSphere load balancing: This option is not related to load balancing for RDS hosts, but rather to distributed resource scheduler (DRS) for vSphere clusters. DRS is a feature that monitors and balances the CPU and memory resources across multiple ESXi hosts in a cluster. DRS can also migrate virtual machines between hosts using vMotion to optimize resource utilization and performance. Horizon DRS is an extension of DRS that integrates with Horizon and provides additional capabilities, such as affinity rules, maintenance mode, and power management. Horizon DRS can be configured with different automation levels, such as fully automated, partially automated, or manual.

To enable an instant-clone pool to use NVIDIA GRID vGPU, the administrator needs to do the following:

• Install NVIDIA GRID vGPU in the physical ESXi hosts and select Shared Direct in the Host Graphics Settings12.
• Prepare a golden image with NVIDIA GRID vGPU configured, including selecting the vGPU profile to use12.
• Take a snapshot of the golden image12.
• In Horizon Console, when creating an instant-clone pool, select Manage Using vSphere Client in the 3D Render field. Instant-clones inherit the settings configured in the vSphere Client for the golden image12.

Therefore, the possible reasons for the issue are:

• The administrator has selected Shared instead of Shared Direct when editing the Host Graphics Settings for the ESXi host in the vCenter Server. This option is for vSGA, not vGPU3.
• The golden image and snapshot that the administrator selected has not been configured for NVIDIA GRID vGPU. The administrator needs to verify that the correct vGPU profile is selected and that the NVIDIA drivers are installed in the golden image4.

The other options are not valid because:

• Horizon 8 does have an explicit 3D renderer option for instant clone, but it is Manage Using vSphere Client, not NVIDIA GRID vGPU12.
• Instant-clone pools do support NVIDIA GRID vGPU as long as the ESXi hosts and the golden image are properly configured12.

VMware Dynamic Environment Manager Application Profiler is a standalone application that simplifies the creation of Flex configuration files and predefined settings for use with VMware Dynamic Environment Manager. Application Profiler analyzes where an application stores its file and registry configuration. The analysis results in an optimized Flex configuration file, which you can edit in the Application Profiler or use directly in the VMware Dynamic Environment Manager environment. With Application Profiler, you can also create application-specific predefined settings, with which you can set the initial configuration state of applications. Save the Flex configuration file with predefined settings to export the current application configuration state1.

Therefore, the two capabilities that are supported by VMware Dynamic Environment Manager Application Profiler are:

• It allows creation of application-specific predefined settings. This means that you can configure the default settings for an application that will be applied when a user launches it for the first time. For example, you can set the language, theme, or preferences of an application using Application Profiler2.
• It analyzes registry and file system location settings for an application. This means that it monitors the changes that an application makes to the registry and file system when it is running, and generates a Flex configuration file that captures those changes. This allows VMware Dynamic Environment Manager to manage the user personalization of those settings across different devices and sessions3.

The other options are not supported by VMware Dynamic Environment Manager Application Profiler:

• It allows individual user personalization of applications. This is not a capability of Application Profiler, but rather of VMware Dynamic Environment Manager itself. Application Profiler only helps to create the Flex configuration files that enable user personalization, but it does not apply them to individual users4.
• It allows third-party user personalization of applications. This is also not a capability of Application Profiler, but rather of VMware Dynamic Environment Manager itself. Application Profiler only works with applications that store their settings in the registry or file system, and does not support third-party user personalization solutions such as AppSense or RES.
• It allows creation of computer templates. This is not a capability of Application Profiler at all. Computer templates are used to create virtual machines or physical computers with a predefined configuration, and are not related to application management or user personalization.

If the Horizon Console does not display the health status of configured Unified Access Gateways (UAGs), it could be due to improper firewall configuration blocking traffic on port 443, which is essential for secure communication. Additionally, a discrepancy between the system name in UAG and the name entered in the Horizon Console can also prevent the console from correctly retrieving and displaying the UAG's health status.

Instant clones are a type of virtual machines that are created by cloning a running parent VM in memory, without requiring a full disk copy. This allows for faster provisioning and updating of RDS hosts in a farm. Instant clones can be patched in a rolling process with zero downtime by using the push-image operation, which replaces the existing instant clones with new ones that have the latest patches applied. The push-image operation can be performed on a per-farm basis or on multiple farms at once. The push-image operation preserves the user sessions and data on the existing instant clones until they are logged off or disconnected, and then deletes them. The new instant clones inherit the same settings and assignments as the old ones. Therefore, to deploy a RDS farm that can be patched in a rolling process with zero downtime, the administrator should create an instant-clone RDS desktop farm. References: Instant Clones for RDSH in VMware Horizon 7.1 and [VMware Horizon 8.x Professional Course]

To entitle users and groups to pools, you need to perform the following steps:

• During pool creation in the entitlement pane, click on add, search for users and groups in the Active Directory, continue and finish the pool creation. This option allows you to entitle users and groups to a desktop or application pool at the same time as you create the pool3.
• Navigate to Inventory > Desktops > check mark a pool > click on Add Entitlement. This option allows you to add entitlements to an existing desktop or application pool after you create the pool4.
• Navigate to Users and Groups > Entitlements > click on Entitlements > click on Add Entitlements, search for users and groups in the Users pane and add the desired desktop pool in the next pane Desktop Pools. This option allows you to review and manage the entitlements for users and groups from a single location5.

The other options are not required or valid for entitling users and groups to pools. Running the Active Directory entitlement script in the golden master is not necessary as Horizon 8 automatically synchronizes with Active Directory domains that are configured in Horizon Console6. Specifying the desired Active Directory OU for the VMs during pool creation does not automatically add the preconfigured associated user group to the Horizon entitlements as you still need to select the users or groups from the search results7. References := 3: VMware Horizon 8 Documentation: Add Entitlements During Pool Creation 4: VMware Horizon 8 Documentation: Add Entitlements After Pool Creation 5: VMware Horizon 8 Documentation: Review and Manage Entitlements 6: VMware Horizon 8 Documentation: Active Directory Requirements for Horizon Connection Server 7: VMware Horizon 8 Documentation: Create an Automated Desktop Pool

The default URL used to access the Horizon Console is https:// /admin, where is the fully qualified domain name of the Connection Server instance. This URL allows you to log in to Horizon Console by using a secure (TLS) connection. You can also use the IP address of the Connection Server instance instead of the FQDN, but this might result in blocked access or reduced security due to certificate mismatch. You cannot use https://localhost to connect from the Connection Server host, but you can use https://127.0.0.1 instead. The other options are not valid URLs for Horizon Console.  References: Log In to Horizon Console

To monitor the advanced metrics of desktop sessions in Horizon Console, you need to use the Horizon Help Desk Tool. This is a web application that you can use to get the status of Horizon 8 user sessions and to perform troubleshooting and maintenance operations1. You can also view performance details for a virtual or published desktop session that uses the PCoIP or VMware Blast display protocol2.

To access the Horizon Help Desk Tool, you need to click on the Monitoring tab on the left side of the Horizon Console. Then, you need to select Help Desk from the drop-down menu. This will open the Horizon Help Desk Tool in a new browser tab. You can then search for a user, machine, or pool and view the session details. You can also click on More to see the advanced metrics such as latency, bandwidth, protocol, and frame rate1.

To enable a virtual machine to power on with a PCI graphics accelerator, such as a GPU, attached to it, the administrator needs to reserve all guest memory for that virtual machine. This is because PCI devices require direct memory access (DMA) to function properly, and memory overcommitment can interfere with DMA operations. Reserving all guest memory ensures that no memory swapping or ballooning occurs on the virtual machine, and that the memory address space is contiguous and available for DMA56.

The other options are not required or valid because:

• Enabling Video Card 3D Graphics is not necessary for using a PCI graphics accelerator. This option is for using software-accelerated graphics or virtual shared graphics acceleration (vSGA) on a virtual machine7.
• Setting Memory Shares to High does not guarantee that all guest memory will be reserved. Memory shares only affect how memory resources are distributed among competing virtual machines when there is memory contention on the host. Memory shares do not prevent memory overcommitment or swapping.
• Disabling CPU Hot Plug does not affect the use of a PCI graphics accelerator. CPU Hot Plug allows adding or removing virtual CPUs from a powered-on virtual machine. It has no relation to PCI devices or DMA operations.

In VMware Horizon, predefined roles such as Inventory Administrators and Desktop Pool Administrators are designed to provide granular access control within the Horizon Console. Inventory Administrators typically have permissions related to managing the overall inventory of virtual desktops and applications, whereas Desktop Pool Administrators are specifically focused on managing and configuring desktop pools, including their settings, assignments, and provisioning.
