After a recent security audit, a company is required to enforce more strict validation for all certificate-based authentication, including for GlobalProtect clients. An engineer observes the firewall accepting certificates from a recently compromised intermediate certificate authority (CA). The engineer needs to update the firewall configuration to use an Online Certificate Status Protocol (OCSP) responder to check for revoked certificates in real time.
In which configuration object would the engineer enable OCSP verification for the CAs used in the authentication process?
A network security engineer at a 24/7 online retailer is upgrading an active/passive high availability (HA) cluster of PAN-OS firewalls. The primary goal is to perform the upgrade with no service interruption to online transactions. The engineer has already downloaded the new software to both devices.
Which sequence of actions will meet this requirement?
Which two Palo Alto Networks firewall services are secured by attaching an SSL/TLS service profile to their configuration? (Choose two.)
An administrator is designing a public key infrastructure (PKI) integration for a large-scale deployment with thousands of users authenticating via client certificates. A key design goal is to ensure that certificate revocation status is checked efficiently with minimal impact on firewall performance and minimal delay for the connecting user.
What is the primary advantage of using the Online Certificate Status Protocol (OCSP) instead of certificate revocation lists (CRLs) in this scenario?
A network engineer observes a pattern of anomalous traffic hitting an external-facing zone, including a high volume of TCP packets that are not part of a new session handshake (non-SYN), and a large number of ICMP fragments. The engineer decides to apply a Zone Protection profile to mitigate these potential threats.
Which protection type within the profile must be configured?
When integrating Kubernetes with Palo Alto Networks NGFWs, what is used to secure traffic between microservices?
What is a result of enabling split tunneling in the GlobalProtect portal configuration with the “Both Network Traffic and DNS†option?
An organization's Security policy states that for all outbound web traffic, the TCP session to the external web server must be established by the firewall, not the user's workstation. This requires configuring user web browsers to point to the firewall. Authentication is also required.
Which solution on a PA-Series firewall meets these specific needs?
A network security engineer is reviewing the dynamic update settings for a fleet of firewalls in a financial institution that has a policy prioritizing operational stability above all else. The engineer notes that the current content update threshold is set to 24 hours.
Following the Palo Alto Networks recommended best practices for mission-critical deployments, which adjustment should be made to the threshold?
A company is enabling SSL Forward Proxy to inspect encrypted traffic. A security engineer generates a new certificate on the firewall and flags it with the "Forward Trust" certificate property.
What is the critical next step that must be performed for decryption to function correctly without causing security warnings for end users?
After a recent high availability (HA) failover test on an active/passive cluster, an engineer noted a 30-45 second delay before traffic started flowing through a Link Aggregation Control Protocol (LACP) aggregate interface on the newly active firewall.
What should have been configured to support LACP pre-negotiation to minimize LACP convergence delay?
A PA-Series firewall with all licensable features is being installed. The customer’s Security policy requires that users do not directly access websites. Instead, a security device must create the connection, and there must be authentication back to the Active Directory servers for all sessions.
Which action meets the requirements in this scenario?
A network security engineer is designing a resilient architecture for inspecting traffic in Google Cloud Platform (GCP). The design must ensure that firewall service is maintained even if a single GCP zone becomes unavailable.
Which architecture should be used for the VM-Series firewalls in this use case?
An administrator plans to upgrade a pair of active/passive firewalls to a new PAN-OS release. The environment is highly sensitive, and downtime must be minimized.
What is the recommended upgrade process for minimal disruption in this high availability (HA) scenario?
An administrator is troubleshooting a newly configured site-to-site VPN between a PAN-OS firewall and a third-party policy-based VPN gateway. The tunnel allows traffic between the first pair of configured subnets, but traffic to a newly added remote subnet is failing. The administrator has confirmed that routing and Security policies are correct.
What is the most likely cause of this issue?
A network security engineer wants to create Security policy rules that allow or deny traffic based on a user's department, which corresponds to groups in the company's Active Directory. To achieve this, the firewall needs to retrieve group information from the directory server.
Which configuration object must be created first to establish the connection with the Active Directory server?
An administrator needs to ensure that a firewall can download threat prevention and software updates, but the management port is on an isolated network without internet access.
Which service must be rerouted through a data plane interface using a service route to allow the firewall to download these updates?
An organization runs multiple Kubernetes clusters both on-premises and in public clouds (AWS, Azure, GCP). They want to deploy the Palo Alto Networks CN-Series NGFW to secure east-west traffic within each cluster, maintain consistent Security policies across all environments, and dynamically scale as containerized workloads spin up or down. They also plan to use a centralized Panorama instance for policy management and visibility.
Which approach meets these requirements?
A network administrator is establishing a site-to-site VPN between a Palo Alto Networks firewall and a partner's Check Point Security Gateway. The partner has provided a specific list of local and remote IP address subnets that are permitted through the tunnel. The initial tunnel configuration on the PAN-OS firewall fails during the IKE Phase 2 exchange.
Which configuration step is essential to ensure compatibility with the policy-based Check Point gateway?
A firewall administrator uses Panorama to manage a fleet of firewalls. After successfully onboarding the firewalls to Strata Logging Service and enabling cloud logging via a template, the security operations team reports that they can no longer see new logs on the on-premises Panorama log collectors. Logs are appearing correctly in Strata Logging Service.
Which setting was likely missed in the Panorama template configuration?
An engineer is troubleshooting a failed inter-VSYS communication path between a DMZ-VSYS and an Internal-VSYS. The configuration includes separate virtual routers with next-vr static routes and appropriate Security policies within each VSYS allowing traffic to and from their external zones.
Given that all routing and policy configurations within each individual VSYS are correct, what is the probable cause of the failure?
What is a valid configurable limit for setting resource quotas when defining a new VSYS on a Palo Alto Networks firewall?
A network architect is planning the deployment of a new IPSec VPN tunnel to connect a local data center to a cloud environment. The plan must include all necessary Security policy configurations for both tunnel negotiation and data transit.
Which two Security policy requirements must be included in the implementation plan? (Choose two answers)
What is the purpose of assigning an Admin Role Profile to a user in a Palo Alto Networks NGFW?
Which statement describes the role of Terraform in deploying Palo Alto Networks NGFWs?
What are two valid zone types that can be selected from the zone configuration menu, per Palo Alto Networks best practices? (Choose two.)
When deploying Palo Alto Networks NGFWs in a cloud service provider (CSP) environment, which method ensures high availability (HA) across multiple availability zones?
Which feature can be enabled on a Layer 3 interface but is not available on Layer 2 interfaces?
Which CLI command is used to configure the management interface as a DHCP client?
An NGFW engineer is establishing bidirectional connectivity between the accounting virtual system (VSYS) and the marketing VSYS. The traffic needs to transition between zones without leaving the firewall (no external physical connections). The interfaces for each VSYS are assigned to separate virtual routers (VRs), and inter-VR static routes have been configured. An external zone has been created correctly for each VSYS. Security policies have been added to permit the desired traffic between each zone and its respective external zone. However, the desired traffic is still unable to successfully pass from one VSYS to the other in either direction.
Which additional configuration task is required to resolve this issue?
An NGFW engineer is configuring multiple Panorama-managed firewalls to start sending all logs to Strata Logging Service. The Strata Logging Service instance has been provisioned, the required device certificates have been installed, and Panorama and the firewalls have been successfully onboarded to Strata Logging Service.
Which configuration task must be performed to start sending the logs to Strata Logging Service and continue forwarding them to the Panorama log collectors as well?
When deploying a pair of Palo Alto Networks firewalls in an active/active high availability (HA) cluster what is the dedicated role of the HA3 link?
Palo Alto Networks NGFWs use SSL/TLS profiles to secure which two types of connections? (Choose two.)
