PCNSE Paloalto Networks Palo Alto Networks Certified Security Engineer (PCNSE) PAN-OS 11.0 Free Practice Exam Questions (2025 Updated)

A firewall administrator is investigating high packet buffer utilization in the company firewall. After looking at the threat logs and seeing many flood attacks coming from a single source that are dropped by the firewall, the administrator decides to enable packet buffer protection to protect against similar attacks.

The administrator enables packet buffer protection globally in the firewall but still sees a high packet buffer utilization rate.

What else should the administrator do to stop packet buffers from being overflowed?

An administrator notices interface ethernet1/2 failed on the active firewall in an active / passive firewall high availability (HA) pair Based on the image below what - if any - action was taken by the active firewall when the link failed?

During the implementation of SSL Forward Proxy decryption, an administrator imports the company's Enterprise Root CA and Intermediate CA certificates onto the firewall. The company's Root and Intermediate CA certificates are also distributed to trusted devices using Group Policy and GlobalProtect. Additional device certificates and/or Subordinate certificates requiring an Enterprise CA chain of trust are signed by the company's Intermediate CA.

Which method should the administrator use when creating Forward Trust and Forward Untrust certificates on the firewall for use with decryption?

A network engineer has discovered that asymmetric routing is causing a Palo Alto Networks firewall to drop traffic. The network architecture cannot be changed to correct this.

Which two actions can be taken on the firewall to allow the dropped traffic permanently? (Choose two.)

A company has recently migrated their branch office's PA-220S to a centralized Panorama. This Panorama manages a number of PA-7000 Series and PA-5200 Series devices All device group and template configuration is managed solely within Panorama

They notice that commit times have drastically increased for the PA-220S after the migration

What can they do to reduce commit times?

An engineer needs to configure a standardized template for all Panorama-managed firewalls. These settings will be configured on a template named "Global" and will be included in all template stacks.

Which three settings can be configured in this template? (Choose three.)

Which two scripting file types require direct upload to the Advanced WildFire portal/API for analysis? (Choose two.)

Panorama is being used to upgrade the PAN-OS version on a pair of firewalls in an active/passive high availability (HA) configuration. The Palo Alto Networks best practice upgrade steps have been completed in Panorama (Panorama upgraded, backups made, content updates, and disabling "Preemptive" pushed), and the firewalls are ready for upgrade. What is the next best step to minimize downtime and ensure a smooth transition?

An engineer needs to collect User-ID mappings from the company's existing proxies.

What two methods can be used to pull this data from third party proxies? (Choose two.)

A network security engineer is attempting to peer a virtual router on a PAN-OS firewall with an external router using the BGP protocol. The peer relationship is not establishing. What command could the engineer run to see the current state of the BGP state between the two devices?

What does the User-ID agent use to find login and logout events in syslog messages?

Which protocol is supported by GlobalProtect Clientless VPN?

An enterprise network security team is deploying VM-Series firewalls in a multi-cloud environment. Some firewalls are deployed in VMware NSX-V, while others are in AWS, and all are centrally managed using Panorama with the appropriate plugins installed. The team wants to streamline policy management by organizing the firewalls into device groups in which the AWS-based firewalls act as a parent device group, while the NSX-V firewalls are configured as a child device group to inherit Security policies. However, after configuring the device group hierarchy and attempting to push configurations, the team receives errors, and policy inheritance is not functioning as expected. What is the most likely cause of this issue?

Which active-passive HA firewall state describes the firewall that is currently processing traffic?

What happens when the log forwarding built-in action with tagging is used?

An administrator is required to create an application-based Security policy rule to allow Evernote. The Evernote application implicitly uses SSL and web browsing.

What is the minimum the administrator needs to configure in the Security rule to allow only Evernote?

Refer to the exhibit.

An administrator cannot see any of the Traffic logs from the Palo Alto Networks NGFW on Panorama. The configuration problem seems to be on the firewall side. Where is the best place on the Palo Alto Networks NGFW to check whether the configuration is correct?

A)

B)

C)

D)

A firewall engineer supports a mission-critical network that has zero tolerance for application downtime. A best-practice action taken by the engineer is configure an applications and Threats update schedule with a new App-ID threshold of 48 hours. Which two additional best-practice guideline actions should be taken with regard to dynamic updates? (Choose two.)

A network engineer troubleshoots a VPN Phase 2 mismatch and decides that PFS (Perfect Forward Secrecy) needs to be enabled. What action should the engineer take?
