Question 1

A company has a PA-3220 NGFW at the edge of its network and wants to use active directory groups in its Security policy rules. There are 1500 groups in its active directory. An engineer has been provided 800 active directory groups to be used in the Security policy rules.

What is the engineer's next step?

ACreate a Group Mapping with 800 groups in the Group Include List.

BCreate two Group Include Lists, each with 400 Active Directory groups.

CCreate a Group Include List with the 800 Active Directory groups.

DCreate two Group Mappings, each with 400 groups in the Group Include List.

Answer : B

Question 2

A security engineer is informed that the vulnerability protection profile of their on-premises Palo Alto Networks firewall is triggering on a common Threat ID, and which has been determined to be a false positive. The engineer is asked to resolve the issue as soon as possible because it is causing an outage for a critical service The engineer opens the vulnerability protection profile to add the exception, but the Threat ID is missing.

Which action is the most operationally efficient for the security engineer to find and implement the exception?

AReview high severity system logs to identify why the threat is missing in Vulnerability Profile Exceptions.

BOpen a support case.

CReview traffic logs to add the exception from there.

DSelect 'Show all signatures' within the Vulnerability Protection Profile under 'Exceptions'.

Answer : D

Question 3

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?

AEnable PFS under the IKE gateway advanced options.

BEnable PFS under the IPSec Tunnel advanced options.

CAdd an authentication algorithm in the IPSec Crypto profile.

DSelect the appropriate DH Group under the IPSec Crypto profile.

Answer : B

Question 4

Review the screenshots.

What is the most likely reason for this decryption error log?

AThe Certificate fingerprint could not be found.

BThe client expected a certificate from a different CA than the one provided.

CThe client received a CA certificate that has expired or is not valid.

DEntrust is not a trusted root certificate authority (CA).

Answer : D

Question 5

An administrator needs to validate that policies that will be deployed will match the appropriate rules in the device-group hierarchy. Which tool can the administrator use to review the policy creation logic and verify that unwanted traffic is not allowed?

APreview Changes

BManaged Devices Health

CTest Policy Match

DPolicy Optimizer

Answer : C

The Test Policy Match tool in Palo Alto Networks' management systems (such as Panorama or the firewall interface) allows administrators to simulate traffic against configured security policies. This tool is critical for ensuring that the correct policies are applied to specific traffic patterns and that no unintended access is granted.

Key Points:

Test Policy Match enables you to input parameters like source IP, destination IP, application, user, and more, and the system will determine which policy would apply.

It is especially useful for verifying the device-group hierarchy in multi-tenant or Panorama-managed environments, ensuring that inherited or overridden rules are correctly applied.

The tool also helps to proactively check that traffic will be blocked or allowed as intended, reducing misconfigurations and preventing unwanted traffic.

Why not the other options?

A . Preview Changes: This feature is used to review configuration changes before committing them but does not simulate or validate policy matches.

B . Managed Devices Health: This option is related to checking the health and connectivity status of managed devices, not policies.

D . Policy Optimizer: This tool is used to refine existing security policies by identifying overly permissive rules or unused objects, not for testing specific traffic matches.

The Test Policy Match tool is the most appropriate choice for the scenario described.

Question 6

What action does a firewall take when a Decryption profile allows unsupported modes and unsupported traffic with TLS 1.2 protocol traverses the firewall?

AIt blocks all communication with the server indefinitely.

BIt downgrades the protocol to ensure compatibility.

CIt automatically adds the server to the SSL Decryption Exclusion list.

DIt generates an decryption error message but allows the traffic to continue decryption.

Answer : C

Question 7

A standalone firewall with local objects and policies needs to be migrated into Panoram

a. What procedure should you use so Panorama is fully managing the firewall?

AUse the 'import device configuration to Panorama' operation, commit to Panorama, then 'export or push device config bundle' to push the configuration.

BUse the 'import Panorama configuration snapshot' operation, commit to Panorama, then 'export or push device config bundle' to push the configuration.

CUse the 'import device configuration to Panorama' operation, commit to Panorama, then perform a device-group commit push with 'include device and network templates'.

DUse the 'import Panorama configuration snapshot' operation, commit to Panorama, then perform a device-group commit push with 'include device and network templates'.
