Palo Alto Networks Certified Network Security Consultant (PCNSC) — Question 17

A firewall that was previously connected to a User-ID agent server now shows disconnected.
What is the likely cause?

Answer options

• A. The server has stopped listening on port 2010.
• B. The Domain Controller service account has been locked out.
• C. The agent is not running.
• D. The firewall was upgraded to a PAN-OS version that is not compatible with the agent version.

Correct answer: D

Explanation

The correct answer is D because upgrading the firewall to an incompatible PAN-OS version can cause disconnection issues with the User-ID agent. Options A, B, and C may indicate different problems, but they do not specifically address the compatibility issue that would arise from a version upgrade.
