Palo Alto Networks Certified Network Security Engineer (PCNSE) — Question 173

Before you upgrade a Palo Alto Networks NGFW, what must you do?

Answer options

• A. Make sure that the PAN-OS support contract is valid for at least another year.
• B. Export a device state of the firewall.
• C. Make sure that the firewall is running a supported version of the app + threat update.
• D. Make sure that the firewall is running a version of antivirus software and a version of WildFire that support the licensed subscriptions.

Correct answer: C

Explanation

The correct answer is C because ensuring the firewall runs a supported version of the app and threat update is crucial for a successful upgrade. While options A, B, and D may be good practices, they do not directly address the requirement for compatibility with the software version needed for the upgrade.
