Palo Alto Networks Certified Strata Field Engineer (PCSFE) — Question 89

A data center experiences a power outage that results in the reboot of all ESXi servers, including the software firewall's virtual machine (VM). Subsequently, there is a notable decrease in performance. Most end users complain of being unable to access the internet. The system engineer is still able to log in to the firewall management console smoothly.

What is most likely causing this issue?

Answer options

• A. The firewall license has expired.
• B. The dataplane disk partitions are unable to mount after the reboot.
• C. There is configuration file corruption on ESXi server.
• D. The last saved configuration did not save properly in the boot up partition.

Correct answer: B

Explanation

The most likely cause of the issue is that the dataplane disk partitions are unable to mount after the reboot, which would hinder the firewall's ability to process traffic effectively. The other options, such as an expired license or configuration file corruption, would not typically allow the management console to be accessed smoothly, indicating that the core functionality of the VM is impaired.
