PCNSA Device Management and Services Practice Question
A network administrator recently changed the admin password on a Palo Alto Networks firewall and logged out. The next day, the administrator attempts to log in via SSH but receives 'access denied' after three attempts. The administrator typically uses SSH from a management workstation. The firewall's management interface is still reachable via ping. The administrator suspects the account may be locked due to failed attempts. Since the administrator is not currently logged in, there is no way to unlock the account remotely. The administrator has physical access to the data center and can connect a laptop to the console port. What is the most efficient way to regain administrative access to the firewall?
⚠ Common exam trap
It's easy for candidates to confuse Palo Alto Networks' password recovery method with Cisco IOS's ROMMON password recovery, leading them to incorrectly select Option A (reboot and interrupt boot process) instead of the correct serial console maintenance mode approach.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Connect via the serial console and use the maintenance mode to reset the admin password.
The Palo Alto Networks firewall's serial console provides access to a maintenance mode that allows the administrator to reset the local admin password without needing to log in. This is the most efficient method when the account is locked due to failed SSH attempts and physical access is available, as it avoids a full reboot or factory reset.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reboot the firewall and interrupt the boot process to reset the admin password.
Why it's wrong here
This is not the standard recovery method; maintenance mode is used.
- ✗
Factory reset the firewall and restore the configuration from a backup.
Why it's wrong here
This is unnecessary and time-consuming.
- ✗
Use the 'debug' command in the management interface to bypass the lockout.
Why it's wrong here
No such command exists for bypassing lockout.
- ✓
Connect via the serial console and use the maintenance mode to reset the admin password.
Why this is correct
This is the official password recovery procedure.
