PCNSE Practice Question: Managing Troubleshooting and High Availability
An administrator needs to verify the health of HA links. Which CLI command displays the current status of HA1, HA2, and HA3 links?
⚠ Common exam trap
Many exam-takers confuse 'show high-availability state' with 'show device-info' or 'show session info', assuming general system or session data includes HA link details, but only the dedicated HA command provides the granular link status required for this verification.

Correct answer & explanation
✓
show high-availability state
The 'show high-availability state' command is the correct CLI command to verify the health of HA1, HA2, and HA3 links because it displays the current status, link state, and any failures for each HA link in a Palo Alto Networks firewall. This command provides a comprehensive view of the HA control link (HA1), data link (HA2), and backup link (HA3), including their operational status and packet statistics, which is essential for troubleshooting high-availability configurations.
