PCNSE Practice Question: Managing Troubleshooting and High Availability
After upgrading the software on an HA pair, the two firewalls report different HA states. Which command should be used to quickly verify the HA configuration synchronization status?
⚠ Common exam trap
PCNSE candidates often confuse the HA state (active/passive) with configuration synchronization status. The 'show high-availability state' command shows the operational state, not the sync status. After a software upgrade, verifying configuration sync is critical, making 'show high-availability sync-status' the correct command.

Correct answer & explanation
✓
show high-availability sync-status
The 'show high-availability sync-status' command specifically displays the synchronization status of the configuration between HA peers, including whether the active and passive firewalls are in sync, the last sync time, and any pending changes. After a software upgrade, configuration mismatches can occur due to version differences or failed syncs, and this command directly verifies if the configurations are synchronized.
