300-710 SNCF Management And Troubleshooting Practice Question
An FMC high availability (HA) pair has split-brain symptoms due to a management network failure. After restoring network connectivity, the standby unit remains in a 'Failed' state and does not automatically re-synchronize. What is the correct procedure to recover the HA sync?
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
✓
Go to System > Integration > HA, break the HA pairing, and re-establish it using the active unit as the primary.
When FMC HA encounters persistent sync issues after network restoration, the administrator must break the HA relationship and re-establish it, or use the system-level HA synchronization tools to force a re-sync from active to standby.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Run 'system support fmc-ha-sync' from the standby FMC CLI.
Why it's wrong here
FMC high availability is managed through the GUI or specific cloud/system administration scripts, not direct CLI ha-sync commands.
- ✓
Go to System > Integration > HA, break the HA pairing, and re-establish it using the active unit as the primary.
Why this is correct
Breaking and re-establishing the HA pair ensures a clean database sync from the active FMC to the standby.
- ✗
Reboot both FMC units simultaneously.
Why it's wrong here
Rebooting does not clear split-brain database divergence states in an FMC HA pair.
- ✗
From the primary FMC CLI, run 'configure ha restore-sync'.
Why it's wrong here
This is not a valid FMC CLI command syntax for HA recovery.
