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
✓
Execute the 'show cluster info' and 'show cluster state' commands on the firewall CLI to verify node membership and sync status.
Troubleshooting cluster sync issues involves examining cluster health status via CLI commands (e.g., 'show cluster info'), reviewing FMC deployment history logs, and verifying Cluster Control Link connectivity.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Execute the 'show cluster info' and 'show cluster state' commands on the firewall CLI to verify node membership and sync status.
Why this is correct
CLI cluster show commands provide real-time cluster health and membership details.
- ✓
Verify physical connectivity, MTU settings, and packet loss on the Cluster Control Link (CCL) interface.
Why this is correct
CCL issues like MTU mismatch or packet loss break cluster synchronization.
- ✗
Check the BGP routing table on the core switch for missing Autonomous System path attributes.
Why it's wrong here
BGP attributes do not cause cluster configuration sync failures.
- ✓
Examine the FMC deployment task history and error logs to identify specific configuration push failures to the cluster nodes.
Why this is correct
FMC deployment logs show why configuration pushes failed to specific nodes.
- ✗
Review the VMware vCenter datastore utilization for disk space errors.
Why it's wrong here
Datastore space is unrelated to cluster configuration sync.
