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
✓
Failure of designated monitored interfaces exceeding the failure threshold count.
Failover triggers include unit power loss, critical interface failure thresholds being met, kernel/hardware crashes, or failure of health check heartbeats over the failover link.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Failure of designated monitored interfaces exceeding the failure threshold count.
Why this is correct
Monitored interface failures exceeding thresholds trigger failover.
- ✓
Loss of power or complete hardware crash on the active unit.
Why this is correct
Hardware failure or power loss on the active unit triggers failover.
- ✗
An FMC software policy deployment to the standby unit.
Why it's wrong here
Deploying policies does not cause a failover event; policies are pushed to both units.
- ✓
Loss of keepalive heartbeats across the dedicated failover link.
Why this is correct
Heartbeat failure across the failover link triggers active/standby transition.
- ✗
A minor latency spike of 5 milliseconds on an internal routed data interface.
Why it's wrong here
Minor latency spikes do not trigger failover.
