300-710 SNCF Management And Troubleshooting Practice Question
An administrator is troubleshooting a high availability (HA) failover link failure between two FTD physical appliances. Which THREE checks should be performed to diagnose physical and logical connectivity between the failover interfaces? (Choose three)
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
✓
Verify physical link lights (LEDs) and cable integrity on the dedicated failover interfaces.
Troubleshooting HA failover links involves checking physical cable connections, verifying interface status via 'show failover', checking IP reachability/ping across the failover interface, and reviewing failover configuration parameters.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Verify physical link lights (LEDs) and cable integrity on the dedicated failover interfaces.
Why this is correct
Physical layer verification is the first step in troubleshooting link failures.
- ✓
Run the 'show failover' command on the FTD diagnostic CLI to inspect mate status and interface monitoring states.
Why this is correct
'show failover' reveals whether the peer is reachable and if interfaces are monitored correctly.
- ✓
Check interface IP configuration and ensure ping reachability across the dedicated failover subnet if layer 3 failover is used.
Why this is correct
IP reachability across the failover link is essential for heartbeat signaling.
- ✗
Change the FTD management IP address on both units.
Why it's wrong here
Management IP addresses do not affect internal HA failover communication.
- ✗
Reboot the FMC to restart failover polling.
Why it's wrong here
FMC does not poll HA failover heartbeats; HA is managed peer-to-peer between the two FTD units.
