300-710 SNCF Deployment Practice Question
An engineer is troubleshooting a stateful failover issue in a Cisco Secure Firewall Threat Defense Active/Standby high availability pair. The firewall units are passing data traffic, but failover state synchronization fails. Which dedicated interface must be verified for correct physical connectivity and configuration?
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
✓
The Failover and State Link
Stateful failover relies on the Failover Link (and optionally a Stateful Failover Link) to replicate connection tables, translation tables, and other stateful data between primary and standby units.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The Cluster Control Link (CCL)
Why it's wrong here
The CCL is used for firewall clustering, not traditional Active/Standby failover pairs.
- ✗
The Management Interface (eth0)
Why it's wrong here
The management interface is used by FMC to manage each unit, not for stateful failover synchronization.
- ✓
The Failover and State Link
Why this is correct
The failover link and state link carry health checks and stateful session synchronization data between the units.
- ✗
The Diagnostic Interface
Why it's wrong here
The diagnostic interface is used for debugging and auxiliary traffic, not stateful failover sync.
