300-710 SNCF Deployment Practice Question
An engineer has deployed an active/standby High Availability pair of Cisco Secure Firewall Threat Defense devices. A failure occurs on the active unit, and a failover successfully takes place. However, upon recovery of the original active unit, it immediately resumes its role as the active unit, causing a brief secondary interruption. Which failover setting governs this behavior?
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
✓
Failover Preempt Configuration
The 'Preempt' setting dictates whether a recovered primary unit will reclaim its active role from the current active unit. By default, preemption may be enabled or disabled depending on configuration preferences.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
MAC Address Persistence Timer
Why it's wrong here
MAC persistence ensures downstream switches update their ARP tables quickly during failover, not unit role takeback.
- ✗
HEMS Poll Frequency
Why it's wrong here
HEMS is not the mechanism for preemption control.
- ✗
Stateful Failover Sync Interval
Why it's wrong here
Sync interval controls how often state information is replicated, not role preemption.
- ✓
Failover Preempt Configuration
Why this is correct
Preempt settings control whether the primary unit automatically takes back the active role when it recovers.
