350-701 Network Security Practice Question
An engineer configures a Cisco FTD in a high-availability pair with active/standby failover. The primary unit fails, and the standby takes over. After the primary recovers, what must be done to ensure it resumes as active?
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 'failover active' on the primary unit.
In active/standby failover, the active unit can be forced to become standby and the standby active. To make the recovered primary active, the command 'failover active' on the primary or 'failover reset' can be used. However, by default, the primary will not automatically become active unless configured with preempt.
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 'failover active' on the primary unit.
Why this is correct
This forces the primary to become active again.
- ✗
No action is needed; the primary automatically resumes active role.
Why it's wrong here
By default, the primary does not preempt; it stays standby.
- ✗
Reboot the secondary unit.
Why it's wrong here
Rebooting the secondary would cause failover back to primary, but not recommended.
- ✗
Disable and re-enable failover.
Why it's wrong here
This disrupts the HA pair unnecessarily.
