F5 BIG-IP LTM Specialist: Maintain and Troubleshoot — Question 133
An HA pair of LTM devices configured in Active-Standby mode stops responding to traffic and causes an outage. The Active device becomes Standby, but the partner device stays in Standby mode instead of taking over as Active. A reboot and restart of the services brings the LTM device to Active mode for a short time, but then it goes into Standby mode again.
Which two configuration components caused this condition? (Choose two.)
Answer options
- A. VLAN Fail-safe
- B. System Fail-safe
- C. Gateway Fail-safe
- D. Switch Board Failure
- E. Link down on Failover
Correct answer: A, C
Explanation
The correct answers are A (VLAN Fail-safe) and C (Gateway Fail-safe) because these settings can prevent the standby device from taking over as active during a failover situation. The other options do not directly relate to the failover behavior described in this scenario.
