Citrix Access Control Administration — Question 58

Scenario: While performing a disaster recovery test, a Citrix Administrator decides to failover the Citrix ADC high availability (HA) pair appliances. The administrator notices that the failover is NOT working as expected, and the secondary Citrix ADC is NOT taking over as primary. The administrator suspects that networking issues may be causing the failure.
What could be the cause of this issue?

Answer options

• A. HA monitoring is enabled on an interface of the secondary node that shows as ENABLED, DOWN.
• B. HA monitoring is enabled on a disabled interface of the primary node.
• C. HA heartbeats are only seen on some enabled interfaces of the secondary node.
• D. The Independent Network Configuration (INC) mode is enabled on the primary node.

Correct answer: A

Explanation

The correct answer is A because if HA monitoring is enabled on an interface of the secondary node that is DOWN, it will prevent the failover from functioning correctly. Option B is incorrect as it refers to the primary node, which doesn't affect the secondary's ability to take over. Option C is also incorrect because HA heartbeats must be consistently seen on all necessary interfaces for reliable failover. Option D does not directly impact the failover process in this context.
