Citrix ADC 13 Administrator — Question 29

Scenario: A Citrix Administrator is performing a disaster recovery test and decided to fail over the NetScaler high availability (HA) pair appliances. The administrator noticed that the failover is NOT working as expected in item text, and the Secondary NetScaler 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 with the NetScalers?

Answer options

• A. HA monitoring is enabled on a disabled interface of the Primary Node.
• B. The Independent network configuration (INC) mode is enabled on the Primary Node.
• C. HA heartbeats are only seen on some enabled interfaces of the Secondary Node.
• D. HA monitoring is enabled on an interface of the Secondary Node that shows as ENABLED, DOWN.

Correct answer: B

Explanation

The correct answer is B because enabling the Independent network configuration (INC) mode on the Primary Node can prevent proper communication between the nodes, thus hindering failover. Other options, while they may indicate issues, do not directly explain the failure of the Secondary NetScaler to take over as Primary in this scenario.
