VMware NSX 4.x Professional (2024) — Question 39

An NSX administrator is creating a Tier-1 Gateway configured in Active-Standby High Availability Mode. In the event of node failure, the failover policy should not allow the original failed node to become the Active node upon recovery.
Which failover policy meets this requirement?

Answer options

• A. Enable Preemptive
• B. Non-Preemptive
• C. Preemptive
• D. Disable Preemptive

Correct answer: B

Explanation

The Non-Preemptive policy ensures that once a node fails and recovers, it does not take over as the Active node again, which aligns with the requirement. In contrast, the Enable Preemptive and Preemptive options allow the failed node to reclaim its Active status upon recovery, which is not desired in this scenario. The Disable Preemptive option does not specifically address the failover behavior needed.
