VMware Exam 3V0-42.23 Topic 5 Question 1 Discussion

3 NSX Manager Nodes for HA & Redundancy (Correct Answer - B):

NSX requires 3 Manager nodes for high availability (HA) and Control Plane redundancy.

If a single NSX Manager node fails, the other nodes continue to operate, preventing single points of failure.

Incorrect Options:

(A - Run All Nodes on One Host):

This contradicts best practices, as NSX Manager nodes should be distributed across multiple hosts.

(C - Reducing Control Plane to a Single Point of Failure):

The 3-node setup prevents this, ensuring failover capability.

(D - Separating NSX Controllers from Managers):

In NSX-T 3.x/4.x, NSX Controllers are part of the Manager cluster, so there are no separate NSX Controllers.
