VMware Exam 3V0-42.23 Topic 5 Question 1 Discussion

Actual exam question for VMware's 3V0-42.23 exam
Question #: 1
Topic #: 5
[All 3V0-42.23 Questions]

What is a design justification for a solution with 3 NSX Manager nodes deployed in a 4 ESXi cluster Management Cluster?

Show Suggested Answer Hide Answer
Suggested Answer: B

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.

Haha, I just hope the exam question doesn't ask us to deploy NSX on a Commodore 64! That would be a real blast from the past.

Option D is intriguing. Separating the NSX Controllers from the Managers could provide more flexibility and scalability. But I'd need to understand the tradeoffs better.

I agree with Ciara. Redundancy is key for mission-critical systems like NSX, and Option B addresses that well.

I prefer option D because it allows for more flexibility in hosting NSX Controllers separately from NSX Managers.

Option B sounds like the best choice to me. Having multiple NSX Manager nodes will ensure redundancy and prevent a single point of failure in the control and management planes.
