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.

Wait, are we really saying D is a good idea? Seems risky to me.

The key here is to identify the design justification that addresses the single point of failure concern. Option B seems to be the best answer, as it specifically mentions mitigating the single point of failure on the Control Plane and Management Plane.

I'm not sure I fully understand the implications of the different options. I'll need to carefully read through each one and think about how the design choices impact the overall system reliability and redundancy.

Okay, let's think this through. Having 3 NSX Manager nodes in a 4 ESXi cluster should provide redundancy and high availability for the management and control plane, which is what option B is describing. I'm pretty confident that's the right answer.

Hmm, I'm a bit confused about the relationship between the NSX Manager nodes and the ESXi cluster. I'll need to review the material on NSX architecture to make sure I understand the design considerations here.

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.
