2V0-41.24 Question 26
Select 3You are tasked with deploying a new NSX-T environment for your organization. The design document specifies that the NSX Management Cluster must be highly available and resilient. Which of the following considerations must you take into account when setting up the NSX Management Cluster?
- A
The NSX Management Cluster must consist of exactly three NSX Manager nodes.
- B
All NSX Manager nodes in the cluster should be deployed in the same physical datacenter for optimal performance.
- C
The NSX Manager nodes should communicate over a reliable high-bandwidth network with low latency.
- D
The NSX Management Cluster requires quorum to operate, which means at least two nodes must be healthy.
- E
A single NSX Manager node in the cluster is sufficient for API and management plane functionality during node failures.
Show answer and explanation
Correct answers: A, C, D
Explanation
To properly configure a highly available NSX Management Cluster, it is essential to deploy exactly three NSX Manager nodes. These nodes must communicate over a reliable high-bandwidth, low-latency network to ensure cluster health and synchronization. Additionally, the cluster requires quorum (at least two healthy nodes) to operate correctly. Distributing the nodes across different physical datacenters improves resiliency, avoiding single points of failure.
- A. Correct.
Correct. The NSX Management Cluster must have exactly three nodes for high availability and proper functionality. This ensures redundancy and quorum.
- B. Incorrect.
Incorrect. Deploying all NSX Manager nodes in the same physical datacenter is not recommended for resiliency, as it creates a single point of failure. NSX supports cross-site clusters for enhanced availability.
- C. Correct.
Correct. A reliable high-bandwidth network with low latency is critical for communication between the NSX Manager nodes to maintain cluster health and synchronization.
- D. Correct.
Correct. The NSX Management Cluster requires quorum to operate, meaning at least two out of three nodes must be healthy to ensure proper functionality of the control and management planes.
- E. Incorrect.
Incorrect. While a single NSX Manager node can handle some operations temporarily, it is not sufficient for full functionality or maintaining cluster health during node failures. At least two nodes are required for quorum.
