2V0-41.24 Question 19
Select 3An organization is deploying NSX-T in their data center and is setting up the NSX management cluster. They want to ensure high availability and reliability for the management plane. Which of the following statements are accurate regarding the NSX management cluster and the management plane?
- A
The NSX management cluster must consist of an odd number of nodes to maintain quorum.
- B
The NSX management plane is responsible for configuring and managing the NSX data plane.
- C
If one NSX manager node fails, the entire NSX management cluster becomes unavailable.
- D
The NSX management cluster nodes communicate with each other using the RabbitMQ protocol.
- E
The NSX management plane operates independently of the NSX control plane.
Show answer and explanation
Correct answers: A, B, E
Explanation
Understanding the NSX management cluster and management plane is critical for designing a reliable and high-performing network virtualization solution. The management cluster must have an odd number of nodes to maintain quorum, and the management plane is responsible for managing the data plane and providing administrator access. It operates independently of the control plane, which ensures modularity and separation of responsibilities.
- A. Correct.
Correct: The NSX management cluster requires an odd number of nodes (typically 3) to maintain quorum and ensure high availability.
- B. Correct.
Correct: The NSX management plane is responsible for configuring and managing the data plane, as well as providing the user interface and API for administrators.
- C. Incorrect.
Incorrect: If one NSX manager node fails, the cluster can still operate as long as quorum is maintained. It does not result in a complete cluster failure.
- D. Incorrect.
Incorrect: The NSX management cluster nodes communicate using a distributed database and protocols like Cassandra, not RabbitMQ.
- E. Correct.
Correct: The NSX management plane is distinct from the control plane, as the latter handles the distribution of routing and switching information to the data plane.
