2V0-32.24 Question 56
Select 3An organization plans to deploy vRealize Operations for monitoring its VMware infrastructure. They want to ensure high availability (HA) for their deployment to minimize downtime during node failures. Which of the following statements are true about vRealize Operations High Availability (HA) mode?
- A
In HA mode, a single replica node is created to take over in case the primary node fails.
- B
HA mode requires at least three nodes: one primary node, one replica node, and one data node.
- C
The replica node in HA mode processes live data alongside the primary node.
- D
HA mode is automatically enabled during a standalone deployment of vRealize Operations.
- E
Enabling HA mode increases resource requirements, as the replica node needs the same resources as the primary node.
Show answer and explanation
Correct answers: A, B, E
Explanation
High Availability (HA) mode in vRealize Operations ensures minimal downtime by using a replica node that takes over in case of a failure in the primary node. It requires at least three nodes (primary, replica, and data) to maintain quorum and operational consistency. However, enabling HA mode increases resource requirements due to the need for a replica node with identical resource allocations as the primary node. HA mode is not automatically enabled and cannot be configured in a standalone deployment.
- A. Correct.
Correct: In HA mode, a single replica node is created to take over in case the primary node fails, ensuring availability.
- B. Correct.
Correct: HA mode requires a minimum of three nodes to function properly: a primary node, a replica node, and at least one data node for quorum.
- C. Incorrect.
Incorrect: The replica node does not process live data; it remains in standby mode to take over only if the primary node fails.
- D. Incorrect.
Incorrect: HA mode is not automatically enabled during a standalone deployment; it must be explicitly configured in a clustered deployment.
- E. Correct.
Correct: Enabling HA mode increases resource requirements as the replica node mirrors the primary node's resources to ensure failover capability.
