2V0-21.23 Question 196
Select 2An organization is setting up VMware vCenter High Availability (vCenter HA) to ensure minimal downtime in case of a failure. The administrator has created the Active, Passive, and Witness nodes but notices that the vCenter HA cluster is not functioning as expected. Upon investigation, the administrator discovers that there are issues with the network configuration. Which of the following steps are necessary to resolve the issue and ensure proper vCenter HA functionality?
- A
Ensure that the vCenter HA network is on a separate, dedicated subnet.
- B
Verify that all nodes (Active, Passive, and Witness) can communicate with each other using the vCenter HA network.
- C
Configure a static IP address for each vCenter HA node on the management network.
- D
Verify that the default gateway for the vCenter HA network is reachable from all nodes.
- E
Ensure that the vCenter HA network has a valid DNS configuration.
Show answer and explanation
Correct answers: A, B
Explanation
The vCenter HA network is critical for communication between the Active, Passive, and Witness nodes. To ensure proper functionality, it should be configured on a dedicated subnet with static IP addresses. Additionally, all nodes must be able to communicate with each other over this network. Misconfigurations or connectivity issues can prevent the vCenter HA cluster from functioning as expected.
- A. Correct.
Ensuring that the vCenter HA network is on a separate, dedicated subnet is a best practice to avoid network conflicts and ensure proper communication between the vCenter HA nodes.
- B. Correct.
All nodes must be able to communicate with each other using the vCenter HA network for the cluster to function correctly. Communication issues can break the HA functionality.
- C. Incorrect.
Static IP addresses are required for vCenter HA, but they need to be configured on the vCenter HA network, not the management network, as vCenter HA traffic occurs on its dedicated network.
- D. Incorrect.
A default gateway is not required for the vCenter HA network, as it is used exclusively for internal communication between the nodes.
- E. Incorrect.
DNS configuration is not necessary for the vCenter HA network, as it relies on IP-based communication between the nodes.
