2V0-21.23 Question 195
Select 3An administrator is tasked with deploying VMware vCenter High Availability (vCenter HA) in their environment to ensure fault tolerance. The vCenter Server Appliance (VCSA) is already installed and running. Which of the following prerequisites must be met before enabling vCenter HA?
- A
All vCenter HA nodes must be deployed on the same ESXi host for network efficiency.
- B
The vCenter Server Appliance must have a static IP address configured.
- C
A dedicated port group for vCenter HA network traffic must be available.
- D
The vCenter Server Appliance must be configured with at least one virtual disk of 100 GB or more.
- E
The vCenter Server Appliance must have SSH enabled.
Show answer and explanation
Correct answers: B, C, E
Explanation
To successfully deploy and configure VMware vCenter High Availability, certain prerequisites must be met. The vCenter Server Appliance must have a static IP address and SSH enabled for configuration. Additionally, a dedicated port group for vCenter HA network traffic is required to ensure proper communication and isolation. These prerequisites ensure the stability and functionality of the vCenter HA cluster. Deploying all nodes on a single host is not recommended, and while disk space is important, there is no specific requirement for a 100 GB virtual disk.
- A. Incorrect.
Incorrect: Deploying all vCenter HA nodes on the same ESXi host is not recommended as it creates a single point of failure. vCenter HA requires nodes to be distributed across multiple hosts if possible.
- B. Correct.
Correct: A static IP address is required for the vCenter Server Appliance to ensure consistent network communication between the active, passive, and witness nodes in the vCenter HA cluster.
- C. Correct.
Correct: A dedicated port group for vCenter HA network traffic is necessary to ensure proper isolation and performance of the HA traffic.
- D. Incorrect.
Incorrect: While sufficient disk space is important for the vCenter Server Appliance, there is no specific requirement for a 100 GB virtual disk to enable vCenter HA.
- E. Correct.
Correct: SSH must be enabled on the vCenter Server Appliance for the vCenter HA configuration process to succeed, as it uses SSH to transfer configuration files between nodes.
