2V0-21.23 Question 155
Select 3An administrator is tasked with setting up a new vSphere environment. During the installation of ESXi, they need to ensure that the environment is configured to support vSphere High Availability (HA) and Distributed Resource Scheduler (DRS). What are the necessary steps to properly configure this setup?
- A
Enable vSphere HA and DRS at the cluster level after creating a new cluster.
- B
Ensure the ESXi hosts are added to the cluster and have shared storage configured.
- C
Set up a Distributed Switch before enabling vSphere HA on the cluster.
- D
Ensure that each ESXi host in the cluster is licensed for vSphere Enterprise Plus.
- E
Verify that all hosts in the cluster have compatible CPUs to support vMotion.
Show answer and explanation
Correct answers: A, B, E
Explanation
To set up vSphere High Availability (HA) and Distributed Resource Scheduler (DRS), the administrator must first enable these features at the cluster level and ensure that the ESXi hosts within the cluster are configured with shared storage to support virtual machine failover and migration. CPU compatibility is also a critical requirement to ensure vMotion can function properly across all hosts, which is essential for DRS. While a Distributed Switch offers advanced networking capabilities, it is not mandatory for HA and DRS to function, nor is an Enterprise Plus license specifically required for these features.
- A. Correct.
Correct. vSphere HA and DRS are enabled at the cluster level after creating a cluster in the vSphere environment.
- B. Correct.
Correct. Shared storage is required for vSphere HA and DRS to function correctly, as it enables virtual machine migration and failover.
- C. Incorrect.
Incorrect. Setting up a Distributed Switch is not mandatory for enabling vSphere HA; a Standard Switch can also be used.
- D. Incorrect.
Incorrect. While licensing is important, vSphere Enterprise Plus is not required for enabling vSphere HA and DRS. Lower-level licenses also support these features.
- E. Correct.
Correct. vMotion, which is a prerequisite for DRS, requires compatible CPUs across all hosts in the cluster.
