2V0-21.23 Question 338
Select 2An administrator needs to update a VMware ESXi host in a vSphere environment to the latest version. The environment has multiple ESXi hosts in a cluster managed by vCenter Server. The administrator wants to ensure that the update process does not disrupt the running workloads. Which combination of steps should the administrator take to perform the update?
- A
Use vSphere Lifecycle Manager (vLCM) to create a baseline for the desired ESXi version and remediate the cluster.
- B
Manually place the ESXi host into Maintenance Mode before applying the update.
- C
Leverage vSphere DRS to migrate running workloads to other hosts in the cluster before remediation.
- D
Download the ESXi ISO file and use it to boot the host and perform a manual upgrade.
- E
Ensure that the cluster is compliant with HA admission control policies before initiating the update.
Show answer and explanation
Correct answers: A, C
Explanation
The best approach to update ESXi in a vSphere environment with minimal disruption is to use vSphere Lifecycle Manager (vLCM) for automated updates and leverage vSphere DRS to migrate workloads away from the host being updated. Manual steps like placing the host in Maintenance Mode or using an ISO file are unnecessary in this scenario, as vLCM and DRS streamline the entire process.
- A. Correct.
Correct: vSphere Lifecycle Manager (vLCM) provides an efficient and automated way to create baselines and remediate clusters, ensuring ESXi hosts are updated without manual intervention.
- B. Incorrect.
Incorrect: vLCM automatically handles Maintenance Mode during remediation, so manually placing the host into Maintenance Mode is not required.
- C. Correct.
Correct: vSphere DRS ensures that workloads are evacuated from the host being updated, preventing any service disruption during the remediation process.
- D. Incorrect.
Incorrect: Using an ISO file for manual upgrade is not efficient in a cluster environment managed by vCenter Server and vLCM.
- E. Incorrect.
Incorrect: While HA policies are important, they are not directly related to the ESXi update process in this scenario.
