2V0-21.23 Question 415
Single answerAn administrator is tasked with updating the ESXi hosts in a vSphere cluster to a new version using VMware vSphere Lifecycle Manager (vLCM). The cluster is configured with a single vSphere Distributed Switch and has DRS enabled in partially automated mode. What action must the administrator take to ensure a successful upgrade process without causing service disruptions?
- A
Place each host in maintenance mode manually before applying the upgrade.
- B
Use vLCM to remediate the cluster, as it automatically manages host maintenance mode and workload migration.
- C
Disable DRS temporarily during the upgrade process to prevent workload migrations.
- D
Manually migrate all workloads to a different cluster before starting the upgrade.
Show answer and explanation
Correct answer: B
Explanation
VMware vSphere Lifecycle Manager is designed to simplify and automate the patching and upgrade process for ESXi hosts in a cluster. During remediation, vLCM utilizes features like DRS to migrate workloads and place hosts into maintenance mode automatically, ensuring minimal disruption to services. Option 2 is correct because it leverages vLCM's built-in capabilities, making manual intervention unnecessary.
- A. Incorrect.
This option is unnecessary because vSphere Lifecycle Manager can handle host maintenance mode automatically as part of the remediation process.
- B. Correct.
This is the correct answer. vLCM can orchestrate the entire upgrade process, including placing hosts in maintenance mode, migrating workloads using DRS, and applying updates.
- C. Incorrect.
Disabling DRS would disrupt workload migration and could lead to service interruptions. It is not recommended during the upgrade process.
- D. Incorrect.
Manually migrating workloads to a different cluster is not required because vLCM is designed to manage workload migrations automatically during remediation.
