2V0-21.23 Question 421
Select 4A company's vSphere environment includes multiple VMware ESXi hosts running critical workloads. The administrator has been tasked with updating the ESXi hosts to the latest patch version without disrupting the workloads. The administrator decides to use VMware vSphere Lifecycle Manager (vLCM). Which of the following configurations or actions are required to ensure a smooth update process?
- A
Ensure the ESXi hosts are in a vSphere cluster managed by a single vCenter Server.
- B
Put all ESXi hosts into Maintenance Mode before initiating the update process.
- C
Create a custom baseline in vSphere Lifecycle Manager that includes the desired patch or update.
- D
Enable vSphere DRS to automatically migrate running VMs off the ESXi hosts being updated.
- E
Verify the compatibility of the update with the current hardware and drivers using the Hardware Compatibility List (HCL).
Show answer and explanation
Correct answers: A, C, D, E
Explanation
Updating VMware ESXi hosts requires careful planning to avoid disruption to workloads. VMware vSphere Lifecycle Manager simplifies this process by allowing administrators to create custom baselines, automate host updates, and leverage features like vSphere DRS to migrate workloads. Ensuring hosts are in a managed vSphere cluster and verifying hardware compatibility are critical steps to avoid potential issues during and after the update process.
- A. Correct.
Correct: vSphere Lifecycle Manager operates at the cluster level and is managed via vCenter Server. All hosts must belong to the same vSphere cluster for consistent updates.
- B. Incorrect.
Incorrect: While Maintenance Mode is required during the update process, vLCM can automatically place hosts into Maintenance Mode as part of the procedure. Manually doing this for all hosts upfront is not necessary and could disrupt workloads.
- C. Correct.
Correct: A custom baseline in vLCM allows administrators to define the specific patches or updates that should be applied to the ESXi hosts.
- D. Correct.
Correct: vSphere DRS helps ensure that workloads are automatically migrated off hosts being updated, minimizing disruption during the update process.
- E. Correct.
Correct: Verifying hardware and driver compatibility ensures that the update will not cause issues with the ESXi hosts' underlying hardware.
