2V0-21.23 Question 260
Single answerAn administrator is tasked with adding a set of new hosts to an existing vSphere cluster using the Cluster Quickstart workflow. During the process, the administrator notices that the 'vSphere Lifecycle Manager (vLCM)' option is available. What is a key prerequisite for successfully using the Cluster Quickstart workflow with vLCM enabled?
- A
All new hosts must have the same version of ESXi installed before being added to the cluster.
- B
The vSphere cluster must be configured with a single image for vSphere Lifecycle Manager.
- C
The new hosts must have identical hardware configurations to the existing hosts in the cluster.
- D
The vSphere Distributed Switch (vDS) must already be configured before adding the new hosts.
Show answer and explanation
Correct answer: B
Explanation
The Cluster Quickstart workflow simplifies the process of adding hosts to a vSphere cluster, and vSphere Lifecycle Manager (vLCM) enhances this process by managing hosts with a single image. To successfully use vLCM within Cluster Quickstart, the cluster must be configured to use a single image, which standardizes the ESXi version and vendor add-ons across all hosts in the cluster. This ensures consistency and simplifies lifecycle management tasks.
- A. Incorrect.
This is incorrect. The Cluster Quickstart workflow does not require all new hosts to have the same ESXi version pre-installed. The workflow allows for ESXi image remediation using vLCM.
- B. Correct.
This is correct. vSphere Lifecycle Manager in the Cluster Quickstart workflow requires the cluster to use a single image for host management and remediation.
- C. Incorrect.
This is incorrect. Identical hardware configurations are not required as long as the hardware is compatible with the single image used for vLCM.
- D. Incorrect.
This is incorrect. While a vSphere Distributed Switch can be part of the cluster configuration, it is not a prerequisite for using the Cluster Quickstart workflow with vLCM.
