VCP-VCF Administrator 2024 Question 324
Single answerA VMware Cloud Foundation administrator observes that vCLS (vSphere Cluster Services) VMs are not being deployed in one of the vSphere clusters within their environment. Upon investigation, the administrator notices that DRS is enabled on the cluster. What could be the reason for the failure of vCLS VM deployment, and what action should the administrator take to resolve it?
- A
No compatible datastore is available for vCLS VM placement.
- B
DRS is set to manual mode, preventing vCLS VM deployment.
- C
vCLS VM placement is blocked by a custom affinity rule.
- D
The cluster has insufficient CPU and memory resources to deploy vCLS VMs.
Show answer and explanation
Correct answer: A
Explanation
vCLS VMs ensure basic cluster services are available, such as health and workload placement, even when vCenter is unavailable. For vCLS VMs to be deployed, at least one compatible datastore must be accessible to the cluster. If no compatible datastore is available, the deployment will fail. The administrator should verify datastore availability and accessibility to resolve the issue.
- A. Correct.
Correct. vCLS VMs require a compatible datastore for deployment. If no compatible datastore is available, the VMs cannot be deployed. The administrator should ensure at least one shared datastore is accessible to the cluster.
- B. Incorrect.
Incorrect. vCLS VMs can still be deployed even if DRS is set to manual mode. DRS mode does not directly impact the deployment of vCLS VMs.
- C. Incorrect.
Incorrect. While custom affinity rules could theoretically block vCLS VMs, this is not a common issue unless explicitly configured by the administrator. This is not the most likely cause in this scenario.
- D. Incorrect.
Incorrect. vCLS VMs require minimal CPU and memory resources. Resource constraints are rarely a reason for deployment failure unless the cluster is critically overcommitted.
