2V0-21.23 Question 292
Select 3An administrator is tasked with setting up a Supervisor Cluster to enable Kubernetes workloads in their vSphere environment. They have completed the prerequisites, including configuring a vSphere Distributed Switch (vDS) and ensuring sufficient resources are available. However, during the setup, they encounter an error stating that the vSphere Namespace cannot be created. What could be the possible cause of this issue?
- A
The workload network is not configured correctly.
- B
The vCenter Server version is not compatible with Supervisor Clusters.
- C
The required storage policy is not assigned to the Supervisor Namespace.
- D
The ESXi hosts are not part of a Distributed Resource Scheduler (DRS) enabled cluster.
- E
The Kubernetes control plane VM is powered off.
Show answer and explanation
Correct answers: A, C, D
Explanation
To create a Supervisor Namespace, certain prerequisites must be met: a properly configured workload network for communication, an assigned storage policy for persistent storage, and an underlying ESXi cluster with DRS enabled for workload management. Missing any of these configurations can lead to namespace creation errors. The other options, while important for overall cluster functionality, are not specific causes of this issue.
- A. Correct.
The workload network must be properly configured to enable communication between Kubernetes components. An incorrect configuration can prevent namespace creation.
- B. Incorrect.
While the vCenter Server version must meet the minimum requirements for Supervisor Clusters, this is not the direct cause of the error related to namespace creation.
- C. Correct.
Each Supervisor Namespace requires a storage policy to be assigned for persistent storage. Without this, the namespace cannot be created.
- D. Correct.
Supervisor Clusters require DRS to be enabled on the underlying ESXi cluster to manage resource allocation and workload placement. If DRS is not enabled, namespace creation will fail.
- E. Incorrect.
The Kubernetes control plane VM is critical for running workloads, but its power state does not directly affect namespace creation.
