2V0-21.23 Question 351
Single answerAn organization is deploying VMware vSphere with Tanzu to enable Kubernetes workloads in their data center. Their architecture includes vSphere Distributed Switches and a compatible NSX-T Data Center deployment. After configuring the Supervisor Cluster, the team notices that Kubernetes namespaces cannot be created. What lifecycle activity should the administrator prioritize to resolve this issue?
- A
Verify that the vSphere Distributed Switch has the required port group configurations for the Workload Network.
- B
Check if the Kubernetes CLI (kubectl) is properly installed on the administrator's workstation.
- C
Ensure that the NSX-T Edge node has sufficient memory and CPU resources allocated.
- D
Confirm that the vSphere with Tanzu license is properly applied to the vSphere cluster.
Show answer and explanation
Correct answer: A
Explanation
In vSphere with Tanzu, the Workload Network is essential for Kubernetes namespaces to operate. If the vSphere Distributed Switch lacks the required port group configurations, the namespaces cannot be created or function properly. This makes verifying and correcting the Distributed Switch setup a critical lifecycle activity in this scenario.
- A. Correct.
The vSphere Distributed Switch must have port groups configured correctly for the Workload Network, as this is critical for enabling communication between the Supervisor Cluster and Kubernetes namespaces.
- B. Incorrect.
While kubectl is required to interact with Kubernetes workloads, it is not directly related to the issue of namespace creation within vSphere with Tanzu.
- C. Incorrect.
Resource allocation for NSX-T Edge nodes is important for network functionality, but it is not directly related to the inability to create Kubernetes namespaces.
- D. Incorrect.
A valid vSphere with Tanzu license is required, but if a license issue existed, the Supervisor Cluster would not be configured successfully in the first place.
