2V0-21.23 Question 350
Select 2You are a VMware administrator tasked with managing the lifecycle of a vSphere with Tanzu environment. During a routine review, you discover that the Kubernetes Control Plane Node VM is running an outdated version and requires an upgrade. What steps must you take to successfully upgrade the vSphere with Tanzu Kubernetes Control Plane?
- A
Update the vSphere Distributed Switch (vDS) version in use by the Tanzu environment.
- B
Upgrade the Supervisor Cluster using the vSphere Lifecycle Manager (vLCM).
- C
Update the Tanzu Kubernetes Grid (TKG) templates to the latest version.
- D
Verify the compatibility of the new Kubernetes version with the vSphere with Tanzu version.
- E
Use the kubectl CLI tool to manually apply updates to the Kubernetes Control Plane Node.
Show answer and explanation
Correct answers: B, D
Explanation
Upgrading the Kubernetes Control Plane Node in a vSphere with Tanzu environment requires careful planning and execution. The Supervisor Cluster must be upgraded using vSphere Lifecycle Manager (vLCM), and compatibility between the new Kubernetes version and the vSphere with Tanzu environment must be verified to avoid disruptions. Other options, such as updating vDS or manually applying updates, are either unnecessary or unsupported in this context.
- A. Incorrect.
Updating the vSphere Distributed Switch (vDS) version is not required for upgrading the Kubernetes Control Plane Node. It is only necessary if the vDS version is incompatible with the vSphere with Tanzu environment.
- B. Correct.
Upgrading the Supervisor Cluster using the vSphere Lifecycle Manager (vLCM) is a required step in the lifecycle management of the vSphere with Tanzu environment, as it ensures the Kubernetes Control Plane is updated properly.
- C. Incorrect.
Updating the Tanzu Kubernetes Grid (TKG) templates is important for deploying new workloads but is not directly related to upgrading the existing Kubernetes Control Plane Node.
- D. Correct.
Verifying the compatibility of the new Kubernetes version with the vSphere with Tanzu version is critical to ensure that the upgrade does not introduce compatibility issues.
- E. Incorrect.
Using the kubectl CLI tool to apply updates manually to the Kubernetes Control Plane Node is not recommended or supported in the vSphere with Tanzu lifecycle. Updates must be managed through vSphere tools.
