2V0-21.23 Question 354
Select 3An administrator needs to update a Supervisor Cluster running on vSphere with Tanzu to the latest version. The cluster is configured with multiple namespaces and workloads. Before initiating the update, which steps must the administrator perform to ensure a successful update?
- A
Verify that sufficient resources such as CPU, memory, and storage are available for the update process.
- B
Backup the Supervisor Cluster and all associated workloads before starting the update.
- C
Manually upgrade the Kubernetes version on each namespace before upgrading the Supervisor Cluster.
- D
Check the VMware Compatibility Guide (VCG) to ensure the target vSphere version supports the desired Supervisor Cluster update.
- E
Disable DRS (Distributed Resource Scheduler) during the update process to prevent workload migrations.
Show answer and explanation
Correct answers: A, B, D
Explanation
Updating a Supervisor Cluster involves careful planning and preparation. Verifying resource availability ensures the update process can complete without interruptions. Backing up the Supervisor Cluster and workloads protects against potential failures. Checking the VMware Compatibility Guide ensures compatibility between the vSphere version and the desired Supervisor Cluster version. These steps help ensure a smooth and successful update process.
- A. Correct.
Correct. Ensuring sufficient resources are available is critical to avoid failures during the update process. If resources are constrained, the update may fail or cause disruption to workloads.
- B. Correct.
Correct. Backing up the Supervisor Cluster and workloads ensures that the administrator can restore them in case the update fails or issues arise during the process.
- C. Incorrect.
Incorrect. The Kubernetes version is automatically managed as part of the Supervisor Cluster update process. Manual intervention is not required here.
- D. Correct.
Correct. The VMware Compatibility Guide (VCG) must be checked to confirm that the target vSphere version supports the intended Supervisor Cluster version, as version mismatches can cause compatibility issues.
- E. Incorrect.
Incorrect. Disabling DRS is not required during the update process. In fact, keeping DRS enabled can help manage resource distribution during the update.
