A VKS upgrade failed with an error indicating that a new control plane node could not join the cluster due to a certificate mismatch. The administrator has verified that the certificate issue is resolved. What is the correct next step to complete the upgrade?

Retry the upgrade from the vCenter UI, which resumes from the last successful checkpoint

Manually re-run the failed node join command from the VKS CLI

Roll back the entire Supervisor Cluster to the previous VKS version before attempting the upgrade again

Rebuild the failed node from scratch and then restart the upgrade

A VKS upgrade fails with an error indicating that a control plane node is not responding. The administrator checks the node's status and finds that it is powered on but not healthy. What is the MOST appropriate diagnostic step?

Restart the upgrade to see if the node recovers

Check the node's system logs and VKS component logs for errors

Reboot the node to clear any temporary issues

Roll back the VKS to the previous version immediately

A VKS upgrade fails during the upgrade process. What is the recommended first step to safely restart the upgrade?

Re-initiate the upgrade from the vSphere Client, which resumes from the point of failure.

Power off all Supervisor Cluster VMs and then power them back on.

Roll back the VKS to the previous version and then start the upgrade again.

Delete the VKS and recreate it with the new version.

After rolling back a failed VKS upgrade, the administrator wants to confirm that the Supervisor Cluster is fully operational. Which check is the MOST important to perform?

Verify that the VKS version matches the previous version and that all control plane nodes are healthy

Check that the upgrade task shows as 'rolled back' in the vCenter UI

Ensure that the new VKS version is still available in the image store

Confirm that all workload namespaces are deleted

A VKS upgrade fails, and the administrator notices that the Supervisor Cluster's API server is intermittently unavailable. The logs show repeated 'connection refused' errors. The administrator suspects a control plane node is failing. What is the MOST appropriate diagnostic step to confirm this?

Check the health and logs of each control plane node from the vCenter UI

Restart the upgrade to see if the issue resolves itself

Roll back the VKS to the previous version immediately

Reboot the entire Supervisor Cluster to clear the connection issues
