A Kubernetes cluster uses a StorageClass with `allowVolumeExpansion: false`. An application requires more storage, and the administrator wants to enable expansion for the existing PVCs. The underlying storage provider supports online expansion. What is the correct sequence of actions?

Edit the PVC to increase the requested size; the StorageClass setting is irrelevant.

Create a new StorageClass with `allowVolumeExpansion: true` and then edit the PVC to use the new StorageClass.

Delete the PVC and recreate it with a larger size using the same StorageClass.

Edit the StorageClass to set `allowVolumeExpansion: true`, then edit the PVC to increase the requested size.

What does Velero use to back up persistent volume data?

Replicating the volume to another storage class

Copying the entire disk image to the backup storage

Exporting the volume contents to a tar file stored on the node

Volume snapshots via the storage provider's snapshot API

An administrator needs to provide a pre-existing NFS share to a Kubernetes workload in a vSphere with Tanzu cluster. The share is already formatted and contains data. The administrator wants to make this share available to a specific namespace. What is the correct approach?

Create a PersistentVolume with `persistentVolumeReclaimPolicy: Retain` and a `claimRef` to a PersistentVolumeClaim in the target namespace.

Use a hostPath volume in the pod spec to mount the NFS share directly.

Create a StorageClass with `provisioner: nfs` and then create a PVC that references it.

Create a PersistentVolumeClaim with `storageClassName: ""` and let it bind to any available PV.

What is the primary goal of a backup and restore strategy?

To store backups only on-premises for security.

To minimize the cost of storage by using the cheapest backup solution.

To ensure data can be recovered within the organization's recovery point objective (RPO) and recovery time objective (RTO).

To back up all data as frequently as possible.
