   A DevOps team runs a stateful application on VMware vSphere with Tanzu using a StorageClass backed by vSphere CSI. The application's PVC was created with a StorageClass that has `allowVolumeExpansion: true`. The team needs to increase the PVC's capacity from 50 Gi to 100 Gi. The underlying vSphere datastore has ample free space. Which action will successfully expand the persistent volume?

   • AEdit the StorageClass and change `allowVolumeExpansion` to true, then modify the PVC.
   • BCreate a new PVC with 100Gi and manually bind it to the existing PV.
   • CDelete the PVC and recreate it with a new size of 100Gi.
   • DEdit the PVC and change `spec.resources.requests.storage` from 50Gi to 100Gi, then apply the change.

   A company runs a critical application in a vSphere with Tanzu environment. The application uses PVCs with data that must be recoverable within 4 hours (RTO) and with a maximum data loss of 1 hour (RPO). The backup window is limited to 2 hours nightly. The administrator is evaluating backup strategies. Which strategy best meets the RPO and RTO requirements?

   • AUse Velero with scheduled backups every hour and store backups in a separate object storage bucket.
   • BUse Velero with a single nightly backup and rely on the underlying storage replication.
   • CUse Velero with backups every 6 hours and store them in the same cluster.
   • DUse Velero with continuous backups using the `--snapshot-volumes` flag.
