An application requires a persistent volume that can be expanded by updating the PVC's size. The cluster uses a StorageClass that was created with allowVolumeExpansion: false. The team needs to enable expansion for new PVCs. What should they do?

Use kubectl scale pvc --size=20Gi to expand the PVC.

Modify the PV's capacity field directly to increase the size.

Create a new PVC with a larger size request and delete the old PVC.

Edit the existing StorageClass and set allowVolumeExpansion: true, then create new PVCs using that StorageClass.

A company has a StorageClass with reclaimPolicy: Delete. A critical PVC is accidentally deleted. The team realizes the PV is still present in the cluster. What is the most likely reason?

The reclaimPolicy was changed to Retain after the PVC deletion.

The PV is in the Released phase and will be deleted later.

The PV was not dynamically provisioned; it was statically created.

The StorageClass was deleted before the PVC.

What must be true for a PVC to be resized when its StorageClass has allowVolumeExpansion enabled?

The PVC must be deleted and recreated.

The pod using the PVC must be restarted.

The PVC must be in the Pending state.

The underlying storage provider must support volume expansion.

What is the effect of the Retain reclaim policy on a PV after its PVC is deleted?

The PV remains in the Released state and its data is preserved.

The PV is immediately available for a new PVC to bind.

The PV is automatically deleted along with the underlying storage.

The PV is moved to the Failed state.

Implement Storage Classes and Dynamic Volume Provisioning CKA Practice Questions (Page 3)

Part of the Storage domain, which accounts for 10% of the CKA exam. Linux Foundation does not publish an official question count, but from its 120-minute exam (~50–80 total, ~5–8 in this domain), expect 2–3 from this objective — we provide 25 practice questions to prepare you well beyond it.
