Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
spec.dataSource referencing the VolumeSnapshot
Why this is correct
Correct. Setting the dataSource to point to an existing VolumeSnapshot instructs the dynamic provisioner to provision the new PVC using the snapshot data.
- ✗
metadata.annotations['snapshot.storage.kubernetes.io/restore']
Why it's wrong here
Incorrect. Snapshot restorations are controlled through spec.dataSource rather than metadata annotations.
- ✗
spec.resources.requests.storage matching the exact snapshot block ID
Why it's wrong here
Incorrect. Storage requests specify capacity size, not backend identifiers.
- ✗
spec.volumeName matching the UUID of the snapshot storage backend
Why it's wrong here
Incorrect. spec.volumeName is used to bind directly to a pre-existing PV, not to restore from a snapshot.
