Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
PersistentVolume: A piece of storage in the cluster provisioned by an administrator.
The correct matches are: PersistentVolume is a cluster storage resource, PersistentVolumeClaim is a user request for storage, and StorageClass defines storage classes. Two common confusions are swapping PV and PVC definitions.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
PersistentVolume: A piece of storage in the cluster provisioned by an administrator.
Why this is correct
PersistentVolume is a cluster resource that represents a storage volume, independent of any pod.
PersistentVolumeClaim: A request for storage by a user that binds to a PersistentVolume.
Why this is correct
PersistentVolumeClaim is a request for storage by a user, which binds to a PersistentVolume matching the requirements.
StorageClass: Defines the type of storage, including provisioner and parameters, that a PersistentVolumeClaim can request.
Why this is correct
StorageClass is a way to describe different classes of storage, enabling dynamic provisioning of PersistentVolumes.
PersistentVolume: A request for storage by a user that binds to a PersistentVolume.
Why it's wrong here
This description actually refers to a PersistentVolumeClaim, not a PersistentVolume.
PersistentVolumeClaim: A piece of storage in the cluster provisioned by an administrator.
Why it's wrong here
This description actually refers to a PersistentVolume, not a PersistentVolumeClaim.
