When a PersistentVolumeClaim references a StorageClass, what is created and who provisions it?

• A. A PersistentVolume is created manually by admin
• B. A PersistentVolume is created by the platform according to the StorageClass provisioning parameters
• C. A Deployment is created
• D. A Service is created

Answer: (B)

When a PVC references a StorageClass, the cluster uses dynamic provisioning to create storage on demand. The StorageClass defines a provisioner and parameters for the underlying storage. The cluster’s storage provisioner creates a new PersistentVolume that matches the PVC’s requested size and access requirements, and this PV is created by the platform according to those parameters. The PVC then binds to that newly created PV. Deployment or Service objects are unrelated to this storage process; they pertain to running and exposing applications, not to provisioning storage.
