   Your cluster runs on a cloud provider that offers multiple storage tiers. You need to create a StorageClass that provisions storage with a specific performance tier (e.g., SSD) and allows the volume to be deleted when the PVC is deleted. Which fields must you set in the StorageClass definition?

   • Aprovisioner and parameters (e.g., type=SSD) and reclaimPolicy: Delete
   • Bprovisioner and reclaimPolicy: Retain only
   • Cparameters only, no provisioner needed
   • DvolumeBindingMode: WaitForFirstConsumer and reclaimPolicy: Delete

   Your team has a StorageClass that uses a cloud provider's provisioner with reclaimPolicy: Retain. A developer creates a PVC, uses it in a pod, and then deletes the PVC. The PV is now in the Released state. The developer wants to reuse the same underlying storage for a new PVC. What must be done?

   • AThe PV will automatically become Available and bind to the new PVC
   • BManually delete the PV and create a new PV from the underlying storage, then create a new PVC
   • CChange the reclaimPolicy of the PV to Delete and delete the PVC again
   • DCreate a new PVC that references the same StorageClass; it will automatically bind to the Released PV
