Container and Container Orchestration

Which of the following statements regarding dynamically provisioned PersistentVolumes (PVs) are true?

Choose two
  • A You do not need to manually create PVs.
  • B The reclaim policy for these PVs can only be Delete.
  • C If no StorageClass is specified in the PersistentVolumeClaim (PVC), the system switches to a static PV.
  • D This feature depends on StorageClasses.
Explanation

Dynamic provisioning automatically creates storage and its PersistentVolume when a PersistentVolumeClaim requests an applicable StorageClass, eliminating manual PV pre-creation. StorageClass is the mechanism that defines the provisioner and parameters used for dynamic provisioning. The reclaim policy is configurable through the StorageClass and defaults to Delete; it is not limited to that value. A PVC without storageClassName can use a default StorageClass rather than becoming static provisioning.
