1. A Kubernetes administrator needs to provision storage automatically for applications deployed in the cluster. Developers should not need to manually create PersistentVolumes. What should the administrator configure?

A Create PersistentVolumes manually for each application before deploying.
B Create a StorageClass that references an appropriate provisioner.
C Create a ConfigMap that maps volume names to storage paths.
D Use emptyDir volumes in each pod specification.

2. A company's cluster has a StorageClass named 'fast-ssd' set as the default. A developer creates a PVC without specifying a storageClassName field. Which StorageClass will the PVC use?

A The PVC will use 'fast-ssd' because it is the default StorageClass.

C The PVC will use the StorageClass configured for its namespace.

3. A Kubernetes administrator observes that a PersistentVolumeClaim remains in the 'Pending' state after creation. The StorageClass used has volumeBindingMode set to 'WaitForFirstConsumer'. What is the expected behavior?

A The PVC is stuck due to a misconfiguration and the administrator should re-create it.
B The PVC will never bind and must be deleted and re-created with Immediate binding mode.
C The PVC will remain Pending until a Pod referencing it is scheduled, at which point the volume is provisioned.
D The PVC will bind immediately once the provisioner creates the PersistentVolume.

B Delete
C Recycle
D Archive
