You are asked to deploy an application that requires 20 GiB of storage. The cluster has a StorageClass named 'fast' that provisions network-attached storage. You create a PVC that requests 20 GiB and specifies storageClassName: fast. The pod that uses this PVC is scheduled on a node. What is the sequence of events that occurs?

The StorageClass creates the PV, but the PVC must be manually bound

The PVC binds to an existing PV with the same StorageClass, and the pod mounts it

The pod mounts the PVC directly, and the PV is created later

The StorageClass provisioner creates a PV, the PVC binds to it, and the pod mounts the PVC

Which component is responsible for actually creating the underlying storage resource when a StorageClass is used?

The CSI (Container Storage Interface) driver or in-tree provisioner specified in the StorageClass

In a StatefulSet, how is persistent storage typically associated with each Pod?

By defining a volumeClaimTemplates section in the StatefulSet spec

By using a single PersistentVolumeClaim that is shared by all Pods in the StatefulSet

By manually creating a PersistentVolume for each Pod before the StatefulSet is deployed

By using a hostPath volume that points to a unique directory on each node

What happens when a PersistentVolumeClaim (PVC) is created and a matching PersistentVolume (PV) is found?

The PVC and PV are bound to each other, and the PV's phase changes to 'Bound'

The PVC is assigned to a random PV, regardless of size or access mode

The PV is immediately deleted and recreated to match the PVC's specifications

The PVC is rejected because PVs must be created after PVCs

Your team wants to use a StorageClass that delays the creation of the persistent volume until a pod that uses the PVC is scheduled. This is to ensure the volume is created in the same zone as the pod. Which field should you set in the StorageClass?

volumeBindingMode: WaitForFirstConsumer
