20+ practice questions focused on Storage And Persistent Volumes — one of the most tested topics on the Red Hat Certified OpenShift Administrator (EX280, OpenShift Container Platform 4.14+) (EX280) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Storage And Persistent Volumes PracticeA developer requests a PersistentVolumeClaim using ReadWriteMany access mode. Which default storage type in a standard AWS ODF (OpenShift Data Foundation) deployment natively supports RWX?
Explanation: The CephFS CSI driver (openshift-storage.cephfs.csi.ceph.com) is the only default storage class in an AWS OpenShift Data Foundation deployment that natively supports ReadWriteMany (RWX) access mode. CephFS is a POSIX-compliant shared filesystem that allows multiple pods on different nodes to mount and write to the same volume simultaneously. RBD (RADOS Block Device) and EBS are block storage, which only support ReadWriteOnce (RWO) or ReadOnlyMany (ROX), not RWX.
A user creates a VolumeSnapshot and notices that the resulting VolumeSnapshotContent status is marked as readyToUse: false. What is the most likely cause?
Explanation: A VolumeSnapshotContent reports readyToUse: false while the CSI driver is still completing the snapshot operation against the backend storage. If the source PVC has active writes, the storage system must quiesce or flush data before the snapshot can be marked consistent and ready, so the status remains false until synchronization finishes. Once the CSI CreateSnapshot call returns successfully, the controller flips readyToUse to true.
An administrator needs to provision persistent storage dynamically using an NFS server. Which provisioner is required in the StorageClass definition since OpenShift removed the in-tree NFS provisioner?
Explanation: The correct provisioner is sig-storage.k8s.io/nfs-subdir-external-provisioner. OpenShift removed the in-tree NFS provisioner, so dynamic provisioning for NFS requires an external provisioner. The nfs-subdir-external-provisioner is a Kubernetes SIG-Storage project that creates subdirectories on an existing NFS server, and its provisioner name must be specified in the StorageClass as sig-storage.k8s.io/nfs-subdir-external-provisioner. This provisioner is deployed separately and watches for PersistentVolumeClaims that reference this StorageClass.
You are creating a StorageClass and want to ensure that PersistentVolumes created by it are only deleted when the PVC is explicitly deleted, rather than retaining them. Which parameter should you set?
Explanation: The reclaimPolicy field in a StorageClass controls what happens to the underlying PV when its PVC is deleted. Setting it to Retain ensures data persistence.
Which object acts as a cluster-scoped abstraction that defines and parameterizes the type of storage (such as provisioner, parameters, and reclaim policy) that can be dynamically provisioned in OpenShift?
Explanation: A StorageClass defines the provisioner and parameters used to dynamically provision PersistentVolumes.
