CV0-004 Deployment Practice Question
A cloud engineer needs to deploy a containerized application on Amazon EKS. The application requires a persistent storage volume that can be dynamically provisioned. Which Kubernetes resource should be used to request storage?
⚠ Common exam trap
The exam often tests the distinction between a PersistentVolume (the actual storage resource) and a PersistentVolumeClaim (the request for storage), leading candidates to mistakenly select PV when the question asks for the resource that 'requests' storage.

Correct answer & explanation
✓
PersistentVolumeClaim
A PersistentVolumeClaim (PVC) is the correct Kubernetes resource to request storage because it acts as a request for storage by a pod, specifying size, access modes, and optionally a StorageClass. In Amazon EKS, a PVC can trigger dynamic provisioning of an EBS or EFS volume via a StorageClass, decoupling the storage request from the underlying PersistentVolume. This allows the cloud engineer to deploy the containerized application without manually pre-provisioning storage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
PersistentVolume
Why it's wrong here
PersistentVolume is the actual storage resource, not a request.
- ✓
PersistentVolumeClaim
Why this is correct
PVC is a request for storage by a pod.
- ✗
StorageClass
Why it's wrong here
StorageClass defines the type of storage, but doesn't request it.
- ✗
ConfigMap
Why it's wrong here
ConfigMap stores configuration data, not storage.
