CV0-004 Practice Question: Deploying a stateful application that requires…
A company is deploying a stateful application that requires persistent storage. They are using Kubernetes. Which resource should they create to ensure data persists across pod restarts?
⚠ Common exam trap
It's easy for candidates to confuse a Deployment's ability to manage replicas with data persistence, overlooking that a Deployment alone does not guarantee storage survival across pod restarts without an explicit PVC.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
PersistentVolumeClaim
A PersistentVolumeClaim (PVC) is the correct resource because it abstracts the underlying storage details and allows a pod to request persistent storage that survives pod restarts. When a pod is recreated, the PVC ensures the same volume is reattached, preserving application state. This is essential for stateful applications in Kubernetes, as pods are ephemeral by default.
