A records app must keep uploaded PDFs across Pod restarts and reschedules to other nodes. Which volume approach should the developer choose?
Select an answer to reveal the explanation.
Short Explanation
If the filing cabinet must still be there after the office moves floors, you need real persistent storage—a PVC—not a notepad that vanishes with the Pod (emptyDir).
Full Explanation
PersistentVolumeClaims bind application Pods to persistent storage that survives Pod restart and reschedule (subject to access mode and storage backend). emptyDir and the container writable layer do not provide durable multi-node persistence. hostPath ties data to a specific node and is a poor portable default for user uploads.
