EX280 Storage And Persistent Volumes Practice Question
A developer deploys a pod with an emptyDir volume. The application running inside writes temporary files. What happens to these files when the container crashes and restarts within the same pod?
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
✓
The files are preserved because emptyDir lifetime is tied to the pod, not individual containers.
An emptyDir volume survives container crashes and restarts; it is only deleted when the pod itself is removed from the node.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The files are backed up to the cluster control plane automatically.
Why it's wrong here
emptyDir is local scratch storage and is never backed up to the control plane.
- ✓
The files are preserved because emptyDir lifetime is tied to the pod, not individual containers.
Why this is correct
Container restarts do not clear emptyDir storage; only pod termination does.
- ✗
The files are deleted immediately because the container filesystem is ephemeral.
Why it's wrong here
While the container's root filesystem is ephemeral and reset on restart, an emptyDir volume mounted into the container persists across container restarts within the same pod.
- ✗
The volume is unmounted and reattached via the CSI driver.
Why it's wrong here
emptyDir uses local node storage (either disk or tmpfs) and does not involve CSI volume attachment workflows.
