For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
hostPath
Why it's wrong here
hostPath mounts a file or directory from the host node's filesystem, which is not specific to the pod.
- ✓
emptyDir
Why this is correct
emptyDir provides a shared volume for containers within the same pod.
