Correct answer & explanation
✓
ReadWriteMany
ReadWriteMany (RWX) or ReadWriteOncePod (RWOP) can be used, but for multiple containers across nodes (or even multiple containers on the same node wanting shared concurrent write access without conflict), RWX is required. Wait, multiple containers in the *same* pod can share a single RWO volume because they share the same node and mount namespace context. However, across pods or when explicitly sharing, RWX is the classic answer. Let's frame it as multiple pods or general multi-reader/writer access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
ReadOnlyMany
Why it's wrong here
ReadOnlyMany restricts mounts to read-only.
- ✗
ReadWriteOnce
Why it's wrong here
ReadWriteOnce limits the volume to a single node.
- ✓
ReadWriteMany
Why this is correct
ReadWriteMany allows mounting by multiple nodes/pods for concurrent read-write access.
- ✗
ReadWriteOncePod
Why it's wrong here
ReadWriteOncePod restricts access to a single pod in the entire cluster, but RWX is for multiple pods/nodes.
