An NFS server supports many writers but a PV backed by it is read-only. Which two statements explain this? Choose two.

  1. Access modes describe what that specific PV supports
  2. The StorageClass overrides a PV's access modes
  3. A PV's modes may be narrower than the storage system's capability
  4. NFS PVs are always read-only in Kubernetes
Show the answer

Answer: A. Access modes describe what that specific PV supports
C. A PV's modes may be narrower than the storage system's capability

Each PV gets its own access modes describing that volume, which need not match everything the backend can do.
