recursiveReadOnly is set to Enabled on a volume mount. Which two conditions must hold? Choose two.

  1. readOnly must be true
  2. mountPropagation must be Bidirectional
  3. mountPropagation must be unset or None
  4. The container must be privileged
Show the answer

Answer: A. readOnly must be true
C. mountPropagation must be unset or None

Enabled requires readOnly true and propagation unset or None, plus a recent enough kernel and runtime; it fails outright if any of those is missing, whereas IfPossible falls back.
