After setting failSwapOn to false, workloads still get no swap. What else must change?

  1. memorySwap must be added to each Pod spec
  2. The node must be relabelled as swap-enabled
  3. swapBehavior must be changed from its NoSwap default
  4. The container runtime must be restarted
Show the answer

Answer: C. swapBehavior must be changed from its NoSwap default

failSwapOn only lets the kubelet start; swap access needs swapBehavior set to something other than NoSwap.
