CKA study material · question 997 of 1000

The node.kubernetes.io/out-of-service taint is applied to a node confirmed powered off. Which two things follow? Choose two.

  1. Pods without a matching toleration are force-deleted
  2. The Node object is deleted automatically
  3. Volume detach operations happen immediately
  4. The taint is removed once the node returns
Show the answer

Answer: A. Pods without a matching toleration are force-deleted
C. Volume detach operations happen immediately

The taint force-deletes intolerant Pods and detaches their volumes at once so workloads recover elsewhere. The Node object stays, and the administrator must remove the taint by hand.
