An administrator adds a NoExecute taint to a node that is already running Pods. Which two things happen? Choose two.

  1. Pods without a matching toleration are evicted
  2. All Pods are left running until they restart
  3. No new Pod without a matching toleration is scheduled there
  4. The node is marked unschedulable
Show the answer

Answer: A. Pods without a matching toleration are evicted
C. No new Pod without a matching toleration is scheduled there

NoExecute affects both the future and the present: it keeps intolerant Pods off and throws off the ones already there. NoSchedule would do only the former.
