CKA study material · question 669 of 1000

A Pod tolerates a NoExecute taint and sets tolerationSeconds to 3600. The taint is applied at noon and removed at 12:30. What happens to the Pod?

  1. It is evicted at 13:00 regardless
  2. It is evicted at 12:30 when the taint is removed
  3. It is evicted immediately, since tolerationSeconds applies only to NoSchedule
  4. It is not evicted at all
Show the answer

Answer: D. It is not evicted at all

tolerationSeconds starts a clock when the taint appears; removing the taint before it expires cancels the eviction entirely.
