How does tolerationSeconds affect a toleration for a NoExecute taint? Choose two.

  1. With it, the taint is ignored entirely
  2. With it, the node lifecycle controller evicts the Pod once the time elapses
  3. Without it, the Pod stays bound to the node indefinitely
  4. Without it, the Pod is evicted immediately
Show the answer

Answer: C. Without it, the Pod stays bound to the node indefinitely
B. With it, the node lifecycle controller evicts the Pod once the time elapses

A NoExecute toleration lasting forever omits tolerationSeconds; setting it bounds how long the Pod remains.
