CKA study material · question 871 of 1000

A node goes unreachable. kubectl describe pod on one of its Pods shows a toleration for node.kubernetes.io/unreachable with tolerationSeconds 300. What does that govern?

  1. How long the kubelet waits before restarting the containers
  2. How long the Pod stays bound before eviction is requested
  3. How long the scheduler waits before placing a replacement
  4. How long the node controller waits before deleting the Node
Show the answer

Answer: B. How long the Pod stays bound before eviction is requested

Pods carry default tolerations for not-ready and unreachable with tolerationSeconds of 300, which is the delay before the Pods of a lost node are evicted.
