CKA study material · question 515 of 1000

An operator wants the control plane to notice node failures faster. Which kube-controller-manager flag controls how often each node's state is examined?

  1. --node-eviction-rate
  2. --node-status-update-frequency
  3. --node-monitor-period
  4. --unhealthy-zone-threshold
Show the answer

Answer: C. --node-monitor-period

--node-monitor-period, five seconds by default, sets how often the node controller checks each node. --node-status-update-frequency is a kubelet flag on the reporting side, and the others govern eviction behaviour.
