CKA study material · question 514 of 1000

A node goes unreachable at 10:00 and its Ready condition is set to Unknown immediately. With default settings, when does the node controller first request eviction of its Pods?

  1. At 10:00:05, one node-monitor-period later
  2. At 10:05
  3. At 10:00:30, after the default grace period
  4. Not at all until an administrator deletes the Node
Show the answer

Answer: B. At 10:05

The node controller waits five minutes by default between marking a node Unknown and submitting the first eviction, which gives a briefly partitioned node time to come back.
