CKA study material · question 189 of 1000

A static Pod must survive resource pressure. Why can it not use priorityClassName?

  1. The kubelet strips the field from mirror Pods
  2. Static Pods do not support that field, so priority is set directly
  3. PriorityClasses are namespaced and static Pods are not
  4. Static Pods always have priority zero
Show the answer

Answer: B. Static Pods do not support that field, so priority is set directly

Static Pods do not support priorityClassName, so the priority field is set on the Pod itself.
