CKA study material · question 617 of 1000

A namespace has a ResourceQuota covering requests.cpu. A developer submits a Pod with no CPU request or limit at all. What is the likely outcome?

  1. The Pod is admitted and counted as consuming zero CPU
  2. The Pod is admitted but never scheduled
  3. Admission is refused because the Pod declares neither requests nor limits for a quota'd resource
  4. The quota is ignored for Pods with no resource fields
Show the answer

Answer: C. Admission is refused because the Pod declares neither requests nor limits for a quota'd resource

Where a quota covers cpu or memory, every new Pod must specify requests or limits for that resource or the control plane may reject it; a LimitRange supplying defaults is the usual remedy.
