A Service has no EndpointSlices at all. What does that point to?

  1. The selector matches no ready Pods, usually a label mismatch
  2. The cluster IP is out of range
  3. The Service's protocol is unsupported
  4. kube-proxy is not running
Show the answer

Answer: A. The selector matches no ready Pods, usually a label mismatch

No EndpointSlices means the selector found nothing; that is a labelling problem, not a networking one.
