Pod Health — Certified Kubernetes App Developer (CKAD) Practice Questions
Pod health in Kubernetes encompasses the combination of liveness probes, readiness probes, and startup probes that together determine whether a container is alive, ready to receive traffic, and finished with its initialization sequence. The CKAD exam tests candidates' ability to distinguish these three probe types and apply them correctly so that Kubernetes can route traffic and restart containers based on accurate health signals. Understanding pod health is also essential for interpreting why a Pod may be running but still excluded from a Service's endpoint list.
