Liveness Probe — Certified Kubernetes App Developer (CKAD) Practice Questions
A liveness probe is a Kubernetes health check configured on a container that tells the kubelet when to restart a container that has become unresponsive or entered a broken state, using HTTP, TCP, or exec-based checks. On the CKAD exam, candidates must be able to write correct probe configurations in YAML, including setting initialDelaySeconds, periodSeconds, and failureThreshold appropriately for the application. Misconfigured liveness probes are a common source of crash loops in production, so the exam tests both syntax knowledge and conceptual understanding of when to use them versus readiness probes.
