   A team is rolling out a new version of a microservice to GKE. The new version occasionally fails to initialize correctly, and when it does, it returns HTTP 500 errors. The team wants to ensure that during the rollout, pods that are not ready do not receive traffic from the Service. Which configuration should they add to the deployment?

   • AA startup probe that checks the /healthz endpoint and delays the readiness probe until the pod is ready.
   • BA liveness probe that checks the /healthz endpoint and restarts the container on failure.
   • CA Service with a selector that matches only pods with the 'ready=true' label.
   • DA readiness probe that checks the /healthz endpoint and returns success only when the pod is fully initialized.

   A developer is deploying a stateless web application to GKE. The application takes a few seconds to initialize and load configuration before it can serve traffic. During this startup period, the application process is running but not yet ready to accept requests. The developer wants to ensure that the pod is not added to the Service's endpoints until it is fully ready, and that the pod is restarted if the process becomes unresponsive after startup. Which set of probes should be configured in the deployment manifest?

   • AOnly a liveness probe with an initialDelaySeconds that covers the startup time.
   • BA startup probe with an initialDelaySeconds that covers the startup time, and a liveness probe with the same periodSeconds.
   • CA readiness probe with an initialDelaySeconds that covers the startup time, and a liveness probe with a longer periodSeconds.
   • DOnly a readiness probe with a short periodSeconds to quickly detect readiness.
