   A microservice depends on a database. The team wants Kubernetes to stop sending traffic to the pod when the database is unreachable, but not restart the pod. They also want the pod to be restarted if the application process hangs. Which probe configuration should they use?

   • AOnly use a readiness probe that checks the database connectivity.
   • BReadiness probe that checks the database connectivity, and a liveness probe that checks the process health.
   • CUse the same health endpoint for both liveness and readiness probes.
   • DLiveness probe that checks the database connectivity, and a readiness probe that checks the process health.
