A company runs a web frontend that connects to a backend database. During a database outage, the frontend process stays alive but returns HTTP 503 errors. The team wants the Service to stop sending traffic to the affected pod while the database is down, but does NOT want the pod restarted. Which probe configuration achieves this?

livenessProbe with httpGet path /ready and port 8080, failureThreshold: 3

readinessProbe with httpGet path /ready and port 8080, failureThreshold: 3

readinessProbe with tcpSocket port 8080, failureThreshold: 3

startupProbe with httpGet path /ready and port 8080, failureThreshold: 3

What is the primary purpose of a liveness probe in a Kubernetes pod?

To scale the number of pod replicas based on the container's resource usage.

To restart a container that has become unhealthy or deadlocked.

To control whether the pod receives network traffic from services.

To determine when a container has finished starting up so the liveness probe can begin.

Which kubectl command is used to view recent events for a pod, such as probe failures or container restarts?

kubectl get events --field-selector involvedObject.name=

A team runs a web app with a readiness probe that checks /ready on port 8080. The probe currently has periodSeconds: 10 and failureThreshold: 3. The team notices that the pod is marked NotReady after a single transient failure that lasts only 2 seconds. They want to make the probe more tolerant of transient failures. Which change should they make?
