What is the purpose of a rolling update in a Deployment?

To delete all old pods before creating new ones

To scale the number of replicas

To update the Service configuration

To update pods incrementally without downtime

What happens when a container exceeds its memory limit?

The container is terminated, possibly with an OOMKilled status

The container is restarted with a new limit

The pod is evicted from the node

A web application occasionally enters a deadlock state where it stops responding to HTTP requests but the process remains alive. The team wants Kubernetes to automatically restart the container when this happens. Which configuration should they add to the pod spec?

A resource limit on memory that causes the container to be OOM-killed when it exceeds the limit.

A liveness probe that checks an HTTP endpoint and restarts the container when the probe fails.

A startup probe that checks an HTTP endpoint and delays other probes until the app is ready.

A readiness probe that checks an HTTP endpoint and removes the pod from Service endpoints when it fails.

How can you roll back a Deployment to a previous revision?

Use the kubectl rollout undo command

Delete the Deployment and recreate it

Edit the Deployment's image and apply it
