A team runs a stateful application on a node with other workloads. The application sometimes consumes excessive memory, causing the node to run out of memory and other pods to be evicted. They want to prevent this from affecting other workloads while ensuring the application has enough memory to run normally. What should they configure?

A memory limit equal to the application's typical usage and no request.

A memory request equal to the application's typical usage and a memory limit higher than typical usage.

A memory request higher than typical usage and no limit.

A memory limit lower than typical usage.

What happens to a pod when its readiness probe fails?

It is removed from the Service endpoints

A Deployment runs a microservice that needs to load a large configuration file at startup. During this loading period, the service cannot handle requests. The team wants to ensure that the Service does not route traffic to the pod until it is fully ready. Which probe should they configure?

A startup probe that checks a startup endpoint.

A liveness probe that checks a health endpoint.

A resource request that guarantees CPU during startup.

A readiness probe that checks a readiness endpoint.
