What is the purpose of setting resource requests in a Kubernetes pod spec?

To define the container's startup command.

To reserve a minimum amount of CPU and memory for the container.

To limit the maximum CPU and memory the container can use.

To specify the number of replicas for the Deployment.

What is the purpose of the `apiVersion` field in a Kubernetes manifest?

To specify the version of the Kubernetes API used to create the resource.

To set the Kubernetes cluster version required to run the manifest.

To indicate the application version for rollout tracking.

To define the version of the container image to deploy.

How are secrets typically stored and accessed in Kubernetes?

As environment variables defined in the Dockerfile.

As entries in the ConfigMap object.

As plaintext files in the container image.

As base64-encoded objects in the cluster, mounted into pods as volumes or environment variables.

A team is deploying a multi-tier application: a frontend, a backend, and a database. They want to isolate the database from the frontend and backend for security, and they want to be able to apply different resource quotas to each tier. Which Kubernetes feature should they use?

Use different Deployments for each tier in the same namespace

Use different Services for each tier in the same namespace

Create a separate namespace for each tier

Use different Pods for each tier in the same namespace

A team is deploying an application to Kubernetes that needs a database password and an API endpoint URL. They want to avoid hardcoding these values in the container image and avoid storing the password in plain text in the Deployment manifest. Which approach should they use?

Embed the password and URL as environment variables in the Dockerfile using ENV instructions

Store the password in a Kubernetes Secret and the URL in a ConfigMap, then reference both in the Deployment manifest

Store both the password and URL in a Kubernetes Secret and reference it in the Deployment manifest

Store both the password and URL in a ConfigMap and reference it in the Deployment manifest
