A company has a Kubernetes cluster with multiple microservices. They want to expose a web frontend service to the public internet on a specific hostname (e.g., app.example.com) and route traffic to the correct service based on the URL path. Which Kubernetes resources should they use?

An Ingress resource with rules for the hostname and path, backed by a ClusterIP Service for the frontend

A Service of type LoadBalancer for the frontend, and an Ingress resource with rules for the hostname and path

A Service of type ExternalName for the frontend, and an Ingress resource with rules for the hostname and path

A Service of type NodePort for the frontend, and an Ingress resource with rules for the hostname and path

A team is deploying an application that reads configuration from environment variables. They have a mix of sensitive and non-sensitive settings. They want to minimize the risk of exposing secrets in the cluster and also make it easy to update non-sensitive settings without redeploying. Which approach best meets these requirements?

Store sensitive settings in a Secret and non-sensitive settings in a ConfigMap, and reference both in the Deployment

Store all settings in a single Secret and reference it in the Deployment

Embed all settings in the Docker image as environment variables

Store all settings in a single ConfigMap and reference it in the Deployment

In a CI/CD pipeline, what is the typical purpose of the build stage?

To deploy the application to production immediately.

To compile code, run tests, and produce a deployable artifact such as a Docker image.

To monitor the application's runtime performance.

To roll back the application to a previous version.
