   A company runs a stateful application in containers. They need to ensure that data persists across container restarts and that the application can be scaled horizontally. They are considering using a container orchestration platform. Which storage and scaling approach should they use to meet these requirements?

   • AUse persistent volumes with a StatefulSet and scale by adding replicas that share the persistent volume.
   • BUse a StatefulSet with persistent volumes and scale by adding replicas that each have their own persistent volume claim.
   • CUse persistent volumes with a Deployment and scale by adding replicas, each with its own persistent volume claim.
   • DUse ephemeral container storage and rely on the orchestration platform to restart containers.

   A company wants to implement continuous delivery for a mobile app. They have a CI pipeline that builds and runs unit tests. However, they are concerned about releasing to production because of regulatory compliance checks that require manual sign-off. They also want to ensure that the exact binary tested is the one deployed. Which approach best satisfies these constraints?

   • AStore the build artifact in an artifact repository and have the deployment pipeline retrieve that exact artifact after manual compliance approval.
   • BDeploy to production directly from the CI pipeline after unit tests pass.
   • CAutomate the compliance checks in the pipeline and deploy without manual approval.
   • DRebuild the application in the deployment pipeline to ensure it is fresh.

   In Git, what is the purpose of a branch?

   • ATo lock files so only one developer can edit them at a time.
   • BTo create an independent line of development that can be merged back later.
