   A team is designing a CI/CD pipeline for a web application. They want to catch low-level logic errors as quickly as possible, but they also want to verify that the application works correctly with its database and external APIs before deployment. Which test strategy should they implement?

   • ARun unit tests in the CI pipeline and run integration tests in the CD pipeline before deployment to staging.
   • BRun all tests in a single stage at the end of the pipeline to minimize the number of pipeline stages.
   • CRun only end-to-end tests in the CI pipeline to cover all functionality in one pass.
   • DRun integration tests in the CI pipeline and unit tests only in the CD pipeline after deployment.

   A team uses a Git repository to manage both application code and Terraform infrastructure definitions. They want to ensure that a change to the infrastructure does not break the application that depends on it. What is the most effective way to use version control to achieve this?

   • AUse Git submodules to link the application repository to the infrastructure repository.
   • BUse a monorepo with a CI pipeline that runs application tests against the infrastructure changes in the same commit.
   • CKeep application code and infrastructure in separate repositories and manually coordinate releases.
   • DTag every infrastructure change with a version number and require the application to reference that version.

   A company is migrating a monolithic application to microservices. They want to ensure that each microservice can be built, tested, and deployed independently. Which cloud-native practice best supports this goal?

   • AUse infrastructure as code to define the entire application as one large Terraform configuration.
   • BDeploy all microservices as a single unit using a shared virtual machine to reduce overhead.
   • CUse a single CI/CD pipeline that builds and tests all microservices together.
   • DContainerize each microservice and use a CI/CD pipeline that builds and tests each container independently.
