Deployment

1. A development team wants to fully automate their release process so that every code change that passes all automated tests is automatically released into production without manual intervention. Which methodology should the team adopt?

• A.Continuous Integration ensures code is merged frequently but does not deploy it to production.
• B.Continuous Delivery automates the release process but requires a manual approval step before production deployment.
• C.Continuous Deployment automates the entire pipeline, releasing changes to production automatically if all tests pass.✓ Correct
• D.Continuous Testing continuously runs automated tests against code but does not manage the deployment process.

2. A company is migrating from a traditional release cycle to a modern DevOps approach. They want developers to merge their code changes into a central repository multiple times a day, where automated builds and tests are run. Which practice are they implementing?

• A.Continuous Integration focuses on frequently merging developer changes into a main branch and running automated tests.✓ Correct
• B.Continuous Delivery focuses on ensuring the codebase is always in a deployable state for production releases.
• C.Continuous Deployment focuses on automatically deploying every change directly to end-users in production.
• D.Continuous Monitoring focuses on tracking application performance and system health after deployment.

3. A developer is trying to push code to an AWS CodeCommit repository using Git over HTTPS but receives an authentication error. The developer has an IAM user with the AWSCodeCommitPowerUser managed policy attached. What should the developer do to resolve this?

• A.Configure the AWS CLI credential helper for Git, which securely authenticates Git over HTTPS using IAM credentials.✓ Correct
• B.Create an SSH key pair, upload the public key to the IAM user, and change the Git remote URL to use SSH instead of HTTPS.
• C.Generate Amazon S3 access keys in IAM and use them as the username and password for the Git HTTPS connection.
• D.Attach the AWSCodeCommitFullAccess policy to the IAM user, as the PowerUser policy does not allow pushing code.

4. A team needs to securely store their application source code on AWS. They require encryption at rest using AWS KMS and the ability to integrate easily with AWS CodePipeline. Which AWS service is the most appropriate choice?

• A.Amazon S3 configured with versioning and server-side encryption to store source code archives.
• B.AWS CodeCommit, which is a fully managed source control service that hosts secure Git-based repositories.✓ Correct
• C.AWS CodeArtifact, which securely stores, publishes, and shares software packages and code dependencies.
• D.AWS CodeBuild, which securely stores source code and compiles it into deployable software packages.

5. A developer is configuring an AWS CodeBuild project and needs to define the commands to compile the code and the location of the compiled application. Which file must the developer create in the root of the source code repository?

• A.An appspec.yml file that defines the deployment actions, file locations, and lifecycle hooks for CodeDeploy.
• B.A buildspec.yml file that defines the build phases, commands to run, and the artifacts to output from the build process.✓ Correct
• C.A Dockerfile that defines the underlying operating system and dependencies needed to compile the application code.
• D.A pipeline.yaml file that orchestrates the flow of source code from the repository to the build environment.
