AWS Certified DevOps Engineer – Professional — Question 30

A company wants to migrate a legacy application to AWS and develop a deployment pipeline that uses AWS services only. A DevOps engineer is migrating all of the application code from a Git repository to AWS CodeCommit while preserving the history of the repository. The DevOps engineer has set all the permissions within CodeCommit, installed the Git client and the AWS CLI on a local computer, and is ready to migrate the repository.
Which actions will follow?

Answer options

• A. Create the CodeCommit repository using the AWS CLI. Clone the Git repository directly to CodeCommit using the AWS CLI. Validate that the files were migrated, and publish the CodeCommit repository.
• B. Create the CodeCommit repository using the AWS Management Console. Clone both the Git and CodeCommit repositories to the local computer. Copy the files from the Git repository to the CodeCommit repository on the local computer. Commit the CodeCommit repository. Validate that the files were migrated, and share the CodeCommit repository.
• C. Create the CodeCommit repository using the AWS Management Console. Use the console to clone the Git repository into the CodeCommit repository. Validate that the files were migrated, and publish the CodeCommit repository.
• D. Create the CodeCommit repository using the AWS Management Console or the AWS CLI. Clone the Git repository with a mirror argument to the local computer and push the repository to CodeCommit. Validate that the files were migrated, and share the CodeCommit repository.

Correct answer: D

Explanation

Option D is correct because it efficiently uses the mirror option to clone the entire Git repository, ensuring that all history is preserved during the migration to CodeCommit. The other options either do not preserve history or require unnecessary steps, making them less effective for this migration process.
