Quick Answer
The answer is AWS CloudFormation, as it is the correct service to automate the creation of a CodeCommit repository using infrastructure as code. CloudFormation treats CodeCommit repositories as first-class AWS resources, allowing you to define them declaratively in a template alongside other infrastructure components like IAM roles or S3 buckets, which ensures repeatable, version-controlled provisioning. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this question tests your ability to distinguish between services that *manage* resources versus those that *orchestrate* or *build* them—a common trap is confusing CodePipeline (which automates CI/CD workflows) with CloudFormation’s resource management role. Remember that CodeCommit, CodeBuild, and CodePipeline are all part of the CI/CD pipeline, but only CloudFormation handles the infrastructure definition itself. Memory tip: “Formation creates the foundation; Pipeline moves the product.”
This DOP-C02 practice question tests your understanding of sdlc automation. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A DevOps engineer needs to automate the creation of a new AWS CodeCommit repository when a new project starts. The engineer wants to use infrastructure as code. Which service should be used?
AWS CloudFormation
CloudFormation can define CodeCommit repositories as resources.
AWS CodePipeline
Why wrong: CodePipeline is for CI/CD pipelines, not creating resources.
AWS CodeStar
Why wrong: CodeStar is a project dashboard, not infrastructure as code.
AWS CodeBuild
Why wrong: CodeBuild is for building and testing code.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AWS CloudFormation
Option A is correct because AWS CloudFormation can manage CodeCommit repositories as resources. Option B is wrong because CodePipeline orchestrates CI/CD, not resource creation. Option C is wrong because CodeStar is a project management tool, not infrastructure as code. Option D is wrong because CodeBuild is a build service.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
