Quick Answer
The answer is AWS CodeBuild, the fully managed continuous integration service that compiles source code, runs tests, and produces software packages ready for deployment. For a CI/CD pipeline build service, AWS CodeBuild is the correct choice because it handles the build and test phase without requiring you to provision or manage servers—it scales automatically and integrates natively with Amazon ECS for containerized deployments. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your ability to distinguish between the core CI/CD services: CodeCommit for source control, CodeBuild for building and testing, CodeDeploy for deployment, and CodePipeline for orchestration. A common trap is confusing CodeBuild with CodePipeline, but remember that CodePipeline is the pipeline orchestrator that triggers CodeBuild as a build action. For a quick memory tip: think “Build” in CodeBuild equals the “compile and test” stage, while “Pipeline” is the overall workflow manager.
This SAP-C02 practice question tests your understanding of design for new solutions. 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 company is designing a new CI/CD pipeline for a web application that will be deployed on Amazon ECS. Which AWS service should the company use to build and test the application code?
AWS CodePipeline
Why wrong: CodePipeline orchestrates the CI/CD pipeline but does not build code.
AWS CodeDeploy
Why wrong: CodeDeploy is for deploying code to compute services.
AWS CodeCommit
Why wrong: CodeCommit is for storing code, not building.
AWS CodeBuild
CodeBuild is a managed build service for compiling 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 CodeBuild
Option B is correct because AWS CodeBuild is a fully managed build service. Option A is wrong because CodeCommit is a source control service. Option C is wrong because CodeDeploy is a deployment service. Option D is wrong because CodePipeline is a continuous delivery 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.
AWS CodePipeline
Why it's wrong here
CodePipeline orchestrates the CI/CD pipeline but does not build code.
AWS CodeDeploy
Why it's wrong here
CodeDeploy is for deploying code to compute services.
AWS CodeCommit
Why it's wrong here
CodeCommit is for storing code, not building.
AWS CodeBuild
Why this is correct
CodeBuild is a managed build service for compiling and testing code.

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.
