DOP-C02 SDLC Automation Practice Question
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 developer wants to automate the testing of a serverless application built with AWS Lambda and Amazon API Gateway. Which AWS service is best suited for running integration tests as part of a CI/CD pipeline?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS CodeBuild
AWS CodeBuild is best suited for running integration tests as part of a CI/CD pipeline because it is a fully managed continuous integration service that can compile source code, run tests, and produce software packages. For a serverless application using Lambda and API Gateway, CodeBuild can execute integration tests against deployed API endpoints, validate Lambda function responses, and integrate seamlessly with other AWS developer tools like CodePipeline. It supports custom build environments and can run test frameworks (e.g., Postman/Newman, Jest) directly in the pipeline.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS CodeBuild with AWS CodeDeploy, assuming that deployment services inherently include testing capabilities, but CodeDeploy only handles the deployment process and does not execute test scripts or validate application behavior.
Detailed technical explanation
How to think about this question
Under the hood, CodeBuild uses a Docker container-based build environment where you can define a buildspec.yml file that includes phases like 'install', 'pre_build', 'build', and 'post_build'. For integration testing, you can run tools like Newman (Postman CLI) to execute API Gateway endpoint tests, or use AWS SDK calls to invoke Lambda functions directly and assert responses. A real-world scenario is when a pipeline deploys a new version of a Lambda function via CloudFormation, then CodeBuild runs a suite of integration tests against the API Gateway stage to ensure the new version doesn't break existing functionality before promoting the change to production.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
