DOP-C02 Exam Dumps : AWS Certified DevOps Engineer - Professional

The company’s primary goals are to produce daily builds, publish artifacts to an Amazon S3–hosted website, and do so with the least operational overhead. Because the source repository is public and builds are produced on a fixed daily schedule, there is no requirement for complex multi-stage orchestration or manual pipeline invocations.

Option B provides the most streamlined and AWS-recommended solution. By using AWS CodeBuild directly with the public repository as the source, the company eliminates the need to manage an AWS CodePipeline altogether. CodeBuild can natively compile the project and publish build artifacts directly to an Amazon S3 bucket through its artifacts configuration. This minimizes service dependencies and operational complexity.

Using an Amazon EventBridge scheduled rule to trigger the CodeBuild project daily ensures builds occur automatically without manual intervention. Enabling artifact encryption is the AWS best practice, even for public artifacts, because encryption at rest does not prevent public read access when bucket policies allow it.

Option A relies on webhooks and push-based triggers, which do not meet the “build every day” requirement and introduce unnecessary coupling to repository activity. Options C and D retain CodePipeline, which adds extra configuration and maintenance overhead without providing additional value for this simple build-and-publish workflow.

Therefore, Option B meets all requirements with the least operational effort while following AWS-recommended CI/CD design principles.

The correct answer is B. Creating a new AWS CodeBuild project and configuring a test stage in the AWS CodePipeline pipeline that uses the new CodeBuild project is the best way to integrate the unit tests into the existing pipeline. Creating a CodeBuild report group and uploading the test reports to the new CodeBuild report group will produce reports about the unit tests for the company to view. Using JUNITXML as the output format for the unit tests is supported by CodeBuild and will generate a valid report.

Option A is incorrect because Amazon CodeGuru Reviewer is a service that provides automated code reviews and recommendations for improving code quality and performance. It is not a tool for running unit tests or producing test reports. Therefore, option A will not meet the requirements.

Option C is incorrect because AWS CodeArtifact is a service that provides secure, scalable, and cost-effective artifact management for software development. It is not a tool for running unit tests or producing test reports. Moreover, option C uses CUCUMBERJSON as the output format for the unit tests, which is not supported by CodeBuild and will not generate a valid report.

Option D is incorrect because uploading the test reports to an Amazon S3 bucket is not the best way to produce reports about the unit tests for the company to view. CodeBuild has a built-in feature to create and manage test reports, which is more convenient and efficient than using S3. Furthermore, option D uses HTML as the output format for the unit tests, which is not supported by CodeBuild and will not generate a valid report.

When you create a pipeline from CodePipeline during the step-by-step it creates a CloudWatch Event rule for a given branch and repo

like this:

"aws.codecommit"

],

],

"detail": {
