The answer is the CodeBuild test reports feature. This is correct because test reports allow developers to generate and publish code coverage reports directly to the CodeBuild console by specifying the report group and format in the buildspec.yml file, supporting formats like JaCoCo and Cobertura for Java applications. On the AWS Certified Developer Associate DVA-C02 exam, this question tests your understanding of how to centralize test analytics without external tools—a common trap is confusing test reports with CloudWatch metrics or S3 artifact storage, but the key distinction is that test reports are purpose-built for visualizing pass/fail rates and coverage percentages in the console. Remember the memory tip: "Reports for results, metrics for monitoring"—if the goal is to see code coverage in the CodeBuild console, always choose test reports.
DVA-C02 Deployment Practice Question
This DVA-C02 practice question tests your understanding of deployment. 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 is using AWS CodeBuild to build a Java application. The buildspec.yml file currently runs unit tests. The developer wants to generate a code coverage report and publish it to the CodeBuild console for analysis. Which CodeBuild feature should be used?
CodeBuild test reports enable you to generate and view code coverage and test result reports directly in the CodeBuild console, integrating with tools like JaCoCo.
B
Build artifacts
Why wrong: Build artifacts are output files (e.g., JARs, WARs) stored in S3, not reports for analysis in the console.
C
Amazon CloudWatch Logs
Why wrong: CloudWatch Logs capture build output log streams, but do not parse or display structured code coverage reports.
D
Amazon S3 access logs
Why wrong: S3 access logs record requests made to S3 buckets, unrelated to CodeBuild report generation.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Test reports
AWS CodeBuild's test reports feature allows developers to create reports from test result files, including code coverage reports, and publish them to the CodeBuild console for analysis. This feature supports various report formats such as JaCoCo, Cobertura, and SimpleCov, enabling the developer to visualize coverage metrics directly in the console without external tools.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Amazon CloudWatch Logs
Why it's wrong here

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse build artifacts (which store compiled binaries) with test reports (which store structured test and coverage data), or assume CloudWatch Logs can visualize coverage metrics when it only provides raw log text.
Trap categories for this question
Command / output trap
Build artifacts are output files (e.g., JARs, WARs) stored in S3, not reports for analysis in the console.
Detailed technical explanation
How to think about this question
CodeBuild test reports parse standard coverage report formats (e.g., JaCoCo's XML output) and store them in the CodeBuild service, where they are aggregated and displayed in the console with pass/fail thresholds and trend analysis. Under the hood, CodeBuild uses a built-in report group to associate reports with a project, allowing developers to set a coverage threshold that fails the build if not met—a critical feature for CI/CD pipelines enforcing quality gates.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
