DVA-C02 Development with AWS Services Practice Question
A developer is using AWS CodeBuild to run unit tests as part of a CI/CD pipeline. The developer wants to store the test results for later analysis. Which TWO AWS services can the developer use to store and view the test reports?
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 test reports
AWS CodeBuild test reports is a built-in feature that allows you to view test results directly in the CodeBuild console, enabling analysis of test reports. Option D: Amazon S3 can be used to store raw test result files (e.g., XML reports) for later retrieval and analysis. Option B: AWS X-Ray is for distributed tracing, not for storing test reports. Option C: Amazon Athena is a query service for data in S3, not a storage or viewing service for test reports. Option E: Amazon CloudWatch Logs is for log data, not structured test reports.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
AWS CodeBuild test reports
Why this is correct
AWS CodeBuild's native test reporting feature ingests test result files (such as JUnit XML or NUnit XML) declared in the buildspec's `reports` section, groups them into a test report group, and produces visual pass/fail metrics, trends, and failure summaries in the CodeBuild console. This is the intended, fully managed mechanism for analyzing unit test outcomes directly within the CI/CD pipeline without needing separate services.
- ✗
AWS X-Ray
Why it's wrong here
AWS X-Ray traces end-to-end requests through distributed applications, generating service graphs and trace segments to pinpoint latency and errors at runtime. It does not parse test result files, track unit test pass rates, or produce build-quality reports, so it is irrelevant to CodeBuild unit test reporting.
- ✗
Amazon Athena
Why it's wrong here
Amazon Athena is an interactive SQL query engine that runs directly on data stored in Amazon S3, often used for ad-hoc analytics over log files and structured datasets. While you could point Athena at test result files, you would first need to define tables and write queries, and it offers no built-in CodeBuild integration, test report groups, or trend dashboards.
- ✓
Amazon S3
Why this is correct
Amazon S3 is a valid companion because CodeBuild can upload the raw test result files (for example, JUnit-compatible XML) to an S3 bucket for durable retention, auditing, or downstream processing. It enables long-term storage and sharing of artifacts, but it does not by itself aggregate results into the structured, searchable reports that CodeBuild's test reporting feature provides.
- ✗
Amazon CloudWatch Logs
Why it's wrong here
Amazon CloudWatch Logs stores the raw log output generated by CodeBuild builds, including console output from running tests, and offers log-group insights with Logs Insights queries. It is not a structured test-reporting service: it treats output as free-form text lines rather than test case/status records, so it cannot natively produce pass/fail summaries or quality gates.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
