AWS Certified Developer – Associate (DVA-C02) — Question 492

A large company has its application components distributed across multiple AWS accounts. The company needs to collect and visualize trace data across these accounts.

What should be used to meet these requirements?

Answer options

• A. AWS X-Ray
• B. Amazon CloudWatch
• C. Amazon VPC flow logs
• D. Amazon OpenSearch Service

Correct answer: A

Explanation

AWS X-Ray is designed specifically to collect and visualize trace data, supporting cross-account tracing to track requests as they travel across multiple AWS accounts. Amazon CloudWatch primarily focuses on metrics and logs rather than distributed tracing visualization, while VPC flow logs only capture network traffic. Amazon OpenSearch Service is an ingestion and search engine but does not natively provide the specialized out-of-the-box cross-account tracing capabilities of AWS X-Ray.
