AWS Certified Developer Associate DVA-C02 Practice Question

The correct service is AWS X-Ray, which is designed to analyze and debug distributed applications like serverless functions. It provides end-to-end tracing, which creates a service map to visualize a request's entire execution path and helps identify performance bottlenecks. Amazon Inspector is a security assessment service that scans for vulnerabilities and is not used for performance analysis. Amazon CodeGuru Profiler analyzes application runtime performance to find the most expensive lines of code, but it does not provide the end-to-end distributed tracing that X-Ray does. AWS CloudTrail is an auditing service that records API calls made to an AWS account for governance and compliance, not for debugging application code performance.
