AWS Certified Developer Associate Practice Test 1

Correct answer - "X-Ray" : AWS X-Ray helps developers analyze and debug production, distributed applications, such as those built using a microservices architecture. With X-Ray, you can understand how your application and its underlying services are performing to identify and troubleshoot the root cause of performance issues and errors. X-Ray provides an end-to-end view of requests as they travel through your application, and shows a map of your application's underlying components.

Incorrect:

"CloudTrail" - The calls captured include calls from the AWS Lambda console and code calls to the AWS Lambda API operations. X-Ray uses trace data from the AWS resources that power your cloud applications to generate a detailed service graph making it a better tool

"CloudWatch Logs" - AWS Lambda leverages Amazon CloudWatch to automatically emit metrics and logs for all invocations of your function

"Systems Manager" - This service helps manage servers, maintain security and compliance by scanning your instances against your patch, configuration, and custom policies
