A company has an application that is deployed on AWS Elastic Beanstalk. The application generates user-specific PDFs and stores the PDFs in an Amazon S3 bucket. The application then uses Amazon Simple Email Service (Amazon SES) to send the PDFs by email to subscribers. Users no longer access the PDFs 90 days after the PDFs are generated. The S3 bucket is not versioned and contains many obsolete PDFs. A developer must reduce the number of files in the S3 bucket by removing PDFs that are older than 90 days. Which solution will meet this requirement with the LEAST development effort?

A developer must analyze performance issues with production-distributed applications written as AWS Lambda functions. These distributed Lambda applications invoke other components that make up me applications. How should the developer identify and troubleshoot the root cause of the performance issues in production?

A.
Add logging statements to the Lambda functions. then use Amazon CloudWatch to view the logs.
Answers
A.
Add logging statements to the Lambda functions. then use Amazon CloudWatch to view the logs.
B.
Use AWS CloudTrail and then examine the logs.
Answers
B.
Use AWS CloudTrail and then examine the logs.
C.
Use AWS X-Ray. then examine the segments and errors.
Answers
C.
Use AWS X-Ray. then examine the segments and errors.
D.
Run Amazon inspector agents and then analyze performance.
Answers
D.
Run Amazon inspector agents and then analyze performance.
Suggested answer: C

Explanation:

This solution will meet the requirements by using AWS X-Ray to analyze and debug the performance issues with the distributed Lambda applications. AWS X-Ray is a service that collects data about requests that the applications serve, and provides tools to view, filter, and gain insights into that data. The developer can use AWS X-Ray to identify the root cause of the performance issues by examining the segments and errors that show the details of each request and the components that make up the applications. Option A is not optimal because it will use logging statements and Amazon CloudWatch, which may not provide enough information or visibility into the distributed applications. Option B is not optimal because it will use AWS CloudTrail, which is a service that records API calls and events for AWS services, not application performance data. Option D is not optimal because it will use Amazon Inspector, which is a service that helps improve the security and compliance of applications on Amazon EC2 instances, not Lambda functions.
