AWS Certified SysOps Administrator – Associate (legacy) — Question 4

A photo-sharing site delivers content worldwide from a library on Amazon S3 using Amazon CloudFront. Users are trying to access photos that either do not exist or they are not authorized to view.
What should be monitored to better understand the extent of this issue?

Answer options

• A. GetRequests S3 metric on Amazon CloudWatch
• B. 4XXErrorRate CloudFront metric on CloudWatch
• C. 5XXErrorRate CloudFront metric on CloudWatch
• D. PostRequests S3 metric on CloudWatch

Correct answer: A

Explanation

Monitoring the GetRequests S3 metric on Amazon CloudWatch is crucial because it tracks the number of requests made to retrieve objects from S3. If users are trying to access non-existent or unauthorized photos, those requests will not succeed, providing critical insight into the issue. The 4XXErrorRate metric would indicate client-side errors but does not specifically tie to the request retrievals from S3, while 5XXErrorRate pertains to server errors, which are not relevant in this case.
