B should be correct. With CloudWatch request metrics for Amazon S3, you can receive 1-minute CloudWatch metrics, set CloudWatch alarms, and access CloudWatch dashboards to view near-real-time operations and performance of your Amazon S3 storage.

Selected Answer: B
The 4XXErrorRate CloudFront metric specifically tracks the rate of HTTP 4xx client error responses generated by CloudFront. This metric includes errors such as 404 (Not Found) or 403 (Forbidden), which are relevant to the scenario where users are trying to access photos that do not exist or they are not authorized to view.

Answer should be B. A cannot be correct. Getrequest metric is a count and not an HTTP request code,
