Which Amazon S3 feature or storage class uses the AWS backbone network and edge locations to reduce latencies from the end user to Amazon S3?

Explanations:

S3 Cross-Region Replication is a feature that replicates objects across different AWS regions for redundancy and disaster recovery, but it does not specifically use the AWS backbone network and edge locations to reduce latencies.

S3 Transfer Acceleration utilizes the AWS backbone network and edge locations to optimize the transfer of files to and from Amazon S3, reducing latency by routing uploads and downloads through the closest edge location.

S3 Event Notifications allow you to trigger actions based on events occurring in your S3 buckets (like object creation or deletion), but they do not involve latency reduction for end-user access to Amazon S3.

S3 Standard-Infrequent Access (S3 Standard-IA) is a storage class designed for data that is accessed less frequently, but it does not use the AWS backbone network or edge locations to reduce latencies.
