A company hosts an encrypted Amazon S3 bucket in the ap-southeast-2 Region.

Comprehensive and Detailed Explanation From Exact Extract of AWS CloudOps Documents:

For users in eu-west-2 transferring large files to/from an S3 bucket in ap-southeast-2 over the public internet, S3 Transfer Acceleration is designed to improve performance by leveraging the AWS global edge network. With Transfer Acceleration enabled, users access the bucket via the acceleration endpoint. Requests enter AWS at the nearest edge location and then traverse the AWS backbone network to the bucket’s Region, which typically reduces latency variability and can improve throughput for long-distance transfers.

Option A is incorrect because access points do not “replicate destinations” in the way described, and an access point in another Region does not move data closer by itself. Option B is incorrect because Route 53 DNS routing does not accelerate data transfers; it only resolves names and (in this case) also incorrectly references S3 website endpoints (not appropriate for general large file transfer APIs). Option C is not valid as written because a single S3 access point cannot be “associated with both buckets,” and maintaining two buckets introduces synchronization/consistency overhead; it’s not the least-friction acceleration approach for direct internet users.
