Users worldwide download static media from a single-Region S3 bucket and experience high latency. What reduces latency with minimal architecture change?
A.Enable S3 Transfer Acceleration for downloads
Transfer Acceleration primarily speeds long-distance uploads/downloads to a specific bucket endpoint; edge caching serves repeated reads faster and cheaper.
B.Put a CloudFront distribution in front of the bucket to cache content at edge locations
Correct. CloudFront edge caching is the canonical answer for global static-content latency.
C.Move the bucket to a Region closer to the largest user group
Moving the bucket only moves the problem to distant users.
D.Enable S3 versioning
Versioning protects data; it does not improve latency.
Why this answer
CloudFront caches objects at globally distributed edge locations so users download from a nearby PoP — the standard CDN pattern for static content with minimal change to the origin.
