A report-download site must deliver PDFs quickly to citizens worldwide from objects stored in Amazon S3. Which service should sit in front for global edge caching?
Select an answer to reveal the explanation.
Short Explanation
World-wide PDF grabs want a CDN porch light—CloudFront caches from S3 at the edge. DataSync, MQ, and Direct Connect solve other problems; they are not citizen download CDNs.
Full Explanation
Amazon CloudFront is the CDN that caches static content such as PDFs from an S3 origin at edge locations for global performance. DataSync moves data, Amazon MQ is messaging, and Direct Connect is private network connectivity—not a public edge cache for downloads.
