Which content delivery service can improve latency for globally distributed data and content?

• A. AWS Direct Connect
• B. Amazon S3
• C. Amazon CloudFront
• D. AWS Glue

Answer: (C)

Delivering content with low latency globally relies on an edge network that caches popular items close to users. Amazon CloudFront acts as a content delivery network, placing cache servers worldwide so requests are served from the nearest edge location rather than traveling back to a central origin. This edge caching dramatically reduces round-trip time and speeds up delivery for globally distributed data and assets. CloudFront can use origins like Amazon S3 or EC2, handling caching, invalidation, and security to ensure efficient, fast delivery. The other options aren’t designed to provide global content delivery via edge caching: AWS Direct Connect is about creating a private, dedicated network path into AWS, not caching content near end users; Amazon S3 is durable storage, not a CDN that reduces latency through edge delivery (though it can serve as an origin); AWS Glue is an ETL service for data processing, not for content delivery.
