The correct option is A CloudFront CDN point of presence that caches content near viewers. An edge location is a CloudFront point of presence that caches and delivers content closer to end users to reduce latency.

Edge locations function as cache points in CloudFront's global network and they serve static and dynamic content from the POP nearest the viewer so requests have lower latency and place less load on the origin. When you see the term edge location you should associate it with CloudFront POPs and caching rather than general network connectivity.

An AWS Direct Connect location is incorrect because it provides dedicated private network connections between your on prem network and AWS and it is not a CloudFront POP or a caching service.

A public Amazon S3 endpoint is incorrect because it provides access to S3 objects and does not act as a CDN cache that places content near viewers.

A virtual private gateway for a Site-to-Site VPN is incorrect because it is a VPN termination component used for VPC connectivity and it is unrelated to content delivery or caching.
