A. B. C. D.Answer - A, B and D.
The AWS Documentation mentions the following.
Amazon CloudFront employs a global network of edge locations and regional edge caches that cache copies of your content close to your viewers.
Amazon CloudFront ensures that end-user requests are served by the closest edge location.
Regional edge caches are CloudFront locations that are deployed globally, close to your viewers.
They're located between your origin server and the POPs-global edge locations that serve content directly to viewers.
As objects become less popular, individual POPs might remove those objects to make room for more popular content.

https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/HowCloudFrontWorks.htmlAn edge location is a physical location where AWS deploys and maintains a collection of caching servers. These servers are used to provide lower latency and higher throughput to end-users who are accessing your applications or content. Edge locations are used in conjunction with Amazon CloudFront, a content delivery network (CDN) service.
The features of an edge location are as follows:
A. Distribute content to users: One of the primary features of an edge location is the ability to distribute content to end-users. When an end-user requests content from your application, the request is routed to the nearest edge location, where the content is cached. This helps to reduce latency and improve performance for end-users.
B. Cache popular contents: Another feature of an edge location is the ability to cache popular content. When an end-user requests content that has been previously requested by other users, the content is already cached at the edge location. This reduces the load on your origin servers and improves performance for end-users.
C. Distribute load across multiple resources: Edge locations can also distribute load across multiple resources. When an end-user requests content, the request is automatically routed to the nearest available edge location. If one edge location is overloaded, the request is automatically routed to another available edge location.
D. Used in conjunction with the CloudFront service: Edge locations are used in conjunction with the Amazon CloudFront service. CloudFront is a global CDN service that distributes your content to edge locations around the world. When an end-user requests content, the request is automatically routed to the nearest edge location using CloudFront.
