How does Amazon CloudFront use Edge Locations to improve content delivery?a)By replicating data across multiple data centersb)By encrypting data during transmissionc)By compressing data before it is delivered to end-usersd)By caching frequently accessed content at Edge Locations
Solution
Amazon CloudFront improves content delivery using Edge Locations primarily through the method of caching frequently accessed content. Here's a step-by-step explanation:
-
When a user requests content (like a video, image, or document), the request is routed to the nearest edge location, which helps deliver the content more quickly than if it had to be accessed from the original server.
-
The first time the content is requested, CloudFront retrieves it from the origin server (like an Amazon S3 bucket or a web server) and then caches (stores) it in the edge location.
-
When another user requests the same content, CloudFront can deliver it directly from the edge location. This means the content is closer to the user, reducing latency and improving speed.
-
CloudFront also maintains persistent connections with the origin servers so that it can fetch content quickly when it's not already cached.
So, the correct answer to your question is d) By caching frequently accessed content at Edge Locations.
