Which AWS service caches content at edge locations worldwide to deliver it to users with lower latency?
A.Amazon Route 53
Route 53 is DNS routing, not content caching.
B.Amazon CloudFront
Correct. CloudFront is the CDN service.
C.AWS Global Accelerator
Global Accelerator improves network routing but doesn't cache content.
D.Elastic Load Balancing
ELB distributes traffic to backends — not edge caching.
Why this answer
CloudFront is AWS's CDN — it caches content at hundreds of edge locations so users download from a nearby PoP instead of the origin. Route 53 is DNS; Global Accelerator routes traffic (doesn't cache).
