Which AWS infrastructure component is designed to serve cached content closest to end users — lowering latency for a global audience?
A.An Availability Zone
AZs are isolated data centers within a Region for resilience, not content caching.
B.A CloudFront edge location / point of presence
Correct. Edge PoPs are CloudFront's global cache footprint.
C.A second Region
A second Region hosts infrastructure — users still fetch from it directly.
D.A local subnet
Subnets are VPC network segments, unrelated to content delivery.
Why this answer
CloudFront edge locations (points of presence) cache content near users worldwide. Regions/AZs host your infrastructure; edge locations accelerate delivery to end users.
