An application needs to serve static images to users in 50 countries with the lowest possible latency, without re-architecting the origin. Which AWS service most directly solves this?
AAmazon S3 Glacier Deep Archive, by storing the images for retrieval within 12 hours
BAWS Direct Connect, by giving every user a dedicated fiber line into AWS
CAmazon EBS, by attaching the volume to every EC2 instance globally
DAmazon CloudFront, which caches the assets at AWS Edge Locations close to end users
Answer & Solution
Correct answer: D. Amazon CloudFront, which caches the assets at AWS Edge Locations close to end users
CloudFront is AWS's CDN — it pulls origin content (e.g., from an S3 bucket) into edge caches at hundreds of POPs worldwide so users see the file from a nearby location. EBS is single-AZ block storage; Glacier Deep Archive is for archival; Direct Connect is per-customer fiber, not user-facing.
