Which AWS service routes user traffic at the IP layer with anycast addressing and Region failover, often used in front of TCP/UDP workloads needing single-digit-ms global failover?
AAmazon Route 53 alias records only
BAmazon CloudFront caching
CAWS Global Accelerator
DAmazon API Gateway
Answer & Solution
Correct answer: C. AWS Global Accelerator
Global Accelerator publishes anycast IPs that route to the nearest healthy endpoint over AWS's global network. Route 53 alone does DNS (slower failover); CloudFront accelerates HTTP via caches; API Gateway is an API-tier service.
