Question 16
Domain 2: Design Resilient ArchitecturesA company wants to implement a global accelerator for their application with static IP addresses and deterministic routing. Which service should be used?
Correct answer: B
Explanation
AWS Global Accelerator is the edge networking service for global applications that need static IPs and deterministic routing. The source material lists it under “Edge networking services with appropriate use cases” and “network routes to minimize network transfer costs,” which matches the requirement for stable IP addresses and predictable traffic flow.
Why each option is right or wrong
A. Amazon CloudFront
B. AWS Global Accelerator
AWS Global Accelerator is the edge networking service designed for global applications that need two static anycast IPv4 addresses and deterministic traffic flow over the AWS global network. It is the correct fit here because it provides fixed entry points for clients while routing traffic to the optimal healthy endpoint, rather than relying on changing regional IPs or DNS-only steering.
C. Route 53 with Latency Routing
D. Elastic Load Balancing
