ANS-C01 Network Design Practice Question
A company is designing a network for a real-time gaming application that requires low latency and high throughput between game servers in multiple regions. The application uses UDP traffic. Which AWS service should be used to route traffic between regions?
⚠ Common exam trap
Candidates often confuse Amazon Route 53's latency-based routing with actual network path optimization, but Route 53 only controls DNS resolution and does not accelerate or route the UDP traffic itself after the initial connection.

Correct answer & explanation
✓
AWS Global Accelerator
AWS Global Accelerator uses the Anycast IP address and the AWS global network to route UDP traffic from users to the optimal regional endpoint, minimizing latency and jitter. It is designed for real-time applications like gaming that require low-latency and high-throughput UDP traffic between regions, as it bypasses the public internet and leverages AWS's internal backbone.
