AWS Certified Solutions Architect – Associate (SAA-C03) — Question 334

A company is designing the network for an online multi-player game. The game uses the UDP networking protocol and will be deployed in eight AWS Regions. The network architecture needs to minimize latency and packet loss to give end users a high-quality gaming experience.

Which solution will meet these requirements?

Answer options

• A. Setup a transit gateway in each Region. Create inter-Region peering attachments between each transit gateway.
• B. Set up AWS Global Accelerator with UDP listeners and endpoint groups in each Region.
• C. Set up Amazon CloudFront with UDP turned on. Configure an origin in each Region.
• D. Set up a VPC peering mesh between each Region. Turn on UDP for each VPC.

Correct answer: B

Explanation

AWS Global Accelerator is designed to optimize latency and minimize packet loss by routing user traffic over the congestion-free AWS global network, and it natively supports UDP listeners. Amazon CloudFront does not support UDP traffic routing to custom origins, making option C incorrect. Options A and D facilitate internal inter-VPC and inter-Region communication rather than optimizing the internet ingress path for external game clients.
