AWS Certified Solutions Architect – Professional — Question 691

A mobile gaming company is expanding into the global market. The company's game servers run in the us-east-1 Region. The game's client application uses UDP to communicate with the game servers and needs to be able to connect to a set of static IP addresses.
The company wants its game to be accessible on multiple continents. The company also wants the game to maintain its network performance and global availability.
Which solution meets these requirements?

Answer options

• A. Provision an Application Load Balancer (ALB) in front of the game servers. Create an Amazon CloudFront distribution that has no geographical restrictions. Set the ALB as the origin. Perform DNS lookups for the cloudfront.net domain name. Use the resulting IP addresses in the game's client application.
• B. Provision game servers in each AWS Region. Provision an Application Load Balancer in front of the game servers. Create an Amazon Route 53 latency-based routing policy for the game's client application to use with DNS lookups.
• C. Provision game servers in each AWS Region. Provision a Network Load Balancer (NLB) in front of the game servers. Create an accelerator in AWS Global Accelerator, and configure endpoint groups in each Region. Associate the NLBs with the corresponding Regional endpoint groups. Point the game client's application to the Global Accelerator endpoints.
• D. Provision game servers in each AWS Region. Provision a Network Load Balancer (NLB) in front of the game servers. Create an Amazon CloudFront distribution that has no geographical restrictions. Set the NLB as the origin. Perform DNS lookups for the cloudfront.net domain name. Use the resulting IP addresses in the game's client application.

Correct answer: C

Explanation

AWS Global Accelerator is the ideal solution because it provides static IP addresses and supports the UDP protocol, routing traffic over the high-performance AWS global network directly to Network Load Balancers (NLBs). Application Load Balancers (ALBs) and Amazon CloudFront do not support UDP traffic, which rules out options A, B, and D. Additionally, Route 53 latency-based routing does not provide the required static, anycast IP addresses that Global Accelerator offers.
