Q1137. A company is developing a new online gaming application. The application will run on Amazon EC2 instances in multiple AWS Regions and will have a high number of globally distributed users. A solutions architect must design the application to optimize network latency for the users.Which actions should the solutions architect take to meet these requirements?(Select TWO.)
- A. Configure AWS Global Accelerator. Create Regional endpoint groups in each Region where an EC2 fleet is hosted. ✓
- B. Create a content delivery network (CDN) by using Amazon CloudFront. Enable caching for static and dynamic content, and specify a high expiration period. ✓
- C. Integrate AWS Client VPN into the application. Instruct users to select which Region is closest to them after they launch the application. Establish a VPN connection to that Region.
- D. Create an Amazon Route 53 weighted routing policy. Configure the routing policy to give the highest weight to the EC2 instances in the Region that has the largest number of users.
- E. Configure an Amazon API Gateway endpoint in each Region where an EC2 fleet is hosted. Instruct users to select which Region is closest to them after they launch the application. Use the API Gateway endpoint that is closest to them.
Correct Answer: A. Configure AWS Global Accelerator. Create Regional endpoint groups in each Region where an EC2 fleet is hosted., B. Create a content delivery network (CDN) by using Amazon CloudFront. Enable caching for static and dynamic content, and specify a high expiration period.
Explanation
To optimize network latency for globally distributed users of the online gaming application, the solutions architect should take the following actions:A. Configure AWS Global Accelerator. Create Regional endpoint groups in each Region where an EC2 fleet is hosted.B. Create a content delivery network (CDN) by using Amazon CloudFront. Enable caching for static and dynamic content, and specify a high expiration period.Explanation:A. AWS Global Accelerator: This service improves the availability and performance of your applications with users distributed globally. It directs user traffic to the optimal endpoint based on health, geography, and routing policies, reducing latency significantly for users connecting to EC2 instances.B. Amazon CloudFront: Implementing a CDN like CloudFront allows for caching both static and dynamic content closer to the users, which reduces latency when accessing game assets and other resources. This is crucial for enhancing the overall user experience in an online gaming application.Why Other Options Are Not Suitable:C. AWS Client VPN: While this could provide secure access, it is not an ideal solution for optimizing latency for gaming users as it requires users to manually select a region and establish a VPN connection, which adds complexity and may increase latency.D. Amazon Route 53 weighted routing policy: Although this could help in directing users to the nearest region, it does not provide the same level of performance optimization as Global Accelerator and may not account for real-time conditions affecting latency.E. Amazon API Gateway: While it could help route API calls to the closest region, instructing users to choose a region manually is not as seamless as using Global Accelerator or CloudFront for automatic optimization.By implementing options A and B, the application will be better optimized for low latency and high performance for users around the globe.
