Question 63 of 65 | ← Chapter 5

Q363. A gaming company is building an application with Voice over IP capabilities. The application will serve traffic to users across the world. The application needs to be highly available with an automated failover across AWS Regions. The company wants to minimize the latency of users without relying on IP address caching on user devices.What should a solutions architect do to meet these requirements?

• A. Use AWS Global Accelerator with health checks ✓
• B. Use Amazon Route 53 with a geolocation routing policy
• C. Create an Amazon CloudFront distribution that includes multiple origins
• D. Create an Application Load Balancer that uses path-based routing

Correct Answer: A. Use AWS Global Accelerator with health checks

Explanation

Global Accelerator is a service that improves the availability and performance of applications by directing user traffic to the closest AWS edge location. It uses the AWS global network infrastructure to optimize the routing path and minimize latency. By configuring health checks, AWS Global Accelerator can automatically detect failures and route traffic to healthy endpoints in different AWS Regions, ensuring high availability.Option B, using Amazon Route 53 with aolocation routing policy, is not the best choice because it routes traffic based on the geographic location of the user, which may not necessarily result the lowest latency for all users.Option C, creating an Amazon CloudFront distribution with multiple origins, is also not the ideal choice as it primarily focuses on content delivery and caching rather than providing automated failover across AWS Regions.Option D, creating an Application Load Balancer with path-based routing, is suitable for distributing traffic within a single region but does not provide automated failover across AWS Regions.
