Question

A company has a web application that is hosted on Amazon EC2 instances. The company is deploying the application into multiple AWS Regions. The application consists of dynamic content such as WebSocket-based real-time product updates. The company uses Amazon Route 53 to manage all DNS records. Which solution will provide multi-Region access to the application with the LEAST latency?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Deploy a Network Load Balancer (NLB) in front of the EC2 instances in each Region. Deploy an AWS Global Accelerator standard accelerator with an endpoint group for each NLB. Create a Route 53 alias record that points... Amazon EC2 provides resizable virtual servers when you need full control of the operating system. AWS Global Accelerator routes users over the AWS backbone to the optimal endpoint for lower latency and fast failover. Amazon Route 53 provides DNS with health checks and routing policies for availability and latency. This option meets the real-time / low-latency performance requirement.
