You need to deploy an application in multiple AWS Regions and want user traffic routed to the Region with the lowest latency. If a Region becomes unhealthy, traffic should automatically fail over to another Region that has a healthy application instance. The solution must provide the fastest possible failover. Which option satisfies these requirements?

AWS Global Accelerator provides static IP addresses that act as a fixed entry point to your application endpoints in multiple AWS Regions. It uses the AWS global network to route user traffic to the optimal healthy endpoint based on latency, ensuring the fastest possible failover. When an endpoint becomes unhealthy, Global Accelerator automatically directs traffic to the next healthiest endpoint, offering rapid failover. The Route 53 options (latency, failover, geolocation policies) rely on DNS propagation for changes, which can introduce delays in failover. While health checks help identify unhealthy endpoints, DNS caching can prevent immediate redirection, making Global Accelerator a faster and more robust solution for this scenario.
