Topic 1 Question 447
A company has a stateless web application that runs on AWS Lambda functions that are invoked by Amazon API Gateway. The company wants to deploy the application across multiple AWS Regions to provide Regional failover capabilities.
What should a solutions architect do to route traffic to multiple Regions?
Create Amazon Route 53 health checks for each Region. Use an active-active failover configuration.
Create an Amazon CloudFront distribution with an origin for each Region. Use CloudFront health checks to route traffic.
Create a transit gateway. Attach the transit gateway to the API Gateway endpoint in each Region. Configure the transit gateway to route requests.
Create an Application Load Balancer in the primary Region. Set the target group to point to the API Gateway endpoint hostnames in each Region.

It's A It's not B because Amazon CloudFront can distribute traffic to multiple origins, but it does not support automatic failover between regions based on health checks. CloudFront is primarily a content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency and high transfer speeds.

This approach leverages the capabilities of CloudFront's intelligent routing and health checks to automatically distribute traffic across multiple AWS Regions and provide failover capabilities in case of Regional disruptions or unavailability.
