Question
A company has an application that uses an Amazon API Gateway REST API, AWS Lambda functions, and an Amazon DynamoDB table. The application currently runs in a single AWS Region. The company wants to make the application highly available across two Regions. User traffic must be routed to the Region that provides the least latency. Which combination of steps will meet these requirements? (Choose three.)
Options
- ACreate a replica of the DynamoDB table in a second Region.
- BCreate a global secondary index for the DynamoDB table.
- CCreate copies of the REST API and the Lambda functions in a second Region.
- DCreate health checks in Amazon Route 53. Create DNS records that include a failover routing
- ECreate health checks in Amazon Route 53. Create DNS records that include a latency routing
- FCreate DNS records in Amazon Route 53 that include a multivalue answer routing policy.

Explanation
Replicating the DynamoDB table in a second Region ensures data availability and consistency. Deploying copies of the REST API and Lambda functions in a second Region provides redundancy and local compute resources. Configuring Route 53 with latency-based routing ensures that user traffic is directed to the Region with the lowest latency, meeting the requirements for high availability and performance.
