A company has a web application that uses an Amazon DynamoDB table in a single AWS Region to store user information. To support an increasingly global user base, the application must run in a secondary Region and allow users to connect to their closest Region and fail over to the secondary Region.
Which approach should be used to ensure the deployment meets these requirements?
A . Configure DynamoDB streams to copy data between Regions, deploy the web stack in both Regions, and configure Amazon Route 53 to use a geoproximity routing policy with health checks.
B . Convert the DynamoDB table to a global table, deploy the web stack in both Regions, and configure Amazon Route 53 to use a geoproximity routing policy with health checks.
C . Define DynamoDB cross-region backups to copy data to the secondary Region, deploy the web stack in both Regions, and configure Amazon Route 53 to use a latency-based routing policy with health checks.
D . Use DynamoDB Accelerator to copy data to the secondary Region, deploy the web stack in both Regions, and configure Amazon Route 53 to use a failover routing policy.
