AWS DevOps Engineer Professional DOP-C01 – Question170

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.
