Question 248

A company has deployed an application in a single AWS Region. The application backend uses Amazon DynamoDB tables and Amazon S3 buckets.

The company wants to deploy the application in a secondary Region. The company must ensure that the data in the DynamoDB tables and the S3 buckets persists across both Regions. The data must also immediately propagate across Regions.

Which solution will meet these requirements with the MOST operational efficiency?

    Correct Answer: A

    To achieve immediate propagation of data across regions with minimal operational overhead, two-way S3 bucket replication and converting the DynamoDB tables into global tables is the most efficient solution. Two-way S3 bucket replication ensures that any changes to the data in one region are immediately reflected in the other region. DynamoDB global tables automatically manage the replication of data across multiple regions, ensuring immediate consistency and durability without additional complexity.

Discussion
trungtdOption: A

B & D. S3 Batch Operations copy jobs are not immediate and are typically used for bulk copying of data. They do not provide the immediacy required for data propagation across regions. C. DynamoDB streams with AWS Lambda functions to replicate data introduces additional complexity and operational overhead.
