Topic #: 1

[All AWS Certified Database - Specialty Questions]

A company wants to implement a design that includes multiple AWS Regions to support disaster recovery for its application. The company currently has a static website that is hosted on Amazon S3 and Amazon CloudFront. The application connects to an existing Amazon DynamoDB database in the us-east-1 Region. The DynamoDB table was recently created and was initialized with a large amount of company data. The company wants to replicate the database in real time to the us-west-2 Region.

A database specialist needs to perform the replication, which must include all existing table data and any new data that is added in the future, in an automated way.

Which solution will meet these requirements?

A. Enable DynamoDB streams. Configure streams for new and old images. Create a global table replica in us-west-2. Monitor the progress of the replication until the status changes to Active.
B. Create global table replica in us-west-2. Monitor the progress of the replication until the status changes to Active.
C. Enable DynamoDB streams. Configure streams for new and old images. Create a global table replica in us-west-2. Copy all existing data from us-east-1 to us-west-2 by using an export and batch import.
D. Create a global table replica in us-west-2. Copy all existing data from us-east-1 to us-west-2 by using an export and batch import.

I changed the answer to A. We must enable streams for the DynamoDB global table. https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/globaltables_reqs_bestpractices.html

Selected Answer: A

By enabling DynamoDB Streams and configuring both new and old images in the stream, you ensure that all changes to the DynamoDB table are captured. Creating a global table replica in the us-west-2 region allows for real-time replication of the table data. By monitoring the progress of replication and ensuring the status is active, you can verify the successful replication of the data. This solution ensures that all existing table data and future additions are included in an automated manner, replicating the data from the us-east-1 region to the us-west-2 region. Therefore, the solution that meets these requirements is option A.
