Which design would you choose to meet these requirements?

An International company has deployed a multi-tier web application that relies on DynamoDB in a single region
For regulatory reasons they need disaster recovery capability In a separate region with a Recovery Time
Objective of 2 hours and a Recovery Point Objective of 24 hours They should synchronize their data on a
regular basis and be able to provision me web application rapidly using CloudFormation.
The objective is to minimize changes to the existing web application, control the throughput of DynamoDB used
for the synchronization of data and synchronize only the modified elements.
Which design would you choose to meet these requirements?

A.
Use AWS data Pipeline to schedule a DynamoDB cross region copy once a day. create a Lastupdated’attribute in your DynamoDB table that would represent the timestamp of the last update and use it as a filter.

B.
Use EMR and write a custom script to retrieve data from DynamoDB in the current region using a SCAN
operation and push it to QynamoDB in the second region.

C.
Use AWS data Pipeline to schedule an export of the DynamoDB table to S3 in the current region once a day
then schedule another task immediately after it that will import data from S3 to DynamoDB in the other
region.

D.
Send also each Ante into an SQS queue in me second region; use an auto-scaiing group behind the SQS
queue to replay the write in the second region.
