QuickDialog is a multimedia company running a messaging app. One of the principal features of QuickDialog is that pictures and messages are usually only available for a short time before they become inaccessible to users. The app has evolved from originally centering on person-to-person photo sharing to present users` "Stories" of 24 hours of sequential content, along with "Discover", allowing brands show ad-supported short-form media.
They use DynamoDB to support the mobile application and S3 to host the images and other documents shared between users. KindleYou has a large customer base spread across multiple geographic areas. Customers need to update their profile information while using the application. Propose a solution that can be easily implemented and provides full consistency.
Select 1 Option

Answer options:

A.Use global tables, a fully managed solution across multiple regions, multi-master databases
B.Create CustomerProfile table in a region, create replication copies in different AWS regions and enable replication through AWS Kinesis Data Streams
C.Create CustomerProfile table in a region, create replication copies in different AWS regions and enable replication through AWS Data Pipeline
D.Create CustomerProfile table in a region, create replication copies in different AWS regions and enable replication through AWS Kinesis Data Firehose

Answer: A
Option A is correct -Amazon DynamoDB global tables provide a fully managed solution for deploying a multi- region, multi-master database, without having to build and maintain your own replication solution. Replication is performed by DynamoDB streams

Option B is incorrect -Replication with Kinesis Streams is possible, but does not provide full consistency. But again producers using KPL and Consumers need to be configured
https://docs.aws.amazon.com/streams/latest/dev/key-concepts.html
Option C is incorrect -Replication with Data Pipeline is based on pipelines and schedule. It cannot be real-time and does not provide full consistency
https://docs.aws.amazon.com/datapipeline/latest/DeveloperGuide/what-is-datapipeline.html
Option D is incorrect -Replication with Kinesis Firehose runs with a lag. It cannot be real-time and does not provide full consistency
