Suggested answer: C

Explanation:

Amazon DynamoDB global tables are a fully managed, serverless, multi-Region, and multi-active database option that delivers fast and localized read and write performance for massively scaled global applications.Global tables provide you 99.999% availability, increased application resiliency, and improved business continuity1.As global tables replicate your Amazon DynamoDB tables automatically across your choice of AWS Regions, you can achieve fast, local read and write performance1.In the rare event of a single Region failure, there is no need for a database failover as global tables' multi-active architecture allows customers to read and write to any replica table1.Global tables also eliminate the difficult work of replicating data between Regions and resolving update conflicts for multi-active workloads1.

Using Amazon DynamoDB global tables, the company can:

Set up an active-active configuration and near real-time synchronization of data across tables in multiple AWS Regions.

Meet the RTO and RPO of less than 5 minutes, as global tables provide automatic failover and zero data loss in case of a Region failure.

Achieve high availability, durability, and scalability for their application.
