Answer: Utilize Amazon DynamoDB global tables for multi-Region replication
The correct answer is C, which suggests using Amazon DynamoDB global tables. This is because DynamoDB global tables provide a fully managed, multi-Region, and multi-active database replication solution. It automatically replicates data across multiple AWS Regions, ensuring low-latency read and write performance for global applications. This approach minimizes operational overhead by handling replication and data consistency across Regions without the need for manual intervention. The other options, such as using Amazon EC2 (A), Amazon RDS cross-Region replication (B), or AWS Database Migration Service (D), would require more operational management and do not inherently provide the same level of global data accessibility and replication as DynamoDB global tables.
