A retail company is about to migrate its online and mobile store to AWS. The company’s CEO has strategic plans to grow the brand globally. A Database Specialist has been challenged to provide predictable read and write database performance with minimal operational overhead.
What should the Database Specialist do to meet these requirements?
- A . Use Amazon DynamoDB global tables to synchronize transactions
- B . Use Amazon EMR to copy the orders table data across Regions
- C . Use Amazon Aurora Global Database to synchronize all transactions
- D . Use Amazon DynamoDB Streams to replicate all DynamoDB transactions and sync them
Suggested Answer: A
Explanation:

With global tables, your globally distributed applications can access data locally in the selected regions to get single-digit millisecond read and write performance.
Not Aurora Global Database, as per this link: https://aws.amazon.com/rds/aurora/global-database/?nc1=h_ls. Aurora Global Database lets you easily scale database reads across the world and place your applications close to your users.
