SAA-C03 Q405 · Database

Question

A gaming company is building an application that uses a database to store user data. The company wants the database to have an active-active configuration that allows data writes to a secondary AWS Region. The database must achieve a sub-second recovery point objective (RPO). Which solution will meet these requirements?

Accepted Answer

**Answer D: DynamoDB Global Tables** meets every requirement:

1. **Active-Active Configuration**: DynamoDB Global Tables is a fully managed, multi-Region, multi-active database. Every replica table in every Region can accept both **read and write** operations. This is true active-active — not active-passive.

2. **Data Writes to a Secondary Region**: Because each Region's table accepts writes independently, applications in the secondary Region can write directly to their local replica. Changes are automatically replicated to all other Regions.

3. **Sub-second RPO**: DynamoDB Global Tables typically replicate data across Regions with a **replication latency under one second** (usually measured in hundreds of milliseconds). This ensures that even if an entire Region fails, less than one se
