DBS-C01 Workload-Specific Database Design Practice Question
A company is designing a multi-region active-active application that requires low-latency reads and writes across regions. The database must support conflict resolution. Which database should be used?
⚠ Common exam trap
A common mix-up: candidates confuse Amazon Aurora Global Database with an active-active solution, but it is actually active-passive with a single write region, whereas DynamoDB Global Tables supports multi-region writes with automatic conflict resolution.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon DynamoDB Global Tables
Amazon DynamoDB Global Tables is the correct choice because it provides a fully managed, multi-region, multi-active database that replicates data across regions with eventual consistency, supporting low-latency reads and writes. It includes built-in conflict resolution using a last-writer-wins (LWW) mechanism based on timestamps, which meets the requirement for conflict resolution in an active-active architecture.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon RDS Multi-AZ
Why it's wrong here
RDS Multi-AZ is for high availability within a single region.
- ✓
Amazon DynamoDB Global Tables
Why this is correct
DynamoDB global tables offer active-active replication with eventual consistency and conflict resolution.
- ✗
Amazon Redshift
Why it's wrong here
Redshift is not designed for multi-region active-active workloads.
- ✗
Amazon Aurora Global Database
Why it's wrong here
Aurora Global Database supports only one primary region for writes, not active-active.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is designing a database for a global application that requires active-active replication across two AWS Regions. The database must support multi-master writes with conflict resolution. Which AWS database service should they use?
medium- A.Amazon Aurora Global Database
- ✓ B.Amazon DynamoDB Global Tables
- C.Amazon Redshift
- D.Amazon RDS for MySQL with Multi-AZ
Why B: Amazon DynamoDB Global Tables provides fully managed, multi-Region, multi-master replication, enabling active-active writes across two AWS Regions with built-in conflict resolution using last-writer-wins (based on timestamp). This directly meets the requirement for multi-master writes and conflict resolution without custom code.
