DBS-C01 Workload-Specific Database Design Practice Question
Which THREE considerations are important when designing a database for a global, multi-Region application using Amazon DynamoDB Global Tables? (Select THREE.)
⚠ Common exam trap
The DBS-C01 exam often tests the misconception that Global Tables require a single write region or support cross-region strongly consistent reads, when in fact they are designed for multi-region writes with eventual consistency and automatic conflict resolution via last writer wins.
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
✓
Application tolerance for eventually consistent reads
Amazon DynamoDB Global Tables use an eventually consistent model for cross-region replication. Applications must tolerate eventual consistency, as updates made in one region are propagated to other regions asynchronously, typically within one second or less. This design trade-off enables high availability and low-latency writes across multiple regions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Using a single write region to avoid conflicts
Why it's wrong here
Global Tables are designed for multi-region writes.
- ✗
Strongly consistent reads across regions
Why it's wrong here
Global Tables do not support strongly consistent cross-region reads.
- ✓
Application tolerance for eventually consistent reads
Why this is correct
Cross-region replication is asynchronous; reads may be eventually consistent.
- ✓
Provisioning sufficient write capacity in each region
Why this is correct
Each region handles its own writes independently.
- ✓
Conflict resolution using last writer wins
Why this is correct
Global Tables use last writer wins to resolve concurrent updates.
