DBS-C01 Workload-Specific Database Design Practice Question
A company is designing a disaster recovery plan for an Amazon DynamoDB table that stores critical session data. The table is provisioned with on-demand capacity. The recovery objective is to have the data available in another AWS Region within 15 minutes of a regional outage. Which design should they choose?
⚠ Common exam trap
Test-takers frequently confuse DynamoDB Global Tables with cross-Region Read Replicas (which exist in RDS but not DynamoDB) or assume that on-demand backups can meet a 15-minute RTO, ignoring the manual restore time and lack of continuous replication.
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
✓
Use DynamoDB Global Tables to replicate data across Regions.
DynamoDB Global Tables provide multi-Region, fully replicated tables with automatic conflict resolution, enabling active-active replication that meets the 15-minute recovery objective without manual intervention. Global Tables replicate data across Regions in sub-second latency, ensuring data availability within the required RTO during a regional outage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use DynamoDB on-demand backups and restore to another Region.
Why it's wrong here
Restoring from backup takes longer than 15 minutes.
- ✗
Use DynamoDB Streams to replicate data to a table in another Region via AWS Lambda.
Why it's wrong here
This approach may introduce latency and complexity.
- ✓
Use DynamoDB Global Tables to replicate data across Regions.
Why this is correct
Global Tables provide active-active replication across Regions.
- ✗
Create cross-Region Read Replicas for DynamoDB.
Why it's wrong here
DynamoDB does not support cross-region read replicas.
