DEA-C01 Data Store Management Practice Question
A data engineer is designing a multi-Region disaster recovery solution for an Amazon DynamoDB table. The table must be available in a secondary Region with minimal data loss and automatic failover. Which feature should be used?
⚠ Common exam trap
Many exam-takers confuse point-in-time recovery (PITR) with cross-Region disaster recovery, but PITR is a single-Region feature that does not provide automatic failover or multi-Region 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
✓
DynamoDB global tables
DynamoDB global tables provide a fully managed, multi-Region, multi-active database solution that replicates data automatically across selected AWS Regions. This ensures automatic failover with eventual consistency and minimal data loss, meeting the disaster recovery requirements for high availability and automatic failover without manual intervention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
DynamoDB on-demand backup and restore in the secondary Region
Why it's wrong here
Backup and restore is manual and not real-time.
- ✓
DynamoDB global tables
Why this is correct
Global tables replicate data across Regions and support automatic failover.
- ✗
DynamoDB point-in-time recovery (PITR)
Why it's wrong here
PITR allows restore to any point in time but is single-Region.
- ✗
DynamoDB cross-Region snapshot export to S3
Why it's wrong here
Export to S3 is not automatic failover.
