DEA-C01 Data Store Management Practice Question
A company is designing a disaster recovery strategy for an Amazon RDS for SQL Server database. The database must be recoverable in another AWS region within 15 minutes of a regional outage. Which TWO actions should the data engineer take?
⚠ Common exam trap
A common mix-up: candidates confuse Multi-AZ (regional high availability) with cross-region disaster recovery, or they assume automated backups can be copied across regions, but AWS does not support automatic cross-region backup copying for RDS.
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
✓
Configure automated cross-region snapshots to be copied to the recovery region.
Cross-region snapshots for Amazon RDS are automatically copied to a destination AWS region, enabling you to restore the database in the recovery region from the most recent snapshot. This meets the 15-minute recovery time objective (RTO) when combined with a pre-provisioned DB instance, as the snapshot copy is asynchronous but can be scheduled to occur frequently (e.g., every 5 minutes for SQL Server).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable Multi-AZ deployment on the primary instance.
Why it's wrong here
Multi-AZ is for high availability within a region, not disaster recovery.
- ✗
Configure automated backups to copy to the recovery region.
Why it's wrong here
RDS automated backups are region-specific; cannot be copied automatically.
- ✓
Configure automated cross-region snapshots to be copied to the recovery region.
Why this is correct
Cross-region snapshot copy allows restoring in another region.
- ✓
Create a cross-region read replica in the desired recovery region.
Why this is correct
Read replicas can be promoted to a primary instance in another region.
