SAP-C02 Design for New Solutions Practice Question
A company is designing a new application on AWS that requires high availability and disaster recovery across multiple AWS Regions. The application uses an Amazon RDS for MySQL database. Which TWO strategies should they implement to meet these requirements?
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
✓
Enable automated backups and copy them to another Region.
The correct answers are B and D. Option B enables automated backups of the RDS instance and copies them to another region, allowing point-in-time restoration in a different region for disaster recovery. Option D creates a cross-Region read replica, which serves as a standby database in another region for DR and also offloads read traffic. Option A (manual snapshot) requires manual effort and scheduling, not automated. Option C (S3 cross-Region replication) does not apply to RDS database backups. Option E (Multi-AZ) provides high availability within a single region but not across 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.
- ✗
Create a manual snapshot and copy it to another Region.
Why it's wrong here
Manual process, not automated DR.
- ✓
Enable automated backups and copy them to another Region.
Why this is correct
Cross-Region backup copy enables restore in another region.
- ✗
Use S3 cross-Region replication for the database.
Why it's wrong here
S3 replication is for S3 objects, not RDS.
- ✓
Configure a cross-Region read replica.
Why this is correct
Provides DR and read scaling across regions.
- ✗
Enable Multi-AZ deployment.
Why it's wrong here
Multi-AZ provides HA within a region, not DR.

| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
