SAP-C02 Design for New Solutions Practice Question
A company is designing a multi-region disaster recovery solution for a critical application using Amazon RDS for MySQL. They need a Recovery Point Objective (RPO) of less than 5 seconds and a Recovery Time Objective (RTO) of less than 1 minute. Which solution should they choose?
⚠ Common exam trap
Test-takers frequently confuse Amazon Aurora Global Database (which is not available for RDS MySQL) with RDS cross-Region replicas, or assume Multi-AZ can be configured across Regions, which is technically impossible.
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 Amazon RDS with cross-Region read replicas and promote the replica to a primary instance in a disaster.
Amazon RDS for MySQL cross-Region read replicas use asynchronous replication with a typical lag of less than 5 seconds, meeting the RPO requirement. In a disaster, you promote the replica to a standalone primary instance, which takes under 1 minute, satisfying the RTO. This is the only option that provides both sub-5-second RPO and sub-1-minute RTO for RDS MySQL.
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 Amazon RDS with cross-Region read replicas and promote the replica to a primary instance in a disaster.
Why this is correct
Cross-Region read replicas use asynchronous replication with minimal lag, and can be promoted quickly, meeting the RPO/RTO requirements.
- ✗
Use Amazon Aurora Global Database.
Why it's wrong here
Aurora Global Database is for Aurora, not RDS MySQL.
- ✗
Use Amazon RDS with automated backups and restore in another Region.
Why it's wrong here
Restoring from backup would take longer than 1 minute, not meeting the RTO.
- ✗
Use Amazon RDS Multi-AZ with a standby in a different AWS Region.
Why it's wrong here
RDS Multi-AZ only supports standby in the same region, not cross-region.
