SAP-C02 Design for New Solutions Practice Question
A company is designing a new application that requires a relational database with automated backups and multi-AZ redundancy. The database workload is predictable with occasional read replicas for reporting. Which AWS service should be used?
⚠ Common exam trap
It's easy for candidates to confuse Amazon Redshift's columnar storage and read replica-like features (e.g., concurrency scaling) with a relational database, but Redshift is not designed for transactional workloads or automated Multi-AZ failover.
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
✓
Amazon RDS
Amazon RDS is the correct choice because it provides managed relational databases (e.g., MySQL, PostgreSQL, Oracle, SQL Server) with built-in automated backups and Multi-AZ redundancy for high availability. The workload is predictable and requires occasional read replicas for reporting, both of which are natively supported by RDS without the need for complex configuration.
