DBS-C01 Workload-Specific Database Design Practice Question
A company is migrating an on-premises Oracle OLTP workload to AWS. The database has complex stored procedures and requires minimal code changes. Which AWS database service is the most suitable target?
⚠ Common exam trap
Test-takers frequently assume Aurora PostgreSQL is a drop-in replacement for Oracle due to its PostgreSQL compatibility features, but it still requires significant code changes for complex stored procedures, whereas RDS for Oracle avoids this entirely.

Correct answer & explanation
✓
Amazon RDS for Oracle
Amazon RDS for Oracle is the most suitable target because it provides native Oracle compatibility, allowing the existing complex stored procedures and PL/SQL code to run with minimal or no changes.
