DBS-C01 Deployment and Migration Practice Question
Which TWO AWS services can be used together to migrate an on-premises MySQL database to Amazon Aurora MySQL with minimal downtime? (Select TWO.)
⚠ Common exam trap
It's easy for candidates to assume a single service like DMS alone can handle schema conversion, but DMS does not convert incompatible schema objects — that is the specific role of SCT, and both are required for a complete migration with minimal downtime.

Correct answer & explanation
✓
AWS Schema Conversion Tool (SCT)
AWS Database Migration Service (DMS) can perform continuous replication from an on-premises MySQL source to an Amazon Aurora MySQL target using change data capture (CDC), enabling near-zero downtime. The AWS Schema Conversion Tool (SCT) is used to assess and convert the source schema, including any incompatible objects, to ensure the Aurora target is ready for migration. Together, SCT handles schema transformation while DMS handles the ongoing data replication.
