DBS-C01 Deployment and Migration Practice Question
A company wants to migrate an on-premises Oracle database to Amazon RDS for Oracle with minimal downtime. Which AWS service should be used for the migration?
⚠ Common exam trap
Test-takers frequently confuse AWS Schema Conversion Tool (SCT) as a full migration service, but SCT only handles schema conversion and must be paired with DMS for actual data movement, making DMS the correct answer for minimal downtime migration.
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
✓
AWS Database Migration Service (DMS)
AWS Database Migration Service (DMS) is the correct choice because it is specifically designed to migrate databases to AWS with minimal downtime by using ongoing replication (change data capture, CDC) from the source Oracle database to the target Amazon RDS for Oracle instance. DMS supports heterogeneous and homogeneous migrations, and for Oracle-to-Oracle migrations, it can use Oracle LogMiner or binary reader to capture changes continuously, allowing the source to remain operational during the migration.
