DBS-C01 Deployment and Migration Practice Question
A company wants to migrate a 200 GB SQL Server database to Amazon RDS for SQL Server with minimal downtime. The database is used by a critical application. Which service should be used for the migration?
⚠ Common exam trap
It's easy for candidates to confuse AWS SCT (schema conversion) with AWS DMS (data migration), assuming SCT can also handle data movement, when in fact SCT only converts schema and assesses compatibility, while DMS handles the actual data transfer and ongoing replication.
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 DMS is the correct choice because it supports ongoing replication (change data capture) from a SQL Server source to an Amazon RDS for SQL Server target, enabling a migration with minimal downtime. DMS can perform a full load of the 200 GB database and then continuously replicate changes until the cutover, which is essential for a critical application that cannot tolerate extended downtime.
