DEA-C01 Data Store Management Practice Question
A company is migrating its on-premises MySQL database to Amazon RDS for MySQL. They want to minimize downtime and ensure data consistency. Which AWS service should be used for the migration?
⚠ Common exam trap
Candidates often confuse AWS DMS with AWS Glue, thinking both are for data migration, but Glue is for batch ETL and cannot perform live database replication with minimal downtime, while DMS is purpose-built for that task.

Correct answer & explanation
✓
AWS Database Migration Service (DMS)
AWS Database Migration Service (DMS) is the correct choice because it is specifically designed for migrating databases to AWS with minimal downtime. DMS supports homogeneous migrations like MySQL to Amazon RDS for MySQL, and it uses ongoing replication (change data capture) to keep the source and target databases in sync during the migration, ensuring data consistency and allowing a cutover with only seconds of downtime.
