DBS-C01 Deployment and Migration Practice Question
A company is migrating a 10 GB MySQL database to Amazon RDS for MySQL. They have a 1 Gbps connection to AWS. The migration must be completed in the least amount of time with minimal manual effort. Which tool should be used?
⚠ Common exam trap
A common mix-up: candidates choose mysqldump (Option C) because it is familiar and free, but they overlook the requirement for minimal manual effort and the need for continuous replication, which DMS provides automatically.

Why each option matters

Correct answer & explanation
✓
AWS Database Migration Service (DMS).
AWS Database Migration Service (DMS) is the correct choice because it can perform a live, continuous migration of a 10 GB MySQL database to Amazon RDS for MySQL with minimal downtime and manual effort. DMS handles schema conversion (if needed), data replication, and ongoing changes via Change Data Capture (CDC), allowing the migration to complete in the least amount of time while automatically managing the full load and sync process over the 1 Gbps connection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Schema Conversion Tool (SCT).
Why it's wrong here
SCT converts schema, not data.
- ✗
AWS Snowball Edge.
Why it's wrong here
A 10 GB database can be transferred over a 1 Gbps connection in minutes, making physical shipment of a Snowball Edge device far slower than direct network transfer. Snowball Edge is designed for offline bulk data migration when bandwidth is limited or unavailable, not for small datasets over fast links. Its use would introduce unnecessary shipping and staging delays, contradicting the requirement for minimal time and manual effort.
- ✗
mysqldump and mysql command-line tools.
Why it's wrong here
While functional, this requires manual steps and the database must be offline during export.
- ✓
AWS Database Migration Service (DMS).
Why this is correct
DMS automates the migration process and can complete quickly over high bandwidth.
