CV0-004 Deployment Practice Question
A company is migrating a 50 TB on-premises SQL Server database to Amazon RDS for MySQL with minimal downtime. The schema must be converted from SQL Server to MySQL. Which combination of AWS services should the cloud architect use?
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 DMS and AWS Schema Conversion Tool (SCT)
AWS DMS can migrate data with minimal downtime using CDC. Schema Conversion Tool (SCT) converts the schema from SQL Server to MySQL. DMS then performs the ongoing replication.
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 DMS and AWS Schema Conversion Tool (SCT)
Why this is correct
AWS Schema Conversion Tool converts the SQL Server schema and objects to MySQL-compatible definitions, while AWS DMS performs the ongoing data replication. Together they satisfy the heterogeneous engine migration with minimal downtime that the scenario demands.
- ✗
AWS Database Migration Service (DMS) only
Why it's wrong here
DMS alone does not convert schema between different database engines.
- ✗
AWS Snowball and AWS DMS
Why it's wrong here
Snowball moves bulk data physically but cannot convert SQL Server schema to MySQL, and DMS alone handles replication, not heterogeneous schema translation. It is tempting for very large datasets where transfer time dominates, but SCT is required here for the schema conversion the stem demands.
- ✗
AWS DataSync and AWS Schema Conversion Tool (SCT)
Why it's wrong here
DataSync transfers files to AWS storage services, not into Amazon RDS for MySQL, so it cannot load the database. SCT converts the schema correctly, making this pairing tempting, yet DataSync lacks the database replication endpoint DMS provides for minimal-downtime cutover.
