DBS-C01 Deployment and Migration Practice Question
A company wants to migrate a 10 TB Microsoft SQL Server database from on-premises to Amazon RDS for SQL Server. The migration must be completed within a week and minimize network bandwidth usage. Which approach is most suitable?
⚠ Common exam trap
The trap here is that candidates often overlook the physical transfer option (Snowball) for large migrations, mistakenly assuming that AWS DMS or Direct Connect can handle multi-terabyte datasets within tight deadlines without considering provisioning times or bandwidth constraints.

Correct answer & explanation
✓
Use AWS Snowball Edge to transfer backup files, then restore to RDS
AWS Snowball Edge is the most suitable approach because it allows you to transfer the 10 TB database backup files physically, bypassing the internet entirely. This eliminates network bandwidth constraints and ensures the migration can be completed within a week, as the data is shipped to AWS and then restored to Amazon RDS for SQL Server using native restore operations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Back up the database to Amazon S3 using AWS CLI
Why it's wrong here
S3 alone does not restore to RDS natively.
- ✗
Set up AWS Direct Connect and use DMS
Why it's wrong here
Direct Connect still uses network bandwidth.
- ✗
Use AWS DMS over the internet
Why it's wrong here
Would consume high bandwidth and may not complete in a week.
- ✓
Use AWS Snowball Edge to transfer backup files, then restore to RDS
Why this is correct
Snowball Edge bypasses network bandwidth constraints.
