DP-300 Plan and implement data platform resources Practice Question
You are planning a migration of on-premises SQL Server databases to Azure SQL Managed Instance. Which TWO tools or services can you use to assess compatibility and identify potential migration blockers? (Select TWO.)
⚠ Common exam trap
Many exam-takers confuse the assessment tool (DMA) with the migration execution tool (DMS) or assuming that SSMS or Azure Data Studio wizards provide the same depth of compatibility analysis, when in fact DMA is the dedicated assessment tool for Azure SQL Managed Instance migrations.

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
✓
Data Migration Assistant (DMA)
Data Migration Assistant (DMA) is the correct tool because it performs a detailed assessment of on-premises SQL Server databases, identifying compatibility issues and migration blockers specifically for Azure SQL Managed Instance. It generates a report of feature parity, breaking changes, and behavior differences. Azure Migrate is also correct because it provides a unified migration assessment and discovery platform, including database assessment capabilities for Azure SQL targets. Both tools can assess compatibility and identify blockers before migration.

- ✓
Data Migration Assistant (DMA)
Why this is correct
DMA assesses SQL Server compatibility with Azure SQL Managed Instance.
- ✗
SQL Server Management Studio (SSMS) – Upgrade Data Tier Application wizard
Why it's wrong here
This wizard is for database deployments, not compatibility assessment.
- ✗
Azure Database Migration Service (DMS)
Why it's wrong here
DMS is for migration execution, not assessment.
- ✓
Azure Migrate
Why this is correct
Azure Migrate can assess SQL Server instances for migration readiness.
- ✗
Azure Data Studio – Migration Wizard
Why it's wrong here
Migration Wizard is for migration, not assessment.
Quick reference
RAID Level Comparison
| RAID Level | Min Disks | Fault Tolerance | Read | Write | Usable Capacity |
|---|---|---|---|---|---|
| RAID 0 | 2 | None | Excellent | Excellent | 100% |
| RAID 1 | 2 | 1 disk | Good | Moderate | 50% |
| RAID 5 | 3 | 1 disk | Good | Moderate | 67–94% |
| RAID 6 | 4 | 2 disks | Good | Lower | 50–88% |
| RAID 10 | 4 | 1 disk per mirror | Excellent | Good | 50% |
RAID is not a backup strategy — it protects against disk failure but not against accidental deletion, ransomware, or site-level events.
