The answer is Data Migration Assistant (DMA) and Azure Migrate. 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, generating a report of feature parity, breaking changes, and behavior differences. Azure Migrate complements this by providing a broader discovery and readiness assessment across your environment, helping to inventory servers and validate dependencies before migration. On the DP-300 exam, this question tests your understanding of the assessment phase in the migration lifecycle, often appearing as a multi-select item where candidates mistakenly choose Azure Database Migration Service (which handles the actual migration, not the pre-migration compatibility check). A common trap is confusing assessment tools with migration tools—remember that DMA and Azure Migrate are for the "assess" stage, while DMS is for the "migrate" stage. Memory tip: "Assess with DMA, Migrate with DMS."
DP-300 Plan and implement data platform resources Practice Question
This DP-300 practice question tests your understanding of plan and implement data platform resources. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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.)
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, enabling you to remediate issues before migration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Data Migration Assistant (DMA)
Why this is correct
DMA assesses SQL Server compatibility with Azure SQL Managed Instance.
Related concept
Read the scenario before looking for a memorised answer.
✗
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.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing 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.
Detailed technical explanation
How to think about this question
DMA uses a rules-based engine that checks over 1000 compatibility rules against the source database, covering areas like deprecated features, syntax changes, and unsupported data types for Azure SQL Managed Instance. It also provides a 'feature parity' report that highlights features like SQL Agent jobs or Service Broker that may need reconfiguration. In a real-world scenario, DMA can assess multiple databases in a single session and output a JSON or Excel report for tracking remediation progress.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
