The answer is the requirement for cross-database queries and the need for SQL Server Agent support. When migrating a legacy application, Azure SQL Managed Instance provides full SQL Server Agent functionality for scheduled jobs and automation, while Azure SQL Database lacks this feature entirely, making Managed Instance the correct choice for legacy workloads that depend on it. Additionally, cross-database queries are natively supported in Managed Instance but require complex workarounds in Azure SQL Database, which operates in a contained database model. On the Microsoft Azure Data Engineer Associate DP-203 exam, this question tests your ability to distinguish between PaaS offerings based on legacy compatibility, with a common trap being to assume all SQL Server features transfer to Azure SQL Database. Remember the memory tip: “Agent and cross-database queries demand Managed Instance; for everything else, Database may suffice.”
DP-203 Design and implement data storage Practice Question
This DP-203 practice question tests your understanding of design and implement data storage. 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.
Which TWO factors should you consider when choosing between Azure SQL Database and Azure SQL Managed Instance for migrating a legacy application? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Need for SQL Server Agent jobs
Option C is correct because SQL Managed Instance includes full support for SQL Server Agent, which is essential for legacy applications that rely on scheduled jobs, alerts, or automation. Azure SQL Database does not support SQL Server Agent, making Managed Instance the appropriate choice when this feature is required.
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.
✗
Support for active geo-replication
Why it's wrong here
B is wrong because both support geo-replication.
✗
Authentication using Microsoft Entra ID
Why it's wrong here
E is wrong because both support Microsoft Entra ID authentication.
✓
Need for SQL Server Agent jobs
Why this is correct
A is correct because SQL Database does not have SQL Agent; Managed Instance does.

✓
Requirement for cross-database queries
Why this is correct
C is correct because Managed Instance supports cross-database queries within the instance, while SQL Database requires elastic queries.

✗
Integration with Azure VNet
Why it's wrong here
D is wrong because both support VNet integration.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume VNet integration (Option E) is exclusive to Managed Instance, but Azure SQL Database also supports VNet integration via private endpoints, making it a non-differentiating factor for this migration decision.
Detailed technical explanation
How to think about this question
SQL Server Agent in Managed Instance provides native job scheduling, alerting, and operator capabilities identical to on-premises SQL Server, which many legacy applications depend on for ETL, maintenance, or monitoring tasks. Azure SQL Database lacks SQL Server Agent entirely, requiring alternative solutions like Azure Automation or Elastic Jobs, which may not support legacy job scripts or dependencies. Cross-database queries (Option D) are also a critical differentiator: Azure SQL Database restricts cross-database queries to elastic query or external tables, while Managed Instance supports full cross-database queries and linked servers, matching on-premises behavior.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
