DP-900 Practice Question: Identify considerations for relational data on Azure
This DP-900 practice question tests your understanding of identify considerations for relational data on azure. 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.
A company is migrating a 500 GB on-premises SQL Server database to Azure. The database uses SQL Server Agent for scheduled maintenance jobs and requires the ability to run cross-database queries within the same logical server. The company wants a PaaS service that minimizes management overhead for patching and backups while preserving these SQL Server features. Which Azure SQL service should they choose?
Why wrong: Azure SQL Database is a single database PaaS offering but does not support SQL Server Agent or cross-database queries within the same server.
B
Azure SQL Managed Instance
Azure SQL Managed Instance provides full SQL Server compatibility including SQL Server Agent and cross-database queries, with managed patching and backups.
C
SQL Server on Azure Virtual Machine
Why wrong: SQL Server on an Azure VM is IaaS, requiring the company to manage patching and backups, not minimizing management overhead.
D
Azure Database for MySQL
Why wrong: Azure Database for MySQL is a different database engine and does not support SQL Server features like Agent or cross-database queries.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure SQL Managed Instance
Azure SQL Managed Instance is the correct choice because it provides near 100% compatibility with on-premises SQL Server, including SQL Server Agent and cross-database queries within the same instance. As a PaaS service, it handles patching and backups automatically, minimizing management overhead while preserving these required features.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure SQL Database's 'logical server' with a true SQL Server instance, assuming it supports SQL Server Agent and cross-database queries, when in fact it does not.
Detailed technical explanation
How to think about this question
Azure SQL Managed Instance runs in a dedicated virtual network and uses the same TDS protocol as SQL Server, enabling features like SQL Server Agent jobs, cross-database queries, and linked servers. Under the hood, it leverages a shared disk architecture with automatic backups and patching, but still allows full instance-level control. In a real-world scenario, a company migrating a 500 GB database with scheduled maintenance jobs would benefit from Managed Instance's native support for SQL Agent without needing to rewrite jobs as elastic jobs.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
