Question 318 of 982

Identify considerations for relational data on Azure →mediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is Azure SQL Managed Instance. This is the correct choice because it offers near 100% compatibility with on-premises SQL Server, including full support for SQL Server Agent jobs for scheduled maintenance and linked servers to query remote instances, while also providing automated backups and patching—allowing migration with minimal application changes. On the DP-900 exam, this scenario tests your understanding of when to choose Azure SQL Managed Instance for migration, specifically distinguishing it from Azure SQL Database (which lacks Agent and linked server support) and SQL Server on Azure VMs (which requires manual patching). A common trap is assuming SQL Database can handle Agent jobs, but it cannot; Managed Instance is the only PaaS option that preserves these features. Memory tip: think "Managed Instance = Managed Compatibility" for Agent and linked servers.

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 has an existing on-premises SQL Server database that is 500 GB in size. The database uses SQL Server Agent jobs for scheduled maintenance and linked servers to query data from a remote SQL Server instance. The company wants to migrate to Azure with minimal application changes and needs automated backups and patching. Which Azure SQL service should they choose?

A
Azure SQL Database
Why wrong: Azure SQL Database is a fully managed PaaS offering, but it does not support SQL Agent jobs or linked servers. The company would need to redesign those features, which contradicts the requirement for minimal changes.
B
Azure SQL Managed Instance
Azure SQL Managed Instance provides high compatibility with on-premises SQL Server, including support for SQL Agent jobs and linked servers. It also includes automated backups, patching, and high availability, meeting all requirements.
C
SQL Server on Azure Virtual Machines
Why wrong: SQL Server on Azure VMs gives full control but requires the company to manage backups, patching, and high availability manually. This does not meet the requirement for automated backups and patching.
D
Azure Database for PostgreSQL
Why wrong: Azure Database for PostgreSQL is a different database engine (PostgreSQL, not SQL Server). The company would need to perform a full migration, including changing application code and database schema, which is not minimal.

Correct answer & explanation

✓

Azure SQL Managed Instance

Azure SQL Managed Instance is correct because it provides near 100% compatibility with on-premises SQL Server, including support for SQL Server Agent jobs and linked servers, while offering automated backups and patching. This minimizes application changes during migration, unlike other Azure SQL options that lack these 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 choose Azure SQL Database for its simplicity, overlooking its lack of SQL Server Agent and linked server support, which are critical for the described workload.

Detailed technical explanation

How to think about this question

Azure SQL Managed Instance uses a fully managed SQL Server engine in a virtual network, enabling linked servers via TDS endpoints and SQL Server Agent via the same agent subsystem as on-premises. Under the hood, it leverages the same database engine as SQL Server 2019+, ensuring compatibility with existing T-SQL scripts and maintenance plans, while automated backups use Azure Blob Storage with point-in-time restore capabilities.

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.

Variation 1. A company has 15 on-premises SQL Server databases, each 20–40 GB, running on a single instance. They rely on cross-database queries using three-part names (e.g., DB1.dbo.table) and SQL Server Agent for maintenance. They want to migrate to Azure with minimal application changes and reduce administrative overhead. Which Azure SQL deployment option should they choose?

medium

A.Azure SQL Database elastic pool
B.Azure SQL Database single database
✓ C.Azure SQL Managed Instance
D.SQL Server on Azure Virtual Machines

Why C: Azure SQL Managed Instance is correct because it provides near-100% compatibility with on-premises SQL Server, including support for cross-database queries using three-part names and SQL Server Agent. This allows the company to migrate with minimal application changes while offloading administrative overhead like patching and backups, which are handled by Azure.
