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

Quick Answer

The correct choice is Azure SQL Database because it directly supports cross-database queries within the same logical server through elastic queries and gives you full control over database-level collation settings, all while being a fully managed PaaS service that handles infrastructure patching automatically. For a migration under 1 TB with no need for instance-level features like SQL Agent jobs or linked servers, Azure SQL Database minimizes management overhead perfectly. On the DP-900 exam, this scenario tests your ability to distinguish between Azure SQL Database and Managed Instance—a common trap is assuming Managed Instance is always better for migrations, but the key differentiator is that Azure SQL Database excels when you need elastic cross-database queries and collation control without instance-level dependencies. Memory tip: think “Elastic and Collation = Database, not Instance”—if the requirement is about database-level flexibility rather than instance-level power, Azure SQL Database is your answer.

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 legacy on-premises database to Azure. They require the ability to run cross-database queries within the same logical server, full control over database collation settings, and want to minimize management overhead for infrastructure patching. The database size is under 1 TB and they do not need instance-level features like SQL Agent jobs or linked servers. Which Azure SQL offering should they choose?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.

A
Azure SQL Database
Azure SQL Database is a PaaS service that handles patching, supports elastic query for cross-database queries, and allows collation settings on a per-database level. It does not include SQL Agent or linked servers, which are not required here.
B
Azure SQL Managed Instance
Why wrong: SQL Managed Instance provides instance-scoped features like SQL Agent and linked servers, but also includes more management overhead and higher cost. Since those features are not needed, it is not the optimal choice.
C
SQL Server on Azure Virtual Machine
Why wrong: Running SQL Server on a VM provides full control but requires the customer to manage patching and backups, contradicting the goal of minimizing management overhead.
D
Azure Synapse SQL pool
Why wrong: Azure Synapse SQL is designed for data warehousing and analytics, not for general-purpose relational transactional workloads. It also does not support cross-database queries or per-database collation in the same way as Azure SQL Database.

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

✓

Azure SQL Database

Azure SQL Database is the correct choice because it supports cross-database queries within the same logical server via elastic queries, allows full control over database-level collation settings, and is a fully managed Platform-as-a-Service (PaaS) offering that handles infrastructure patching automatically. With a database size under 1 TB and no need for instance-level features like SQL Agent jobs or linked servers, Azure SQL Database meets all requirements while minimizing management overhead.

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 with Azure SQL Managed Instance, assuming that cross-database queries require instance-level features like linked servers, but Azure SQL Database supports this via elastic queries without the need for instance-level management.

Detailed technical explanation

How to think about this question

Azure SQL Database uses elastic database queries to enable cross-database queries within the same logical server by leveraging the external data source and external table syntax (CREATE EXTERNAL DATA SOURCE and CREATE EXTERNAL TABLE). Collation settings in Azure SQL Database are set at the database level using the COLLATE clause during creation, and cannot be changed at the server level, which aligns with the requirement for full control. The service automatically applies OS and SQL engine patches during its maintenance windows, typically using a rolling upgrade model to minimize downtime.

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.
