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 small business wants to migrate their on-premises SQL Server database to Azure. They have limited budget and want to minimize ongoing management overhead. The database is less than 50 GB and is used by a single application with low concurrent users. The application requires compatibility with SQL Server features such as T-SQL, stored procedures, and functions. The business does not require high availability or disaster recovery. Which Azure relational database service 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.
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 (serverless tier)
Azure SQL Database serverless tier is the best choice because it provides a fully managed, PaaS relational database service that supports T-SQL, stored procedures, and functions, while automatically pausing during idle periods to reduce costs. With a database under 50 GB, low concurrency, and no HA/DR requirements, the serverless tier minimizes both management overhead and cost, as it charges only for compute used per second and storage consumed.
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.
✗
SQL Server on Azure Virtual Machines
Why it's wrong here
This option requires managing the VM and SQL Server, increasing overhead.
✓
Azure SQL Database (serverless tier)
Why this is correct
Serverless tier automatically pauses during inactivity, reducing cost, and requires minimal management.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Azure SQL Managed Instance
Why it's wrong here
Managed Instance is more expensive and provides features not needed for this small workload.
✗
Azure Database for MySQL
Why it's wrong here
MySQL is not compatible with SQL Server T-SQL and stored procedures.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose Azure SQL Managed Instance because of its full SQL Server compatibility, overlooking that the serverless tier of Azure SQL Database also supports T-SQL, stored procedures, and functions, and is far more cost-effective for small, low-usage workloads without HA/DR needs.
Detailed technical explanation
How to think about this question
The serverless tier of Azure SQL Database uses a compute auto-scaling model where the database pauses after 1 hour of inactivity (configurable) and resumes on the first connection, with a 1-minute cold start latency. This is ideal for intermittent workloads, as it bills compute per second (min 0.5 vCore) and storage separately, potentially reducing costs by 50-80% compared to provisioned tiers for low-usage scenarios. Under the hood, it leverages the same SQL Server engine as Managed Instance but with a simplified architecture that lacks features like zone-redundant HA and instance-scoped collation.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
