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 plans to migrate a 2-TB on-premises SQL Server database to Azure. The database uses SQL Server Agent jobs for scheduled maintenance and requires automatic failover across Azure regions. The company wants a fully managed service with minimal application changes. Which Azure SQL service should they choose?
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 correct because it provides near 100% compatibility with SQL Server, including support for SQL Server Agent jobs, and offers automatic failover across Azure regions via failover groups. It is a fully managed service that requires minimal application changes, unlike Azure SQL Database which lacks SQL Server Agent and has limited cross-region failover capabilities.
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.
✗
Azure SQL Database
Why it's wrong here
Azure SQL Database does not support SQL Server Agent jobs, which is a requirement for scheduled maintenance.
✓
Azure SQL Managed Instance
Why this is correct
SQL Managed Instance supports SQL Server Agent, can scale up to 16 TB, and provides auto-failover groups for cross-region high availability.
Related concept
Read the scenario before looking for a memorised answer.
✗
SQL Server on Azure Virtual Machines
Why it's wrong here
While it supports SQL Server Agent, it requires manual patching and management, not a fully managed service.
✗
Azure Synapse Analytics
Why it's wrong here
Azure Synapse Analytics is a data warehouse solution not designed for transactional workloads with SQL Agent jobs.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose Azure SQL Database because it is the most well-known fully managed service, overlooking the specific requirement for SQL Server Agent jobs and automatic cross-region failover, which Managed Instance uniquely supports.
Detailed technical explanation
How to think about this question
Azure SQL Managed Instance uses a native virtual network (VNet) deployment, enabling seamless connectivity and support for SQL Server Agent, Service Broker, and cross-database queries. Failover groups in Managed Instance leverage automatic geo-replication with a readable secondary replica in a paired region, providing RPO of 5 seconds and RTO of 1 hour during regional outages. This contrasts with Azure SQL Database's elastic pools, which require sharding for similar cross-region failover and lack Agent job support.
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.
