The answer is Azure SQL Managed Instance, SQL Server on Azure Virtual Machine, and Azure SQL Database elastic pool. These three options meet the requirements because they all support SQL Server Agent jobs—either natively or through elastic jobs—and enable cross-database queries, either directly or via elastic query, while allowing storage to scale independently from compute. On the DP-300 exam, this question tests your ability to map on-premises SQL Server features to Azure deployment models, with a common trap being to overlook that elastic pools support cross-database queries and Agent jobs through elastic jobs, not just Managed Instance. A key memory tip is to remember that the three "M" options—Managed Instance, VM, and elastic pool—all offer the "M" in minimal application changes, Agent support, and multi-database querying, whereas a single database or hyperscale would fail on Agent or cross-database needs.
DP-300 Plan and implement data platform resources Practice Question
This DP-300 practice question tests your understanding of plan and implement data platform resources. 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.
Your company is migrating several on-premises SQL Server databases to Azure. The databases range from 50 GB to 2 TB and have varying performance requirements. You need to decide which Azure SQL deployment options to use. The requirements include:
- Minimal application changes.
- Support for SQL Server Agent jobs.
- Ability to scale storage independently from compute.
- Native support for cross-database queries.
Which THREE options meet these requirements? (Choose three.)
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 elastic pool
Azure SQL Managed Instance (E) provides full SQL Server engine compatibility, including SQL Server Agent, cross-database queries, and independent storage scaling, with minimal application changes. SQL Server on Azure Virtual Machine (D) offers full control over the SQL Server instance, supporting Agent jobs and cross-database queries, and allows independent scaling of compute and storage via VM resizing and managed disks. Azure SQL Database elastic pool (B) supports SQL Server Agent jobs (via elastic jobs), independent storage scaling per database, and cross-database queries using elastic query, while requiring minimal application changes.
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 (single database)
Why it's wrong here
Does not support cross-database queries or SQL Server Agent.
✓
Azure SQL Database elastic pool
Why this is correct
Supports cross-database queries within pool and independent scaling, but not SQL Server Agent.

✗
Azure Synapse Analytics (dedicated SQL pool)
Why it's wrong here
Not suitable for OLTP workloads; does not support SQL Agent jobs.
✓
SQL Server on Azure Virtual Machine
Why this is correct
Supports all requirements but requires management of VM.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume Azure SQL Database (single database) supports SQL Server Agent natively, but it does not—only Managed Instance and VM provide full Agent support, and elastic pools require elastic jobs as a workaround.
Detailed technical explanation
How to think about this question
Azure SQL Managed Instance uses a native VNet deployment and provides a full SQL Server surface area, including CLR, Service Broker, and Database Mail, making it ideal for lift-and-shift migrations. SQL Server on Azure VM allows you to configure storage with Premium SSD or Ultra Disk, enabling independent scaling of IOPS and throughput from compute. Elastic pools in Azure SQL Database share resources among multiple databases, but each database can have its storage scaled independently, and elastic jobs can replace SQL Server Agent for scheduling.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
