DP-300 Plan and implement data platform resources Practice Question
You are a database administrator for a large financial services company. The company is migrating its on-premises SQL Server databases to Azure SQL Managed Instance. One of the databases, FinanceDB, is 2.5 TB in size and runs a critical application that requires high availability with automatic failover. The application uses database mail and SQL Agent jobs. During migration, you need to minimize downtime. Which deployment option should you choose?
⚠ Common exam trap
A common mix-up: candidates confuse Azure SQL Database with Azure SQL Managed Instance, overlooking that database mail and SQL Agent jobs are only supported in Managed Instance, not in single databases or Hyperscale.
Answer choices
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
✓
Deploy an Azure SQL Managed Instance in a failover group with a secondary in another region
Azure SQL Managed Instance supports database mail and SQL Agent jobs natively, and deploying it in a failover group with a secondary in another region provides automatic failover and high availability while minimizing downtime during migration. The 2.5 TB size is within Managed Instance limits, and the failover group enables a controlled, continuous-sync replication to the secondary, allowing a swift cutover with minimal data loss.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy an Azure SQL Database Hyperscale with geo-replication
Why it's wrong here
Hyperscale does not support SQL Agent.
- ✗
Deploy an Azure SQL Managed Instance with zone-redundant configuration
Why it's wrong here
Zone redundancy provides HA within a region but not automatic failover for DR.
- ✗
Deploy a single Azure SQL Database with Active Geo-Replication
Why it's wrong here
Single database does not support SQL Agent or database mail.
- ✓
Deploy an Azure SQL Managed Instance in a failover group with a secondary in another region
Why this is correct
Failover group provides automatic failover, supports all required features, and allows minimal downtime migration.
