DP-300 Plan and implement data platform resources Practice Question
Your company is migrating an on-premises SQL Server database to Azure SQL Managed Instance. The database is 2 TB in size and has multiple logins, jobs, and SQL Server Agent alerts. You need to choose a migration method that minimizes downtime and preserves all server-level objects. Which approach should you recommend?
⚠ Common exam trap
It's easy for candidates to assume backup/restore (Option D) is sufficient for a full migration, overlooking that server-level objects like logins and jobs are not included in the backup file and must be migrated separately, leading to incomplete environment preservation.

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
✓
Use Azure Database Migration Service with online migration
Azure Database Migration Service (DMS) with online migration is the correct choice because it supports minimal downtime by continuously synchronizing changes from the source SQL Server to the target Azure SQL Managed Instance until cutover. It also automatically migrates server-level objects such as logins, jobs, and SQL Server Agent alerts, which are critical for preserving the full environment. This method is designed for large databases (2 TB) and provides a managed, resilient migration pipeline.
