NEW QUESTION # 27
You have a on-premises Microsoft SQL Server named SQL1 that hosts five databases.
You need to migrate the databases to an Azure SQL managed instance. The solution must minimize downtime and prevent data loss.
What should you use?
Answer: A
Explanation:
Basic Concept: This question tests choosing the correct Azure migration approach by matching the source platform, target service, downtime tolerance, and administrative effort.
Why C is Correct: Database Migration Assistant is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. The scenario asks for: You need to migrate the databases to an Azure SQL managed instance. That makes Database Migration Assistant the option that satisfies the required Azure SQL layer and operational outcome.
Why A is Wrong: Log shipping is a SQL Server HA/DR technique that copies and restores log backups to a secondary database; it is more manual and operationally heavier for Azure SQL Managed Instance migration than LRS. It is not wrong technology in general, but it is the wrong HA/DR control for this scenario ' s failure model.
Why B is Wrong: Always On availability groups are SQL Server/SQL Managed Instance HA technology, not the Azure SQL Database PaaS failover abstraction used for database groups. It does not meet the failover, restore, quorum, or cross-region continuity target stated in the question, even if it is valid in a different availability design.
Why D is Wrong: Backup and Restore is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It is not wrong technology in general, but it is the wrong HA/DR control for this scenario ' s failure model.
