You have an app named App1 that uses data from two on-premises Microsoft SQL Server databases named DB1 and DB2.
You plan to move DB1 and DB2 to Azure.
You need to implement Azure services to host DB1 and DB2. The solution must support server-side transactions across DB1 and DB2.
Solution: You deploy DB1 and DB2 as Azure SQL databases on the same Azure SQL Database server.
Does this meet the goal?
A . Yes
B . No
Answer: B
Explanation:
Instead deploy DB1 and DB2 to SQL Server on an Azure virtual machine.
Note: Understanding distributed transactions.
When both the database management system and client are under the same ownership (e.g. when SQL Server is deployed to a virtual machine), transactions are available and the lock duration can be controlled.
