Which synchronization method should you use?

You are a data architect. The data engineering team needs to configure a synchronization of data between an on-premises Microsoft SQL Server database to Azure SQL Database.

Ad-hoc and reporting queries are being overutilized the on-premises production instance.

The synchronization process must:

– Perform an initial data synchronization to Azure SQL Database with minimal downtime

– Perform bi-directional data synchronization after initial synchronization

You need to implement this synchronization solution.

A . transactional replication
B . Data Migration Assistant (DMA)
C . backup and restore
D . SQL Server Agent job
E . Azure SQL Data Sync
