An on-premise .NET application uses an on-premise Microsoft SQL Server 2008 database.  The existing compute infrastructure is insufficient to support peak loads.   You plan to move only the compute-intensive component of the application into Windows Azure.  The component requires access to the on-premise database.   The on-premise database cannot be accessed from outside the network boundary.  You need to recommend a database topology.  What should you recommend？（）

• A、 Use SQL Azure for the on-premise components and the compute-intensive component.
• B、 Configure merge replication with the on-premise database as publisher and the SQL Azure database as subscriber.
• C、 Configure snapshot replication with the on-premise database as publisher and the SQL Azure database assubscriber.
• D、 Configure snapshot replication with the SQL Azuredatabase as publisher and the on-premise database as subscriber.
