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.
