An on-premise application is exposed to external users through a Windows Communication Framework （WCF） service endpoint registered in the Windows Azure AppFabric Service Bus.  You need to recommend an approach for providing transport-level security that maximizes performance and minimizes bandwidth requirements. 
What should you recommend？（）

单项选择题You are designing an application that will interact with non-Windows applications over unreliable connections.   Each non-Windows application will have its own security token.   You need to recommend an approach for non-Windows applications to retrieve messages.  What should you recommend？（）

A. Retrieve messages from a Windows Azure Queue.
B. Retrieve messages from Windows Azure Table storage.
C. Retrieve messages from a blob storage container that has a private access policy.
D. Retrieve messages from the Windows Azure AppFabric Service Bus message buffer.

单项选择题Multiple Windows Azure applications connect to multiple SQL Azure servers.  On-premise users connect to the SQL Azure servers for a variety of purposes.   You successfully deploy a new Windows Azure application with its own SQL Azure server.  When on- premise users attempt to connect to the new SQL Azure server they receive connection errors.   You need to recommend an approach for mitigating the connectivity issue.  What should you recommend？ （）

A. Open port 1433 on the network firewall.
B. Use Security Support Provider Interface （SSPI）.
C. Disable the validation of the SSL certificate for the SQL Azure server through theconnection string.
D. Change the firewall rules of the new SQL Azure server to allow access by computers on the internalnetwork.

单项选择题You are designing a Windows Azure web application.   The application must integrate with on-premise business services.   The business services are running on an on-premise server and cannot be rewritten. The business services are not exposed externally.   You need to recommend an approach for accessing the business services.  What should you recommend？（）

A. Move business service functionality to Windows Azure.
B. Connect to the on-premise server from a custom service in Windows Azure.
C. Create a VPN connection between the application and the on-premise server.
D. Expose the business services to the Windows Azure AppFabricService Bus by using a custom service that configures relay binding.

单项选择题Your company hosts web services in the company intranet.  The intranet is secured by a firewall.   Devices outside the firewall must be able to access the web services.  Company policies prohibit changes to firewall rules.  You need to recommend an approach for enabling inbound communication.  What should you recommend？（）

A. Use Windows Server AppFabric.
B. Use the Windows Azure AppFabric Service Bus.
C. Use the Windows Azure AppFabric Access Control Service.
D. Use a Windows Communication Foundation （WCF） service in a Windows Azure role that relays to the internal web service

单项选择题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.
