You are designing a data access service backed by Microsoft SQL Server. Other developers will use your
service as a third-party service.
You have the following requirements:
*To reduce maintenance cost, you must write the minimal amount of code required for fulfilling the goals.
*The service must function with Microsoft and non-Microsoft technologies.
*The service must implement the WS-Security standards.
You need to design the service to meet the requirements.
Which approach should you recommend?

• A. Use a WCF service with multiple bindings.
• B. Use an ASP.NET Web service.
• C. Use an .ashx file to return an XML response over HTTPS.
• D. Use SQL Server XML Web services.

A Windows Communication Foundation (WCF) service is responsible for transmitting XML documents between systems. The service has the following requirements: *It must minimize the transmission size by attaching the XML document as is without using escape characters or base64 encoding. *It must interoperate with systems that use SOAP but are not built on the .NET platform. You need to configure the service to support these requirements. Which message encoding should you use?

• A. Binary message encoding
• B. Text message encoding with message version set to SOAP 1.2
• C. MTOM (Message Transmission Optimization Mechanism) message encoding
• D. Text message encoding with message version set to none

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The
application uses the ADO.NET Entity Framework to model entities. The application allows users to make
changes to entities while disconnected from the central data store.
You need to ensure that when the user connects to the central data store and retrieves new data, the
application meets the following requirements:
*Changes made to the local data store in disconnected mode are preserved.
*Entities that have already been loaded into the local data store, but have not been modified by the user,
are updated with the latest data.
What should you do?

• A. Call the Refresh method of ObjectContext by using the RefreshMode.ClientWins method.
• B. Call the query's Execute method by using the MergeOptions.OverwriteChanges option.
• C. Call the Refresh method of ObjectContext by using the RefreshMode.StoreWins option.
• D. Call the query's Execute method by using the MergeOptions.AppendOnly option.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create a Windows Communication Foundation (WCF) Data Services service. The service connects to a Microsoft SQL Server 2008 database. The service is hosted by an Internet Information Services (IIS) 6.0 Web server.
The application works correctly in the development environment. However, when you connect to the service on the production server, attempting to update or delete an entity results in an error. You need to ensure that you can update and delete entities on the production server. What should you do?

• A. Add the following line of code to the InitializeService method of the service. config.SetEntitySetAccessRule ("*",EntitySetRights.WriteDelete | EntitySetRights.WriteInsert);
• B. Configure IIS to allow the PUT and DELETE verbs for the .svc Application Extension.
• C. Add the following line of code to the InitializeService method of the service. config.SetEntitySetAccessRule ("*",EntitySetRights.WriteDelete | EntitySetRights.WriteMerge);
• D. Configure IIS to allow the POST and DELETE verbs for the .svc Application Extension.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application uses the ADO.NET Entity Framework to model entities. You need to create a database from your model. What should you do?

• A. Run the edmgen.exe tool in FromSSDLGeneration mode.
• B. Run the edmgen.exe tool in FullGeneration mode.
• C. Use the Generate Database Wizard in Visual Studio. Run the resulting script against a Microsoft SQL Server database.
• D. Use the Update Model Wizard in Visual Studio.
