You are developing a Windows application by using Microsoft .NET Framework 4, Microsoft Visual Studio 2010, and Microsoft SQL Server 2008.
New features that require changes to be made to the database schema are added to the application every week.
You need to ensure that the changes made to the database schema do not require the application to be recompiled.
Which two actions should you perform? (Each correct answer presents part of the solution.
Choose two.)

• A.Modify the conceptual schema xml file when the schema changes occur.
• B.Modify the xml mapping file when the schema changes occur.
• C.Build a conceptual model and use it to access data from the business entities.
• D.Build a storage model and use it to access data from the business entities.

You are designing a Windows Presentation Foundation (WPF) application that uses .NET Framework 4. The application uses a subset of the functionality provided by a third-party COM component that will be replaced later.
The application developers must have access to only the required subset of functionality.
You need to recommend a solution that meets the requirements.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

• A.Create an adapter assembly that exposes the entire functionality of the COM component.
• B.In the adapter assembly, use an embedded interop reference.
• C.In the adapter assembly, use a standard interop reference.
• D.Create an adapter assembly that exposes the required subset of the COM component functionality.

You are designing a .NET Framework 4 solution that includes a Windows Presentation Foundation (WPF) application. The WPF application connects to a Microsoft SQL Server 2008 database. You plan to deploy the WPF application to millions of client computers. The SQL Server database will be hosted in a data center.
The WPF application will query the database to provide type-ahead assistance as users enterdata.
The WPF application will send a query after each character is entered. Each query will access multiple joined tables.
You need to recommend an approach for maximizing scalability of the solution.
What should you recommend?

• A.Create stored procedures to abstract the tables.
• B.Create a separate data layer with caching.
• C.Denormalize the data to fewer tables.
• D.Use System.Runtime.Caching to cache query results on the client.

You are creating a Windows Presentation Foundation (WPF) application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
The application will consist of several data entry forms. Each data entry form requires a user to enter phone numbers and addresses.
You need to design a solution that promotes code reusability.
What should you do?

• A.Create a new merged resource dictionary and reference it from each data entry form.
• B.Create a new user control and reference it on each data entry form.
• C.Add multiple text boxes for each data entry form.
• D.Use the same style resource for each data entry form.

You are designing an application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
The application is used mostly in a disconnected scenario. The application requires offline data from a Microsoft SQL Server 2008 database. When the application connects to the network, data will be modified and synchronized.
You need to ensure that the application does not access the database server directly to synchronize data when online.
Which technology should you use?

• A.WCF Data Service
• B.Remote Data Access
• C.ADO.NET Sync Services
• D.SQL Server Merge Replication
