Microsoft PRO: Design & Develop Wndws Apps Using MS .NET Framework 4 Sample Questions:

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

2. You are designing an n-tier solution that connects to a Microsoft SQL Server 2008 database.
You plan to deploy the database to development machines and to a staging database server from within Microsoft Visual Studio 2010.
You plan to set up separate build configurations for development and staging. You also plan to deploy to multiple production database servers managed by an outside vendor.
You must not allow the outside vendor to access the Visual Studio projects.
You need to recommend an approach for configuring and deploying the production database servers.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

A) Use SQL Server 2008 Management Studio to deploy the production databases.
B) Use a SQL Server 2008 Database Project.
C) Use a Visual C# SQL CLR Database Project.
D) Use VSDBCMD to deploy the production databases.

3. An existing Windows application uses a Windows Communication Foundation (WCF) Web service that is available only to employees.

B) Implement the WCF Web service as a REST service.
C) Modify the WCF Web service operations to accept the profile token as an additional parameter.
D) Use SOAP headers to pass the profile token to the service operations.

4. You are designing a Windows application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.

5. You are designing an n-tier Windows application by using Microsoft .NET Framework 4, Microsoft Visual Studio 2010, and Microsoft SQL Server 2008.
The application will replace an existing client/server application. The existing application was created by using Microsoft Visual Basic 6.0 and consists of a series of COM components that access a SQL Server database.
