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

1. You are designing an n-tier .NET Framework 4 solution that includes a Windows Presentation Foundation (WPF) application and a Windows Workflow Foundation (WF) component. The WF component contains functionality to incorporate frequently changing rules.
You need to recommend a tier for the deployment of the WF component that will not degrade the performance of the WPF application.
Which tier should you recommend?

A) The business tier
B) The presentation tier
C) The data tier
D) The data access tier

2. You are designing a Windows Presentation Foundation (WPF) client application that requests reports from a Windows Communication Foundation (WCF) Web service.
Users must be able to perform other tasks while the WCF Web service generates the report.
You need to recommend a message exchange pattern for the communication between the WPF application and the WCF Web service.
What are two possible message exchange patterns that will meet the requirements? (Each correct answer presents a complete solution, Choose two.)

A) Datagram without session
B) Request-Response
C) Duplex
D) Datagram with session

3. You are designing a Windows Presentation Foundation (WPF) application that will be used to display real-time data from a Microsoft SQL Server 2008 database.
You need to recommend an approach for displaying the datA.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

A) Use a SqlCacheDependency object in the data layer to query the database when a change is detected.
B) Implement OneWayToSource binding between the controls in the WPF application and objects in the data layer.
C) Implement OneWay binding between the controls in the WPF application and objects in the data layer.
D) Use a System.Runtime.Caching object in the data layer with a sliding expiration, and query the database when the Cache object expires.

4. You are developing an application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
You plan to use Microsoft Sync Framework to synchronize the data stored in a local Microsoft SQL Server Compact Edition database with the data stored in a centralized SQL Server 2008 database.
Four columns are added to each table involved in the synchronization process to track changes to the database. You add the following four columns to the database table.

Users report that the synchronization process is not always successful. You need to ensure that the application synchronizes data successfully. What should you do?

A) Option A
B) Option C
C) Option D
D) Option B

5. ---
You are designing a .NET Framework 4 solution. The solution contains a Windows Presentation Foundation (WPF) application and a Windows Communication Foundation (WCF) Web service.
The WPF application uses the WCF Web service to store data in a Microsoft SQL Server 2008 database.
You have the following requirements:
Ensure that the WPF application functions while users' computers are offline.
Minimize the time spent sending data to the WCF Web service.
Minimize disk space requirements for data storage.
You need to recommend an approach for synchronizing data between the WPF application and the database.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

A) Store data in custom business objects. Serialize data locally by using custom serialization.
B) Create a local caching solution that periodically checks for Internet connectivity and writes directly to the local data store and to the WCF Web service.
C) Create a local caching solution that periodically checks for Internet connectivity, uses local memory, and batches changes to the WCF Web service.
D) Store data in DataSet objects. Serialize data locally by using XML serialization.
