Microsoft 070-518 Exam Syllabus Topics:

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

Question 1

You are designing a Windows Presentation Foundation (WPF) application by using Microsoft .NET Framework 4, Microsoft Visual Studio 2010, and Microsoft SQL Server 2008.
You have designed the application to use the ADO.NET Entity Framework for the Data Access Layer (DAL).
You have designed the user interface (UI) of the application by using the Model-View-ViewModel (M-V-VM) pattern.
The middle tier of the application is designed by using Windows Communication Foundation (WCF).
The database schema changes often. The DAL entity objects are required to be referenced from the middle tier and the ViewModel layer of the UI.
You need to ensure that the DAL entity objects are updated when the database schema changes.
What should you do?

A. Create typed DataSets.
B. Create persistent-aware objects.
C. Create an observable collection of objects.
D. Create persistent-ignorant objects.

Question 2

You are designing a .NET Framework 4 solution that includes a Windows Presentation Foundation (WPF) application, a Windows service, and a private assembly shared by the WPF application and by the Windows service.
The solution stores data in a local Microsoft SQL Server Compact 3.5 database. The WPF application and Windows service will each access the database directly. The solution will be installed by using Windows Installer.
You have the following requirements:
- The installer must allow users to specify the installation folders for the WPF application and for the database. - The solution must support the deployment of updates to the WPF application without restarting the Windows service.
You need to recommend an approach for installing the solution.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

A. In the installer, create a registry key that stores the WPF application installation path.
B. In the installer, set an environment variable that defines the database installation path.
C. Install the Windows service to a different folder from the WPF application.
D. Install the Windows service to the same folder as the WPF application.

Question 3

You are designing a Windows Presentation Foundation (WPF) application that connects to a data access layer on a server.
You have the following requirements for all security-related exceptions:
- Exceptions that occur in the data access layer must be handled in a single exception handler in the WPF application. - Exceptions must pass customized messages back to the WPF application.
You need to recommend an approach for creating new exception classes in the data access layer.
From which class should you inherit?

A. System.AccessViolattonException
B. System.ApplicationException
C. System.Security.SecurityException
D. System.InvalidOperationException

Question 4

You are reviewing multiple Windows Presentation Foundation (WPF) applications that capture postal addresses. The WPF applications have different appearances and functionality. Each WPF application uses a different control to visualize the captured addresses.
You plan to modify all WPF applications to allow developers to visualize addresses by using a common template.
You need to recommend an approach for standardizing the visualization of captured addresses.
What should you recommend?

A. Use a DataTemplate object.
B. Use a FrameworkTemplate object.
C. Use an ItemsPanelTemplate object.
D. Use a ControlTemplate object.

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