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

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

2. You are designing a Windows application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
The business logic layer of the application is implemented by using Windows Communication Foundation (WCF).
You create a duplex bidirectional WCF service that contains a single operation. The service operation sends the result back to the client application by using a two-way callback operation.
You plan to design a service interaction strategy.
You need to ensure that deadlocks are prevented.
What should you do?

A) Configure the ServiceBehaviorAttribute attribute to use the Reentrant or Multiple concurrency mode in the service class.
B) Configure the CallbackBehaviorAttribute attribute to use the Reentrant or Multiple
concurrency mode in the callback class.
C) Configure the ServiceBehaviorAttribute attribute to use the Synchronization context in the service class.
D) Configure the CallbackBehaviorAttribute attribute to use the Synchronization context in the callback class.

3. You are designing a Windows Forms application.
You intend to display graphics on a form in the application by using a third-party Windows Presentation Foundation (WPF) control.
You need to recommend a control for hosting the third-party WPF control.
What should you recommend?

A) AnElementHost control
B) A Canvas control
C) A windowsFormsHost control
D) A Panel control

4. You are designing a Windows Presentation Foundation (WPF) application.
The application data files have the file name extension .abC.
The WPF application installer must meet the following requirements: - Add a shortcut to the desktop. - Install infrequently used assemblies on demand.
--
Associate the .abc file name extension with the WPF application. Roll back the installation in the event of a failure.
You need to recommend a deployment method.
What should you recommend?

A) Background Intelligent Transfer Service (BITS)
B) ClickOnce
C) Windows Installer
D) XCopy

5. You are upgrading a stand-alone Windows Presentation Foundation (WPF) application and an XAML browser application (XBAP) to Microsoft .NET Framework 4.
You plan to add .NET 4 types and members to both applications.
Both applications consume a common utility assembly that modifies files on a local file system. The utility assembly requires full trust.
You need to ensure that both applications can use the common utility assembly without any security-related exceptions.
What should you do?

A) Apply the AllowPartiallyTrustedCallersAttribute attribute to the utility assembly.
B) Change the <supportedRuntime> element for the XBAP application to the .NET Framework 3.5.
C) Change the <supportedRuntime> element for the WPF application to the .NET Framework 3.5.
D) Apply the AllowPartiallyTrustedCallersAttribute attribute to the XBAP application.
