문제 #1

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.
You plan to move the existing COM components into a Windows Communication Foundation (WCF) tier.
You need to ensure that the COM components can be replaced without impacting the existing user interface (UI) tier.
You also need to ensure that the COM components can be replaced separately.
What should you do?

A. Create a common assembly on the UI tier of the new application to interface with the COM components.
B. Use .NET COM Interop on the client tier to interact directly with the COM components until they are replaced by the managed code.
C. Create a common assembly on the WCF tier of the new application to interface with the COM components.
D. Convert the Visual Basic 6.0 source code to managed code by using the Visual Studio converters. Use these code components on the client/server application until they are replaced individually with the new permanent managed code functionality.

문제 #2

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 presentation tier
B. The data access tier
C. The data tier
D. The business tier

문제 #3

You are designing a new feature for an existing Windows Forms application by using Microsoft .NET Framework 4.
The application contains multiple forms that are loaded into a parent Multiple Document Interface (MDI) form. Your company policy does not allow the use of third-party controls.
You need to ensure that the new feature meets the following requirements: - It provides a three-dimensional scale model.
- It allows users to change the colors of the model and communicates the color
selections back to the application. - It allows the model to scale, based on the user's client computer display resolution. - It is a child form in the MDI application.
What should you do?

A. Design the new feature in a new application by using Windows Presentation Foundation (WPF).
Invoke the new WPF application from the existing Windows Forms application.
B. Design the new feature in the existing Windows Forms application as a Windows form.
Add the form as a child form to the MDI window.
C. Design the new feature in a new Windows Presentation Foundation (WPF) application.
Host the existing application inside the new WPF application by using the WindowsFormsHost class
D. Design the new feature by using a Windows Presentation Foundation (WPF) user control.
Use the ElementHost class to host the WPF user control in the existing Windows Forms application.

문제 #4

You are designing an update to an existing Windows Presentation Foundation (WPF) application. You plan to use Microsoft Visual Studio 2010. The updated WPF application will require a specific version of a third-party component.
You have the following requirements:
- Deploy the update by using Windows Installer. - Update the WPF application only if the required version of the third-party component is present on the client computer.
You need to recommend configuration settings for the application installer.
Which property should you recommend be set?

A. TheRemovePreviousVersions property of the Setup Project
B. The Version property of the .NET Launch Condition
C. The Version property of the Setup Project
D. The Condition property of a new Launch Condition

문제 #5

You are working with an existing Windows Presentation Foundation (WPF) application in Microsoft Visual Studio 2010. The WPF application requires approximately one minute to initialize before displaying its main window.
You have the following requirements:
---
Immediately display a splash screen when the WPF application launches. Allow for the display of an initialization progress bar on the splash screen. Close the splash screen when the WPF application is ready to display the main window.
You need to recommend an approach for meeting the requirements.
What should you recommend?

A. Move the initialization code to the code-behind of the main window.
B. Create a SplashScreen object. Display the object in the code-behind of the App.xaml file.
C. Compile an image into the WPF application with a Build Action value of SplashScreen.
