You are designing a Windows Presentation Foundation (WPF) application that displays thumbnail images of photographs. The thumbnails are arranged in rows and columns.

The number of columns must automatically update based on the size of the application window.

You need to recommend a container for displaying all the thumbnail images at the same size.

Which container should you recommend?

You are designing a Windows Presentation Foundation (WPF) application. Business entity objects are bound to controls on each data entry window.

The WPF application must meet the following requirements:
Display a watermark in each empty text box.
Display watermarks in a lighter color than user entries.

The watermark code must be reusable with other user interface controls. You need to recommend an approach for creating the watermarks.

What should you recommend?

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?

You are designing a Windows application.

The application must meet the following requirements:
Provide three-dimensional views of data.
Display images, text, graphs, and videos.
Support porting to a browser-based application.

You need to recommend a technology that meets the requirements.

Which technology should you recommend?

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.)

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

You need to use a replacement culture for the application at runtime. You also need to ensure that the information in the custom culture will be available to the application.

Which two tasks should you perform? (Each correct answer presents part of the solution. Choose two.)

You are designing an n-tier solution that includes a Windows Presentation Foundation (WPF) client application. The WPF application connects to a middle-tier server that runs the data access layer. The data access layer connects to a Microsoft SQL Server 2008 database and to a mainframe-based database.

The mainframe-based database will be replaced in one year.

You have the following requirements:
Centrally manage all database connections.
Minimize changes to the code base when the database is replaced. Ensure that the WPF application will not need to be redeployed when the database is replaced.

You need to recommend an approach for designing the data access layer.

What should you recommend?

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.)

You are designing a Windows Presentation Foundation (WPF) application.

The application calls methods that perform long-running computational tasks.

You need to recommend an approach for ensuring that the application remains responsive while the tasks are executing.

What are two possible ways to achieve this goal? (Each correct answer presents a complete solution.
Choose two.)

You are designing an application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010. The application will store data that includes a time and date stamp.

The middle tier of the application is implemented by using Windows Communication Foundation (WCF). The middle tier connects to geographically separated database servers.

You need to ensure that the application meets the following requirements:
Data stored contains time and date information local to the database server.
Data stored contains Universal Coordinated Time (UTC).

Which class should you use?
