You are developing a Windows application. The application will process data that is stored
on the user’s computer. You plan to design a data storage strategy. You need to ensure that
the following requirements are met: • Local data can be accessed only by the application •
Local data can be encrypted and compressed • Local data can be shared between multiple
users by sending them the data file by email • Users must be able to open the data file
directly from the email message Which local data storage technology should you use?

You are designing an application by using Windows Presentation Foundation (WPF) and
Microsoft NET Framework 4. The user interface (UI) tier of the application will be
implemented by using WPF. The middle tier of the application will be implemented by using
Windows Communication Foundation (WCF). The middle tier will contain several methods
that update data in a remote database. The middle tier will also contain a long-running
method named Process Data. The Process Data method performs database operations and
can take several minutes to complete. You need to ensure that the UI of the application can
continue to call other methods while the Process Data method is running What should you
do?

You are developing an application by using Windows Forms and Microsoft NET Framework
4. The user interface (UI) of the application can be resized. You need to ensure that the
images in the application scale to the entire height and width of the UI without degradation.

What should you do?

You are designing an application by using Microsoft NET Framework 4 and Microsoft Visual
Studio 2010. Your development team consists of designers and C# developers. • You need
to ensure that the application meets the following requirements: • Kit allows separation of
user interface (UI) code and business logic. • “It allows the UI to be data-bound without
requiring a code-behind file. Which technology should you use?

You are designing a Windows client 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 write the following code segment in
the middle tier: <ServiceContractO> — Public Interface lWcf Service <OperationContractO>
— <FaultContract(GetType(ApplicationException))> — Sub ProcessData(ByVal d As Data)
End Interface The Process Data service method is a long-running operation. You need to
ensure that the application meets the following requirements: “Users can continue to use
the user interface while the Process Data service method is running. “Message delivery is
reliable. What should you use?

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?

You are designing a .NET Framework 4 solution that contains a Windows Presentation
Foundation (WPF) application. The WPF application includes CPU-intensive calculations.
The calculations can be run on a separate process and can effectively be isolated from the
rest of the WPF application. You need to recommend a deployment strategy that maximizes
the scalability of the calculations for each user. What should you recommend?

You are designing a Windows Presentation Foundation (WPF) application that accesses a
business tier. The business tier is implemented as a Windows Communication Foundation
(WCF) service and stores data in a Microsoft SQL Server 2008 database. The WCF service
will be accessed by external applications that do not use the .NET Framework. You need to
recommend an approach for passing data between layers. What should you recommend?

You are designing a Windows Presentation Foundation (WPF) application that uses .NET
Framework 4. The WPF application will be deployed to 5,000 users worldwide. You need to
recommend an approach for identifying problems that users will experience. Which testing
methodology should you recommend?

You are designing a .NET Framework 4 solution that includes a Windows Presentation
Foundation (WPF) application. The WPF application connects to a Microsoft SQL Server
2008 database. You plan to deploy the WPF application to millions of client computers. The
SQL Server database will be hosted in a data center. The WPF application will query the
database to provide type-ahead assistance as users enter data. The WPF application will
send a query after each character is entered. Each query will access multiple joined tables.
You need to recommend an approach for maximizing scalability of the solution. What should
you recommend?
