You are designing a Windows Presentation Foundation (WPF) application by using
Microsoft .NET Framework 4 and Microsoft Visual Studio 2010. During testing of the
application, you identify several bottlenecks by using Windows Task Manager and Windows
Performance Monitor. You need to recommend a system test strategy that will meet the
following requirements: • Identify major application workloads. • Identify the functions of the
application that are most impacted. Which testing strategy should you recommend?

You are designing a Windows Presentation Foundation (WPF) application by using
Microsoft .NET Framework 4 and Microsoft Visual Studio 2010. The application will consist
of a user interface (UI) tier and a middle tier. The middle tier will be implemented by using
Windows Communication Foundation (WCF). You plan to design the exception handling
strategy for the application. Each method in the middle tier will contain the following catch
block. Catch e As ArgumentNullException Throw e When testing the application, you
discover that all ArgumentNullExceptions that occur in the middle tier do not contain
accurate stack trace information. What should you do?

You are developing an application by using Microsoft .NET Framework 4. The application
will be used by all employees of your company. Local file stores on the computers are
secure and inaccessible remotely. You need to design a remote monitoring strategy to
monitor the usage time of the application by each user. What should you do?

You are designing a Windows Presentation Foundation (WPF) application by using
Microsoft .NET Framework 4 and Microsoft Visual Studio 2010. You need to ensure that the
following requirements are met: • All UI elements are labeled, • All property values are
exposed. • Keyboard navigation contains tab stops for all controls. • The application
functions on high contrast displays. Which testing strategy should you recommend?

You are designing a Windows Presentation Foundation (WPF) application by using
Microsoft .NET Framework 4 and Microsoft SQL Server 2008. The application runs
successfully on a local client computer by using your user account. You deploy the
database of the application to the production server. You configure the application
connection string to use the Windows Authentication mode. You deploy the application to
several client computers that use other applications on the network. The client computers
access different databases on the production server by using the Windows Authentication
mode. Users report that the application is not working and that they receive a database
connection exception. You need to identify the source of the problem. What is the source of
the problem?

You are deploying an application on Windows client computers by using Microsoft .NET
Framework 4 and Microsoft Visual Studio 2010. You need to ensure that the deployment
package meets the following requirements: • Grants only the necessary permissions • Adds

a shortcut to the Windows Start menu • Registers the application within Programs and
Features • Can be published to a Web site Which deployment strategy should you use?

You are creating a Windows Presentation Foundation (WPF) application by using Microsoft
.NET Framework 4. You need to ensure that when the user attempts to run the application,
the user cannot use the application if a new version of the application is available. What
should you do?

You are designing an update to an existing Windows Presentation Foundation (WPF)
application. Users can purchase and download photographs from the company’s Web
server by using the WPF application. Photographs must be viewable only when logged in as
the user who purchased the photographs. You need to recommend a download location for
the photographs. Which location should you recommend?

You are designing an n-tier solution that connects to a Microsoft SQL Server 2008
database. You plan to deploy the database to development machines and to a staging
database server from within Microsoft Visual Studio 2010. You plan to set up separate build
configurations for development and staging. You also plan to deploy to multiple production
database servers managed by an outside vendor. You must not allow the outside vendor to
access the visual Studio projects. You need to recommend an approach for configuring and
deploying the production database servers. Which two actions should you recommend?
(Each correct answer presents part of the solution. Choose two.)

You are designing a .NET Framework 4 solution that contains a Windows Presentation
Foundation (WPF) application and a Windows Communication Framework (WCF) Web
service. The WPF application will be deployed to users’ desktops located in the company’s
corporate network. The WCF Web service will be deployed to a Web farm located in the
company’s perimeter network. The firewall between the perimeter network and the Internet
allows only HTTP and HTTPS traffic. You need to recommend an approach for minimizing

the attack surface of the WCF Web service. What should you recommend?
