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?

You are designing a Windows client application by using Microsoft .NET Framework 4 and
Microsoft Visual Studio 2010. The application will read and write data that is stored in a
mainframe application. A hardware device that is located between the application and the
mainframe removes all XMLformatted messages. You need to ensure that the application
can request and receive data from the mainframe application. What should you create?

You have developed a Windows Forms server application by using Microsoft .NET
Framework 4. Client applications connect to the server application to receive streaming
media on demand on a single server. Each incoming connection is launched on a separate
thread. As the number of client applications increases, users report that connection
attempts intermittently fail. You need to ensure that users can connect to the server
application even when the number of client applications increases. What should you do?

You are designing a Windows Presentation Foundation (WPF) application by using
Microsoft .NET Framework 4 and Microsoft Visual Studio 2010. The application contains a
COM component. You plan to deploy the application to several client computers by using
read-only media. You need to ensure that the COM component is registered during
deployment of the application. Which deployment technology should you use?

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 packaging updates for multiple Windows Presentation Foundation (WPF)
applications by using Microsoft .NET Framework 4. Updates to the applications and to
third-party control files are available. Updates to the applications have dependencies upon
updates to the third-party control files. An update script is run at logon that allows only a
single command to be executed. You need to package the application updates and updates
to the third party controls to ensure that they are successfully installed. What should you
do?

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 developing a Windows Presentation Foundation (WPF) application by using
Microsoft .NET Framework 4 and Microsoft Visual Studio 2010. The application will run in a
partially trusted sandbox. You plan to deploy the application on client computers by using
the ClickOnce deployment technology. You plan to sign the deployment and application
manifest by using a trusted publisher certificate. You need to ensure that the following
requirements are met: • Users are not prompted for elevated permissions during application
deployment. • The application can request elevated permissions at runtime. Where should
you install the trusted publisher certificate?

You have developed a Windows application by using Microsoft .NET Framework 4,
Windows Presentation Foundation (WPF), and Microsoft SQL Server 2008. The application
is deployed as an XAML Browser Application (XBAP) and executes in the Internet Zone in
Internet Explorer. The application updates data in a SQL Server 2008 database. Users
report that a SecurityException exception occurs when the application attempts to save data
to the database. You need to design a solution to resolve the problem. What should you do?
