You design a Windows Presentation Foundation (WPF) application that interacts with a Windows Communication Foundation (WCF) Web service. The WCF Web service throws exceptions of type Exception.
The WPF application crashes when the WCF Web service throws an exception.
You need to recommend an error-handling strategy that allows users to submit updated data to the WCF Web service without restarting the WPF application.
What should you recommend?

• A. Modify the Web service to throw exceptions of type InvalidOperationException
• B. Modify the Web service to throw exceptions of type FaultExceptton.
• C. Modify the Web service to throw custom exceptions derived from the ApplicationException class.
• D. Modify the Web service to throw custom exceptions derived from the Exception class.

You design a Windows Presentation Foundation (WPF) application that connects to a Microsoft SQL Server 2008 database.
The WPF application becomes unresponsive at times. When the WPF application is running, physical memory usage is between 90 percent and 95 percent.
You need to recommend a tool that will identify the memory usage characteristics of the WPF application.
Which tool should you recommend?

• A. SQL Profiler
• B. Event Tracing for Windows (ETW)
• C. CLR Profiler
• D. Application Center Test (ACT)

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).
Each method in the middle tier will contain the following catch block.
Catch(ArgumentNullExceptione)
{
throw e;
}
When testing the application, you discover that all ArgumentNullExceptions exceptions that occur in the middle tier do not contain accurate stack trace information.
You need to design the exception handling strategy for the application.
What should you do?

• A. Remove the exception parameter from the ArgumentNullException handler.
• B. Use a DispatcherUnhandledExceptionEvent handler in the UI tier.
• C. Create an ArgumentNullException handler in the UI tier.
• D. Use a DispatcherUnhandledExceptionEvent handler in the middle tier.

You are designing a .NET Framework 4 solution that includes a Windows Presentation Foundation (WPF) application, a Windows service, and a private assembly shared by the WPF application and by the Windows service.
The solution stores data in a local Microsoft SQL Server Compact 3.5 database. The WPF application and Windows service will each access the database directly. The solution will be installed by using Windows Installer.
You have the following requirements:
- The installer must allow users to specify the installation folders for the WPF application and for the database. - The solution must support the deployment of updates to the WPF application without restarting the Windows service.
You need to recommend an approach for installing the solution.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

• A. Install the Windows service to a different folder from the WPF application.
• B. Install the Windows service to the same folder as the WPF application.
• C. In the installer, create a registry key that stores the WPF application installation path.
• D. In the installer, set an environment variable that defines the database installation path.

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?

• A. In the trusted root store on the deployment server
• B. In the trusted root store on each client computer
• C. In the trusted publisher store on the deployment server
• D. In the trusted publisher store on each client computer
