1. You are designing a Windows application by using Microsoft .NET Framework 4.
Remote users have limited network connectivity. Users will not have write permissions to
the local file system.
You plan to design the error logging strategy for the application.
You need to ensure that the application can collect error information. You also need to
ensure that the errors can be analyzed from a centralized location. What should you do?

A) Use a local log file.
B) Log the errors to the Windows System event log.
C) Use the Microsoft Sync Framework.
D) Log the errors to a Web service.

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

3. You are evaluating an existing Windows Presentation Foundation (WPF) application. The WPF application runs in a Web browser as a XAML browser application (XBAP). The WPF application runs in the Intranet zone with Full Trust. A client certificate for the WPF application has been generated.
Users are unable to access the WPF application. You locate the following message in the security log: "User has refused to grant required permissions to the application." Users state that they are clicking OK in all message boxes that appear.
You need to recommend an approach for ensuring that the WPF application runs correctly on all client computers.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

A) Use the Code Access Security Policy Tool to grant the appropriate permissions.
B) Import the client certificate to the Trusted Root store.
C) Modify the ClickOnce manifest for the WPF application to grant the appropriate permissions.
D) Sign the ClickOnce manifest for the WPF application.

4. ---
You are analyzing a Windows client application that uses Microsoft Visual Studio 2010 and Microsoft SQL Server 2008.
The application updates two database tables from the main user interface (UI) thread.
You need to ensure that the following requirements are met:
The database tables are either updated simultaneously or not updated at all.
Users are notified of the success or failure of the updates.
Users are able to perform other tasks during the update process.
What should you do?

A) Use TransactionScope in a Using block on the main thread.
Create a BackgroundWorker thread within the block.
Move the database updates to the BackgroundWorkerDoWork method.
B) Use TransactionScope in a Using block on the UI thread.
Create a DependentTransaction object within the block and pass the object to the BackgroundWorkerReportProgress method.
Use the object in the ReportProgress method to create a new TransactionScope block.
C) Use TransactionScope in a Using block on the UI thread.
Batch the database updates by setting the DbDataAdapter.UpdateBatchSize property to 2.
D) Move the database update logic to a BackgroundWorker thread.
Ensure that the thread is enclosed in a TransactionScope Using block in the BackgroundWorkerDoWork method.

5. You are designing a Windows Presentation Foundation (WPF) application.
The WPF application must run against either Microsoft SQL Server 2008 or a third-party
database system without duplicating data access logiC.
