  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 publisher store on the deployment server

  D. in the trusted publisher store on each client computer

• Question 125:

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

• Question 126:

  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?

  A. Create a TraceLog object and the Trace object by using the System.Diagnostics element to trace startup, shutdown, and user idle time events throughout the application.
  B. Create a TraceLog object by using the System.Diagnostics element in the application configuration file. Add the TraceSource element for startup, shutdown, and user idle time events.
  C. Use the System.Management.Instrumentation namespace to publish startup, shutdown, and user idle time events of the application. Publish the events to Microsoft Operations Manager.
  D. Use the System.Management.Instrumentation namespace to issue event queries against methods that pass ProgressEvent and StoppedEvent arguments. Publish the events to the Event Log.
  C. Use the System.Management.Instrumentation namespace to publish startup, shutdown, and user idle time events of the application. Publish the events to Microsoft Operations Manager.

• Question 127:

  You are analyzing an application that uses Microsoft .NET Framework 4 and Microsoft SQL Server 2008.

  The application is used to maintain an inventory database and is accessed from several remote Windows client applications. The application frequently updates multiple rows in a database table by using a DbDotoAdopter object.

  Users report that the application runs slowly during peak business hours.

  When large numbers of records are changed by multiple users, you discover the following:

  The CPU utilization of the client applications is normal.

  The network utilization increases slightly.

  The CPU utilization of the database server remains close to the normal average for a day.

  You need to resolve the performance issue.

  What should you do?

  A. Disable batch updates. Modify the client application to perform a single update.
  B. Insert a random time interval between updates.
  C. Move the update method calls to a separate BackgroundWorker thread.
  D. Remove any limit on batch update sizes. Modify the client application to perform a single update.
  D. Remove any limit on batch update sizes. Modify the client application to perform a single update.

• Question 128:

  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?

  A. Denormalize the data to fewer tables.
  B. Create stored procedures to abstract the tables.
  C. Use System.Runtime.Caching to cache query results on the client.
  D. Create a separate data layer with caching.
  D. Create a separate data layer with caching.

• Question 129:

  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.

  What should you do?

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

  You need to recommend an approach for meeting the requirements.

  What should you recommend?

  A. Move the initialization code to the code-behind of the main window.
  B. Launch a custom splash screen by using a Window object. When the initialization completes, launch the main window from the splash screen.
  C. Create a SplashScreen object. Display the object in the code-behind of the App.xaml file.
