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.
You need to recommend a data access technology.
What should you recommend?

• A.ADO.NET using DataSet objects and SqIDataAdapter objects
• B.ADO.NET using DataSet objects and SqlDataReader objects
• C.LINQ to SQL
• D.LINQ to Entities

You are designing a complex and critical Windows desktop application by using Microsoft
.NET Framework 4 and Microsoft Visual Studio 2010.
You plan to implement a logging strategy for the application.
You need to record all unexpected errors that occur in the application.
What should you do?

• A.Subscribe to the unhandled exception event handler for the AppDomain object.
  Record relevant application-specific information to an external log.
• B.Create a generic catch (Exception e) block in the Main method of the application.
  Record relevant application-specific information to a log in the Main method.
• C.Create a global WIN 32 unhandled exception filter.
  Record relevant application-specific information to an external log from within the filter.
• D.Subscribe to the unhandled exception event handler for the application's dispatcher on the main application thread.
  Record relevant application-specific information to an external log.

You are designing a Windows Presentation Foundation (WPF) application.
The application will be localized into multiple languages.
You need to recommend an approach for preparing the application for localization.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

• A.Translate the contents of the appropriate XAML elements into each localization language.
• B.Add an application setting for each language to the App.config file.
• C.Define aUICulture element for each language in the project file.
• D.Add UID attributes to language-specific elements in the XAML file.

You are designing an n-tier Windows application by using Microsoft .NET Framework 4, Microsoft Visual Studio 2010, and Microsoft SQL Server 2008.
The application will replace an existing client/server application. The existing application was created by using Microsoft Visual Basic 6.0 and consists of a series of COM components that access a SQL Server database.
You plan to move the existing COM components into a Windows Communication Foundation (WCF) tier.
You need to ensure that the COM components can be replaced without impacting the existing user interface (UI) tier.
You also need to ensure that the COM components can be replaced separately.
What should you do?

• A.Use .NET COM Interop on the client tier to interact directly with the COM components until they are replaced by the managed code.
• B.Convert the Visual Basic 6.0 source code to managed code by using the Visual Studio converters. Use these code components on the client/server application until they are replaced individually with the new permanent managed code functionality.
• C.Create a common assembly on the UI tier of the new application to interface with the COM components.
• D.Create a common assembly on the WCF tier of the new application to interface with the COM components.

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 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.
• B.Use TransactionScope in a using block on the UI thread.
  Batch the database updates by setting the DbDataAdapter.UpdateBatchSize property to 2.
• C.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.
• 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
