Microsoft 070-518 Value Pack (Frequently Bought Together)

You are designing a Windows Presentation Foundation (WPF) application. The WPF application displays indicators to compare your company's past performance to the current day's operations datA.
The WPF application accesses historic data from your company's data warehouse through a Web service, and accesses current data directly from a Microsoft SQL Server 2008 database.
The WPF application must meet the following requirements:
- Retrieve historic data from the data warehouse at application startup and then
once per day.
- Retrieve current data from the database every five minutes, and then update the
indicators.
- Cache all retrieveddata.
- Target the .NET Framework 4 Client Profile.
You need to recommend an approach to data caching.
What should you recommend?

• A. UseSystem.Web.Caching with an absolute expiration.
• B. UseSystem.Web.Caching with a sliding expiration.
• C. Use System.Runtime.Caching with a sliding expiration.
• D. Use System.Runtime.Caching with an absolute expiration.

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. 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.
• B. Create a global WIN 32 unhandled exception filter.
  Record relevant application-specific information to an external log from within the filter.
• C. Subscribe to the unhandled exception event handler for the AppDomain object.
  Record relevant application-specific information to an external log.
• 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 developing a Windows application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
The application will consume a Windows Communication Foundation (WCF) service. The WCF service will provide data to the application. You plan to use the ADO.NET Entity Framework to create a data model that will be used by the application.
Another development team makes changes to the WCF service data contract.
You need to ensure that changes made to the WCF service data contract do not require the application to be recompiled.
What should you do?

• A. Create a storage model based on the business model. Use a class generated from the storage model for programming,
• B. Create a conceptual model and a storage model based on the existing version of the WCF service.
• C. Create a storage model based on the schema of the existing WCF service. Update the mapping file when the new version of the WCF service is available.
• D. Create a conceptual model based on the business model. Use a class generated from the conceptual model for programming. Update the mapping file when the new version of the WCF service is available.

You are designing a Windows Presentation Foundation (WPF) application.
The application data files have the file name extension .abC.
The WPF application installer must meet the following requirements: - Add a shortcut to the desktop. - Install infrequently used assemblies on demand.
--
Associate the .abc file name extension with the WPF application. Roll back the installation in the event of a failure.
You need to recommend a deployment method.
What should you recommend?

• A. Background Intelligent Transfer Service (BITS)
• B. ClickOnce
• C. XCopy
• D. Windows Installer

You are designing a Windows Presentation Foundation (WPF) application that will be used to display real-time data from a Microsoft SQL Server 2008 database.
You need to recommend an approach for displaying the datA.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

• A. Use a SqlCacheDependency object in the data layer to query the database when a change is detected.
• B. Implement OneWayToSource binding between the controls in the WPF application and objects in the data layer.
• C. Implement OneWay binding between the controls in the WPF application and objects in the data layer.
• D. Use a System.Runtime.Caching object in the data layer with a sliding expiration, and query the database when the Cache object expires.
