Microsoft 70-518 Online Questions & Answers

• Question 231:

  You are designing an application by using Windows Presentation Foundation (WPF) and Microsoft .NET Framework 4.

  The application consists of multiple data entry screens.

  You need to ensure that users can return to previous screens. You also need to ensure that users can view a history of screens.

  What should you do?

  A. Create buttons to allow a user to open a new window for the data entry screens.
  B. Create buttons to allow a user to open a new Window as an MDI child window for the data entry screens.
  C. Create hyperlinks to allow a user to move between data entry screens. Use the NavigationService class to manage navigation history.
  D. Create hyperlinks to allow a user to move between data entry screens. Use the NavigationProgressEventArgs class to manage navigation history.
  C. Create hyperlinks to allow a user to move between data entry screens. Use the NavigationService class to manage navigation history.

• Question 232:

  You are designing a Windows Presentation Foundation (WPF) application that accesses a business tier. The business tier is implemented as a Windows Communication Foundation (WCF) service and stores data in a Microsoft SQL Server

  2008 database.

  The WCF service will be accessed by external applications that do not use the .NET Framework. You need to recommend an approach for passing data between layers.

  What should you recommend?

  A. Use custom .NET classes with XML serialization.
  B. Use custom .NET classes with binary serialization.
  C. Use the DiffGram XML format.
  D. Use a DataSet object.
  A. Use custom .NET classes with XML serialization.

• Question 233:

  You are designing an n-tier solution that includes a Windows Presentation Foundation (WPF) client application. The WPF application connects to a middle-tier server that runs the data access layer. The data access layer connects to a

  Microsoft SQL Server 2008 database and to a mainframe-based database.

  The mainframe-based database will be replaced in one year.

  You have the following requirements:

  Centrally manage all database connections.

  Minimize changes to the code base when the database is replaced.

  Ensure that the WPF application will not need to be redeployed when the database is replaced.

  You need to recommend an approach for designing the data access layer.

  What should you recommend?

  A. Create a data access layer class that uses a database factory class to access all databases. Add the connection string information for the databases to the configuration file for the WPF application.
  B. Add the connection string information for the databases to the configuration file for the WPF application. Implement one class in the WPF application for each data source.
  C. Create a data access layer class that uses a database factory class to access all databases. Add the connection string information for the databases to the configuration file for the data access layer class.
  D. Add the connection string information for the databases to the configuration file for the WPF application. Implement a database factory class from within the WPF application.
  C. Create a data access layer class that uses a database factory class to access all databases. Add the connection string information for the databases to the configuration file for the data access layer class.

• Question 234:

  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 SqlDataAdapter objects
  B. LINQ to Entities
  C. LINQ to SQL D. ADO.NET using DataSet objects and SqlDataReader objects
  B. LINQ to Entities

• Question 235:

  You are designing an n-tier .NET Framework 4 solution that includes a Windows Presentation Foundation (WPF) application. You need to recommend an approach for ensuring that the solution can support 5,000 concurrent users.

  What should you recommend?

  A. Buffer overflow testing
  B. Integration testing
  C. Component stress testing
  D. Stress testing
  A. Buffer overflow testing

• Question 236:

  You are designing a .NET Framework 4 solution. The solution contains a Windows Presentation Foundation (WPF) application and a Windows Communication Foundation (WCF) Web service. The WPF application uses the WCF Web

  service to store data in a Microsoft SQL Server 2008 database.

  You have the following requirements:

  Ensure that the WPF application functions while users' computers are offline.

  Minimize the time spent sending data to the WCF Web service.

  Minimize disk space requirements for data storage.

  You need to recommend an approach for synchronizing data between the WPF application and the database.

  Which two actions should you recommend? (Each correct answer presents part of the solution.Choose two.)

  A. Store data in custom business objects. Serialize data locally by using custom serialization.
  B. Create a local caching solution that periodically checks for Internet connectivity, uses local memory, and batches changes to the WCF Web service.
  C. Create a local caching solution that periodically checks for Internet connectivity and writes directly to the local data store and to the WCF Web service.
  D. Store data in DataSet objects. Serialize data locally by using XML serialization.
  A. Store data in custom business objects. Serialize data locally by using custom serialization.
  C. Create a local caching solution that periodically checks for Internet connectivity and writes directly to the local data store and to the WCF Web service.

• Question 237:

  You are reviewing multiple Windows Presentation Foundation (WPF) applications that capture postal addresses. The WPF applications have different appearances and functionality. Each WPF application uses a different control to visualize

  the captured addresses.

  You plan to modify all WPF applications to allow developers to visualize addresses by using a common template.

  You need to recommend an approach for standardizing the visualization of captured addresses.

  What should you recommend?

  A. Use a ControlTemplate object.
  B. Use a FrameworkTemplate object.
  C. Use a Data Template object.
  D. Use an ItemsPanelTemplate object.
  C. Use a Data Template object.

• Question 238:

  Developers required to use part of functionality of COM assembly. You must to design an interop assembly that expose COM functionality. Choose 2 as part.

  A. Design assembly that expose required functionality of COM
  B. Design assembly that expose full functionality of COM
  C. Use embedded referencing
  D. Use normal referencing
  A. Design assembly that expose required functionality of COM
  D. Use normal referencing

• Question 239:

  You are designing a sales and inventory tracking system by using Microsoft Visual Studio 2010 and Microsoft SQL Server 2008. The sales, inventory, and shipping tables will reside in different databases on different database servers.

  You need to ensure that the tables are updated simultaneously.

  What should you do?

  A. Use LINQ to SQL.
  B. Use Distributed transactions.
  C. Use Microsoft Sync Framework.
  D. Use the ADO.NET Entity Framework.
  B. Use Distributed transactions.
