Microsoft PRO: Design & Develop Wndws Apps Using MS .NET Framework 4 認定 070-518 試験問題:

1. You are designing a Windows Presentation Foundation (WPF) application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
During testing of the application, you identify several bottlenecks by using Windows Task Manager and Windows Performance Monitor.
You need to recommend a system test strategy that will meet the following requirements:
- Identify major application workloads.
- Identify the functions of the application that are most impacted.
Which testing strategy should you recommend?

A) Stability testing
B) Security testing
C) Usability testing
D) Scalability testing

2. You design a Windows Presentation Foundation (WPF) application that interacts with a Windows Communication Foundation (WCF) Web service. The WCF Web service throws exceptions of type Exception.
The WPF application crashes when the WCF Web service throws an exception.
You need to recommend an error-handling strategy that allows users to submit updated data to the WCF Web service without restarting the WPF application.
What should you recommend?

A) Modify the Web service to throw exceptions of type InvalidOperationException
B) Modify the Web service to throw custom exceptions derived from the ApplicationException class.
C) Modify the Web service to throw custom exceptions derived from the Exception class.
D) Modify the Web service to throw exceptions of type FaultExceptton.

3. You are developing an application by using Microsoft .NET Framework 4 and Microsoft
Visual Studio 2010.
The application contains a grid that displays customer data stored in a database table.
Users report that the grid takes a long time to display.
You plan to implement data caching to improve loading time for the grid.
You need to ensure that the cached data expires when the customer data is updated.
What should you do?

A) Use the System.WeB.Caching.CacheDependency class.
B) Use the System.Runtime.Caching.SqlChangeMonitor class.
C) Use the ADO.NET Entity Framework.
D) Use a static variable to store the Grid object.

4. You are designing an application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
The application is used mostly in a disconnected scenario. The application requires offline data from a Microsoft SQL Server 2008 database. When the application connects to the network, data will be modified and synchronized.
You need to ensure that the application does not access the database server directly to synchronize data when online.
Which technology should you use?

A) Remote Data Access
B) WCF Data Service
C) SQL Server Merge Replication
D) ADO.NET Sync Services

5. You are upgrading a stand-alone Windows Presentation Foundation (WPF) application and an XAML browser application (XBAP) to Microsoft .NET Framework 4.
You plan to add .NET 4 types and members to both applications.
Both applications consume a common utility assembly that modifies files on a local file system. The utility assembly requires full trust.
You need to ensure that both applications can use the common utility assembly without any security-related exceptions.
What should you do?

A) Change the <supportedRuntime> element for the XBAP application to the .NET Framework 3.5.
B) Apply the AllowPartiallyTrustedCallersAttribute attribute to the XBAP application.
C) Change the <supportedRuntime> element for the WPF application to the .NET Framework 3.5.
D) Apply the AllowPartiallyTrustedCallersAttribute attribute to the utility assembly.
