Microsoft PRO: Design & Develop Wndws Apps Using MS .NET Framework 4 070-518 Prüfungsfragen mit Lösungen

Frage #1

---
You are designing updates to a Windows solution that processes complex scientific datA.The solution extracts analyzed data from Microsoft Excel by using an application-level add-in.
You have the following requirements:
Deploy the Excel add-in to client machines with the application.
Ensure that the solution supports Excel 2007 and Excel 2010.
Minimize the size of the deployment package.
You need to recommend an approach that meets the requirements.
What should you recommend?

A. Embed the Excel 2010 COM library.
B. Include the primary interop assembly for Excel 2007.
C. Embed the type information from the Excel 2010 COM library.
D. Include the primary interop assembly for Excel 2010.

Frage #2

You are designing an application by using Windows Presentation Foundation (WPF) and Microsoft .NET Framework 4.
The application retrieves customer data from an enterprise resource planning (ERP) system.
You need to ensure that the following requirements are met:
---
Customer data is retrieved only once.
Customer data is available on multiple forms within the application.
Forms can implement Two-Way binding to the customer datA.
What should you do?

A. Store the results of the query in a static Data Table object that is used by all the forms.
B. Design a static class for the data that implements the INotifyPropertyChanged interface. Raise the PropertyChanged event to notify the forms when data is changed.
C. Store the results of the query in a local XML file. Bind all forms to an XMLDataAdapter object that references the local XML file.
D. Design a static class for the data that implements the IObservable interface. Subscribe to the static class from each of the forms that use the datA.

Frage #3

You are designing a .NET Framework 4 solution that contains a Windows Presentation Foundation (WPF) application. The WPF application includes CPU-intensive calculations.
The calculations can be run on a separate process and can effectively be isolated from the rest of the WPF application.
You need to recommend a deployment strategy that maximizes the scalability of the calculations for each user.
What should you recommend?

A. Deploy the calculation logic as a Windows Communication Foundation (WCF) service to servers. Deploy the WPF application to the same servers.
B. Deploy the calculation logic as a separate assembly along with the WPF application to each client computer. Invoke methods in the assembly synchronously.
C. Deploy the calculation logic as a separate assembly along with the WPF application to each client computer. Invoke methods in the assembly asynchronously.
D. Deploy the calculation logic as a Windows Communication Foundation (WCF) service to servers. Deploy the WPF application to each client computer.

Frage #4

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.

A. 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.
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 WPF application.
D. 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.

Frage #5

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