Microsoft PRO: Design & Develop Wndws Apps Using MS .NET Framework 4 Sample Questions:

1. 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 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.
D) 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.

2. You are designing a .NET Framework 4 solution that contains a Windows Presentation Foundation (WPF) application and a Windows Communication Framework (WCF) Web service.
The WPF application will be deployed to users1 desktops located in the company's corporate network. The WCF Web service will be deployed to a Web farm located in the company's perimeter network. The firewall between the perimeter network and the Internet allows only HTTP and HTTPS traffiC.
You need to recommend an approach for minimizing the attack surface of the WCF Web service.
What should you recommend?

A) Set up an SSL certificate on the server.
B) Configure a WCF endpoint to use the basicHttpBinding binding.
C) Add a load-balancing router to the Web farm configuration.
D) Configure a WCF endpoint to use the NetTcpBinding binding.

3. You are designing a Windows Forms application. The application connects to a Microsoft SQL Server 2008 database.
You need to recommend an approach for retrieving and logging all informational messages and error messages reported by the database.
What should you recommend?

A) Retrieve informational messages in a SqlException object. Retrieve error messages by creating a handler for the InfoMessage event.
B) Retrieve informational messages and error messages in a SqlException object.
C) Retrieve informational messages and error messages by creating a handler for the InfoMessage event.
D) Retrieve informational messages by creating a handler for the InfoMessage event. Retrieve error messages in a SqlException object.

4. You are designing an application by using Windows Presentation Foundation (WPF) and
Microsoft .NET Framework 4.
The user interface (UI) tier of the application will be implemented in WPF.
The middle tier of the application is implemented by using an existing COM component.
The middle tier contains a long-running method named ProcessDatA.
You need to ensure that users can continue to use the UI while ProcessData is running.
What should you do?

A) Call the DoEvents method of the Application class before invoking ProcessDat
B) Call the Run method of the Dispatcher class before invoking ProcessDatA.
C) Use the Invoke method of the Dispatcher class to call ProcessDatA.
D) Use an asynchronous worker thread to call ProcessDatA.

5. 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.
Batch the database updates by setting the DbDataAdapter.UpdateBatchSize property to 2.
B) 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.
C) 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.
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
