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, Microsoft Visual Studio 2010, and Microsoft SQL Server 2008.
New features that require changes to be made to the database schema are added to the application every week.
You need to ensure that the changes made to the database schema do not require the application to be recompiled.
Which two actions should you perform? (Each correct answer presents part of the solution.
Choose two.)

A) Build a storage model and use it to access data from the business entities.
B) Build a conceptual model and use it to access data from the business entities.
C) Modify the xml mapping file when the schema changes occur.
D) Modify the conceptual schema xml file when the schema changes occur.

2. You are designing an n-tier Windows application by using Microsoft .NET Framework 4, Microsoft Visual Studio 2010, and Microsoft SQL Server 2008.
The application will replace an existing client/server application. The existing application was created by using Microsoft Visual Basic 6.0 and consists of a series of COM components that access a SQL Server database.
You plan to move the existing COM components into a Windows Communication Foundation (WCF) tier.
You need to ensure that the COM components can be replaced without impacting the existing user interface (UI) tier. You also need to ensure that the COM components can be replaced separately.
What should you do?

A) Create a common assembly on the UI tier of the new application to interface with the COM components.
B) Create a common assembly on the WCF tier of the new application to interface with the COM components.
C) Convert the Visual Basic 6.0 source code to managed code by using the Visual Studio converters. Use these code components on the client/server application until they are replaced individually with the new permanent managed code functionality.
D) Use .NET COM Interop on the client tier to interact directly with the COM components until they are replaced by the managed code.

3. You are debugging a Windows application that uses Windows Presentation Foundation (WPF) and Microsoft Visual Studio 2010.
The application is deployed as an XAML browser application (XBAP). Some users report that they are not able to use the drag-and-drop functionality.
You need to ensure that all users can use the drag-and-drop functionality.
What should you do?

A) Add the URL for the application to the browser's trusted sites list.
B) Require the FullTrust permission on the XBAP application.
C) Register the assembly that contains the IDataObject objects to the GAC on all client computers.
D) Use loose XAML.

4. 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 a DataSet object.
D) Use the DiffGram XML format.

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.
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.
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) Move the database update logic to a BackgroundWorker thread.
Ensure that the thread is enclosed in a TransactionScope Using block in the BackgroundWorkerDoWork method.
D) Use TransactionScope in a Using block on the UI thread.
Batch the database updates by setting the DbDataAdapter.UpdateBatchSize property to 2.
