Microsoft PRO: Design & Develop Wndws Apps Using MS .NET Framework 4 Sample Questions:
1. You design a Windows Presentation Foundation (WPF) application that connects to a Microsoft SQL Server 2008 database.
The WPF application becomes unresponsive at times. When the WPF application is running, physical memory usage is between 90 percent and 95 percent.
You need to recommend a tool that will identify the memory usage characteristics of the WPF application.
Which tool should you recommend?
A) SQL Profiler
B) CLR Profiler
C) Application Center Test (ACT)
D) Event Tracing for Windows (ETW)
2. You are designing a Windows Presentation Foundation (WPF) application that uses .NET Framework 4. The application uses a subset of the functionality provided by a third-party COM component that will be replaced later.
The application developers must have access to only the required subset of functionality.
You need to recommend a solution that meets the requirements.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)
A) Create an adapter assembly that exposes the required subset of the COM component functionality.
B) In the adapter assembly, use an embedded interop reference.
C) Create an adapter assembly that exposes the entire functionality of the COM component.
D) In the adapter assembly, use a standard interop reference.
3. An existing Windows application uses a Windows Communication Foundation (WCF) Web service that is available only to employees.
You have the following requirements:
---
Make the WCF Web service available to business partners.
Enable business partners to send a profile token.
Ensure that the currently deployed application continues to function.
You need to recommend a solution that meets the requirements.
What should you recommend?
A) Use SOAP headers to pass the profile token to the service operations.
B) Modify the WCF Web service operations to accept the profile token as an additional parameter.
C) Implement the WCF Web service as a REST service.
D) Convert the WCF Web service to a Duplex service that implements a callback to accept the profile token.
4. You are updating a Windows desktop client application that was created by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
The application displays data derived from several database queries. The display takes a long time to update.
The application currently uses a BackgroundWorker thread and a Parallel.ForEach statement on that thread.
Users have requested a modification to the program that would allow them to interrupt the display of data and begin processing a new and different query.
You decide to provide a new Stop button on the user interface (UI) to allow the user to terminate the current data display and initiate the new query. The main UI thread must be notified when the current data processing is terminated so that the new query can be started.
You need to implement the Stop button event handler.
What should you do?
A) Use the DoWork handler of the worker thread and test a shared status value.
Use a loopStatus.Stop() statement to terminate the Parallel.ForEach loop.
B) Use the DoWork handler of the worker thread and test a shared status value.
Use the Thread.Abort () statement to terminate the worker thread.
Start a new BackgroundWorker thread from the main UI thread.
C) Use a CancelAsync() function to cancel the worker thread.
In the Parallel.ForEach loop, test the CancellationPending property.
If the property is set to true, perform the following tasks:
Write a loopStatus.Stop() statement.
Set the DoWorkEventArgs.Cancel property to true.
Use a return statement to exit from the loop.
D) Use the DoWork handler of the worker thread and test a shared status value.
Use a break statement to terminate the Parallel.ForEach loop.
5. ---
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) Create a local caching solution that periodically checks for Internet connectivity, uses local memory, and batches changes to the WCF Web service.
B) 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.
D) Store data in DataSet objects. Serialize data locally by using XML serialization.
