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

Question 1

You are analyzing an application that uses Microsoft .NET Framework 4 and Microsoft SQL Server 2008.
The application is used to maintain an inventory database and is accessed from several remote Windows client applications. The application frequently updates multiple rows in a database table by using a DbDataAdapter object.
Users report that the application runs slowly during peak business hours.
When large number of records are changed by multiple users, you discover the following:
The CPU utilization of the client applications is normal.
The network utilization increases slightly.
The CPU utilization of the database server remains close to the normal average
for a day.
You need to resolve the performance issue.
What should you do?

A. Disable batch updates. Modify the client application to perform a single update.
B. Remove any limit on batch update sizes. Modify the client application to perform a single update.
C. Move the update method calls to a separate BackgroundWorker thread.
D. Insert a random time interval between updates.

Question 2

You are designing a Windows application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
You plan to implement control caching to improve the loading time of a control. It is not required to refresh the content of the control after the application loads.
The application will be compiled by using the .NET 4 client profile.
You need to ensure that the following requirements are met:
--
The control is reusable in multiple forms.
Data in the control is cached when the application is loaded.
What should you do?

A. In the Load event of the application window, add code to load the control. Save the control to the cache by using objects in the System.WeB.Caching namespace.
B. In the Load event of the application window, add code to load the control. Save the control to an instance variable.
C. In the constructor of the application window, add code to load the control. Save the control to the cache by using objects in the System.WeCaching namespace.
D. In the constructor of the application window, add code to load the control. Save the control to a static variable.

Question 3

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.
The mainframe-based database will be replaced in one year.
You have the following requirements:
---
Centrally manage all database connections.
Minimize changes to the code base when the database is replaced.
Ensure that the WPF application will not need to be redeployed when the database
is replaced.
You need to recommend an approach for designing the data access layer.
What should you recommend?

A. 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.
B. 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.
C. 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.
D. 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.

Question 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 the Thread.Abort() statement to terminate the worker thread. Start a new BackgroundWorker thread from the main UI thread.
B. Use the DoWork handler of the worker thread and test a shared status value.
Use a break statement to terminate the Parallel.ForEach loop.
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 loopStatus.Stop() statement to terminate the Parallel.ForEach loop.

Question 5

You are designing a Windows Presentation Foundation (WPF) application.
The WPF application must run against either Microsoft SQL Server 2008 or a third-party
database system without duplicating data access logiC.
You need to recommend a data access technology.
What should you recommend?

A. ADO.NET using DataSet objects and SqIDataAdapter objects
B. ADO.NET using DataSet objects and SqlDataReader objects
C. LINQ to SQL
D. LINQ to Entities
