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

1. You are designing a Windows Presentation Foundation (WPF) data entry application. The application uses data binding to bind controls in the user interface (UI) to business objects. The UI uses validation rules for each input control.
The data validation rules change based on the state of the business object.
You need to recommend a validation strategy that will allow changes to the validation rules without changes to the UI code.
What should you recommend?

A) Set the ValidationStep attribute on ValidationRule elements to CommittedValue.
B) Implement the IDataErrorInfo interface in the business objects and replace all ValidationRule elements with Exception ValidationRule elements.
C) Set the ValidationStep attribute on ValidationRule elements to RawProposedValue.
D) Implement the IDataErrorInfo interface in the business objects and replace all
ValidationRule elements with Data ErrorValidat ion Rule elements.

2. You are designing an n-tier solution that connects to a Microsoft SQL Server 2008 database.
You plan to deploy the database to development machines and to a staging database server from within Microsoft Visual Studio 2010. You plan to set up separate build configurations for development and staging. You also plan to deploy to multiple production database servers managed by an outside vendor.
You must not allow the outside vendor to access the Visual Studio projects.
You need to recommend an approach for configuring and deploying the production database servers.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

A) Use SQL Server 2008 Management Studio to deploy the production databases.
B) Use a Visual Basic SQL CLR Database Project.
C) Use a SQL Server 2008 Database Project.
D) Use VSDBCMD to deploy the production databases.

3. You are developing an application by using Microsoft .NET Framework 4.
The application will be used by all employees of your company. Local file stores on the computers are secure and inaccessible remotely.
You need to design a remote monitoring strategy to monitor the usage time of the application by each user.
What should you do?

A) Create a TraceLog object and the Trace object by using the System.Diagnostics element to trace startup, shutdown, and user idle time events throughout the application.
B) Create a TraceLog object by using the System.Diagnostics element in the application configuration file. Add the TraceSource element for startup, shutdown, and user idle time events.
C) Use the System.Management.Instrumentation namespace to issue event queries against methods that pass ProgressEvent and StoppedEvent arguments. Publish the events to the Event Log.
D) Use the System.Management.Instrumentation namespace to publish startup, shutdown, and user idle time events of the application. Publish the events to Microsoft Operations Manager.

4. You are designing an application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
You plan to design an instrumentation strategy for the application.
You need to ensure that the strategy meets the following requirements:
- Captures detailed performance information. - Enables or disables diagnostic messages by using an application configuration option without requiring the application to restart.
What should you design?

A) An override to the Debug class
B) A custom trace listener
C) A custom performance counter
D) An override to the EventLog class

5. 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) Event Tracing for Windows (ETW)
B) SQL Profiler
C) Application Center Test (ACT)
D) CLR Profiler
