You need to ensure that the user interface (UI) of the application dynamically changes the application theme based on the ambient luminosity.
What should you use?

A) A VisualBrush control to paint the UI
B) A visual state manager to add VisualStateGroup objects
C) A RenderTransform control applied to the root canvas
D) An attached behavior to change a merged resource dictionary

2. You are designing an application by using Microsoft .NET Framework 4, Microsoft Visual Studio 2010, and Microsoft SQL Server 2008.
The application will be used by a sales team to enter sales orders and update customer information.
You need to ensure that the application meets the following requirements:
- Allows users to enter sales orders while their computers are disconnected from the

3. You are designing a Windows Presentation Foundation (WPF) application that connects to a data access layer on a server.
You have the following requirements for all security-related exceptions:
- Exceptions that occur in the data access layer must be handled in a single exception handler in the WPF application. - Exceptions must pass customized messages back to the WPF application.
You need to recommend an approach for creating new exception classes in the data access layer.
From which class should you inherit?

A) System.InvalidOperationException
B) System.ApplicationException

You have the following requirements:
Collect information about all errors associated with the application.
Store and view all error information in a centralized location.
Minimize the network bandwidth required for the transfer of error information.
You need to recommend a strategy for reporting error information.
Which strategy should you recommend?

A) Write error messages to the event logs on the local computers. Use Windows Error Reporting to view the error information.
B) Write error messages to the SQL Server databases. Synchronize the databases by using merge replication.
C) Write error messages to the SQL Server databases. Synchronize the databases by using transactional replication.
D) Write error messages to the event logs on the local computers. Use Windows Management Instrumentation (WMI) to view the error information.
