1. You are designing a Windows application by using Microsoft .NET Framework 4.
Remote users have limited network connectivity. Users will not have write permissions to
the local file system.
You plan to design the error logging strategy for the application.
You need to ensure that the application can collect error information. You also need to
ensure that the errors can be analyzed from a centralized location. What should you do?

A) Log the errors to a Web service.
B) Use a local log file.
C) Use the Microsoft Sync Framework.
D) Log the errors to the Windows System event log.

2. You are designing a distributed application that will be deployed to 5,000 users worldwide.
Servers on five continents will host the Web services and the Microsoft SQL Server 2008
databases that support the application.
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 SQL Server databases. Synchronize the databases by using transactional replication.
B) Write error messages to the SQL Server databases. Synchronize the databases by using merge replication.
C) Write error messages to the event logs on the local computers. Use Windows Management Instrumentation (WMI) to view the error information.
D) Write error messages to the event logs on the local computers. Use Windows Error Reporting to view the error information.

3. You are designing an application by using Windows Presentation Foundation (WPF), Microsoft .NET Framework 4, and Microsoft SQL Server 2008.

What should you recommend?

A) Implement the IDataErrorInfo interface in the business objects and replace all
ValidationRule elements with Data ErrorValidat ion Rule elements.
