You are planning a development environment to create custom solutions for a production SharePoint 2010 farm.
The plan needs a software tool to help diagnose application bugs introduced through custom code and provide
information about the page rendering time from the Web request to the database query. Developers need to
isolate problems and diagnose excessive execution times in the following items:
Page request
.SPRequest
.Microsoft SQL Server 2008
You need to recommend a way for developers to identify if a value exceeds acceptable ranges in the items listed in the requirements.
What should you tell the developers to do?

A.
Use the Object Explorer component of SQL Server Management Studio to configure the SQL Server Agent properties to Include execution trace messages.

B.
Enable the developer dashboard for the development environment to display the required information on all pages.

C.
Enable the Developer Tools in Microsoft Internet Explorer 8. Open the Script tab and click Start Debugging.

D.
Enable the Developer Tools in Internet Explorer 8. Set up live editing of cascading style sheets (CSS) and click a property name, value, or selector.
Then type a new value and press Enter.
