SharePoint relies heavily upon the IIS architecture and the .NET framework. Can you determine the missing term from the paragraph below?
You use a ___ to isolate content. When you create a new ___, you also create a new content database and define the authentication method used to connect to the database. In addition, you define an authentication method to be used by the IIS Web site in SharePoint Server 2010.
That was the correct answer, well done! 
Sorry, that was the wrong answer
