SharePoint 2013 Business Intelligence Quiz Questions and Answers
Answer :
All applications share a common worker process
Explanation :
An Application Pool can contain one or more web applications and since each web application is associated with its own worker process, we can say that an Application Pool isolates web applications thereby isolating the worker processes also.
Application Servers have services running on them and provide specific services such as Search, User Profile, Usage and Health Data Collection Services etc.
w3wp.exe is a windows process which runs Web applications, and is responsible for handling requests sent to a Web Server for a specific application pool.
