You have a Windows Server 2008 R2 server that has the Web Server (IIS) server role installed. The server hosts multiple Web sites.
You need to configure the server to automatically release memory for a single Web site.
You must achieve this goal without affecting the other Web sites.
What should you do?
A. Create a new Web site and edit the bindings for the Web site.
B. Create a new application pool and associate the Web site to the application pool.
C. Create a new virtual directory and modify the Physical Path Credentials on the virtual directory.
D. From the Application Pool Defaults, modify the Recycling options.
Correct Answer: B
Explanation/Reference:
An application pool is a group of one or more URLs that are served by a worker process or a set of worker processes. Application pools set boundaries for the applications they contain, which means that any applications that are running outside a given application pool cannot affect the applications in the application pool.
Application pools offer the following benefits:
Improved server and application performance. You can assign resource-intensive applications to their own application pools so that the performance of other applications does not decrease.
Improved application availability. If an application in one application pool fails, applications in other application pools are not affected.
Improved security. By isolating applications, you reduce the chance that one application will access the resources of another application.
