When IIS is running multiple websites, what do you use to isolate one site from another website?
B. application pools
D. virtual directories
An application pool is a set of resources (a worker process or a set of worker processes) used by a website
or application that defines the memory boundaries for the site. Forcing each application to have its own
application pool ensures that one site does not interfere with another site on the same server, which
ensures application performance and improved application availability.
Therefore, if one application has a memory leak or crashes, it will not affect the other sites.
