Which of the following components of an all-in-one security appliance would MOST likely be
configured in order to restrict access to peer-to-peer file sharing websites?

A.
Spam filter

B.
URL filter

C.
Content inspection

D.
Malware inspection

Explanation:
The question asks how to prevent access to peer-to-peer file sharing websites. You access a
website by browsing to a URL using a Web browser or peer-to-peer file sharing client software. A
URL filter is used to block URLs (websites) to prevent users accessing the website.
Incorrect
A: A spam filter is used for email. All inbound (and sometimes outbound) email is passed through
the spam filter to detect spam emails. The spam emails are then discarded or tagged as potential
spam according to the spam filter configuration. Spam filters do not prevent users accessing peerto-peer file sharing websites.
C: Content inspection is the process of inspecting the content of a web page as it is downloaded.

The content can then be blocked if it doesn’t comply with the company’s web policy. Contentcontrol software determines what content will be available or perhaps more often what content will
be blocked. Content inspection does not prevent users accessing peer-to-peer file sharing
websites (although it could block the content of the sites as it is downloaded).
D: Malware inspection is the process of scanning a computer system for malware. Malware
inspection does not prevent users accessing peer-to-peer file sharing websites.
