Pete, an employee, attempts to visit a popular social networking site but is blocked. Instead, a page is displayed notifying him that this site cannot be visited. Which of the following is MOST likely blocking Petes access to this site?
A.
Internet content filter
B.
Firewall
C.
Proxy server
D.
Protocol analyzer
C. Proxy servers
That’s tricky. A blocked site is typical of URL filtering, which are often installed on proxy servers. With a content filterm you can inspect the content and block some parts of it. But you can also block the whole site.
