Pete, the system administrator, wants to restrict access to advertisements, games, and gambling web
sites. Which of the following devices would BEST achieve this goal?
A.
Firewall
B.
Switch
C.
URL content filter
D.
Spam filter
Explanation:
URL filtering, also known as web filtering, is the act of blocking access to a site based on all or part of the
URL used to request access. URL filtering can focus on all or part of a fully qualified domain name (FQDN),
specific path names, specific filenames, specific fi le extensions, or entire specific URLs. Many URLfiltering tools can obtain updated master URL block lists from vendors as well as allow administrators to
add or remove URLs from a custom list.
Incorrect Answers:
A: The basic purpose of a firewall is to isolate one network from another. Firewalls are available as
appliances, meaning they’re installed as the primary device separating two networks.
B: Switches are multiport devices that improve network efficiency.
D: A spam filter is a software or hardware tool whose primary purpose is to identify and
block/filter/remove unwanted messages (that is, spam).Stewart, James Michael, CompTIA Security+ Review Guide, Sybex, Indianapolis, 2014, pp. 18, 19
