An organization does not have adequate resources to administer its large infrastructure. A security
administrator wishes to combine the security controls of some of the network devices in the
organization. Which of the following methods would BEST accomplish this goal?

A.
Unified Threat Management

B.
Virtual Private Network

C.
Single sign on

D.
Role-based management

Explanation:
When you combine a firewall with other abilities (intrusion prevention, antivirus, content filtering,
etc.), what used to be called an all-in-one appliance is now known as a unified threat management
(UTM) system. The advantages of combining everything into one include a reduced learning curve
(you only have one product to learn), a single vendor to deal with, and—typically—reduced
complexity.
