transmitting data, voice, and video. (1)
asynchronous transmission - CORRECT ANSWER-Data transmission method in which no reference
signal is present. (5)
attenuation - CORRECT ANSWER-Loss of signal strength. (1)
auditing - CORRECT ANSWER-Service that tracks the events, use, and access of network resources
and writes these actions to a log. (7)
authentication - CORRECT ANSWER-Process used to identify a user and ensure the user is who he or
she claims to be; also known as local authentication. (15)
authentication, authorization, and accounting (AAA) - CORRECT ANSWER-Security standard that
consists of three parts: authentication, authorization, and accounting; also known as triple A. (15)

from a special set of IP ad-dresses that have been set aside by IANA when a DHCP server cannot be
reached. (10)
