Answer / guest
Answer: A
Cisco states, ?CHAP provides protection against playback
attack through the use of a variable challenge value that is
unique and unpredictable. The use of repeated challenges is
intended to limit the time of exposure to any single attack.
The host (or a third-party authentication server such as
Terminal Access Controller Access Control System - TACACS)
is in control of the frequency and timing of the challenges?.
