What is an advantage of CHAP over PAP?
A. Passwords are stored on separate servers in encrypted form
B. CHAP sends passwords unencrypted to save connection time
C. CHAP does not attempt to verify whether the user is
authorized to access the requested resource
D. ID?s and passwords are automatically stored in cache
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?.
