Pete, a security auditor, has detected clear text passwords between the RADIUS server and the authenticator. Which of the following is configured in the RADIUS
server and what technologies should the authentication protocol be changed to?

A.
PAP, MSCHAPv2

B.
CHAP, PAP

C.
MSCHAPv2, NTLMv2

D.
NTLM, NTLMv2

Explanation:
PAP transmits the username and password to the authentication server in plain text. MSCHAPv2 is utilized as an authentication option for RADIUS servers that are
used for Wi-Fi security using the WPA-Enterprise protocol.
Incorrect Answers:
B, C: The scenario mentions that passwords between the RADIUS server and the authenticator are transmitted in clear text. Then the first part of the question asks
what is configured for the RADIUS server. The first part of these two options is CHAP and MSCHAPv2, which do not transmit in clear text.
D: NTLM is a suite of Microsoft security protocols that provides authentication, integrity, and confidentiality to users.
