An administrator needs to secure RADIUS traffic between two servers. Which of the following is
the BEST solution?
A.
Require IPSec with AH between the servers
B.
Require the message-authenticator attribute for each message
C.
Use MSCHAPv2 with MPPE instead of PAP
D.

IPsec is used for a secure point-to-point connection traversing an insecure network such as the
Internet. Authentication Header (AH) is a primary IPsec protocol that provides authentication of the
sender’s data.
