Supposed you are the Chief Network Engineer of a certain Telco. Your company is planning for a big business
expansion and it requires that your network authenticate users connecting using analog modems, Digital
Subscriber Lines (DSL), wireless data services, and Virtual Private Networks (VPN) over a Frame Relaynetwork. Which AAA protocol would you implement?
A.
TACACS+
B.
DIAMETER
C.
Kerberos
D.
RADIUS
Answer: A TACACS+
RADIUS only encrypts the passwords, while TACACS+ encrypts the contents of the entire packet, so it is more secure.
Ok. I over-thought this. TACACS+ is Cisco-proprietary, and encryption is not the point of the question, so RADIUS is the answer! Soz, mates!
