The functionality of TACACS+ that is not accurate in comparison to RADIUS is that the “TACACS+” does not operates as a software application on a remote access server.
Hence, the correct answer is option “E”.
Explanation of Solution
TACACS+:
TACACS+ stands for Terminal Access Controller Access Control System Plus. It is a security protocol used in AAA framework that gives centralized authentication for users who can gain access to the network.
- It does not operates as a software application on a remote access server whereas RADIUS stands for Remote Authentication Dial-In User Service is an open source can operate as a software application on a remote access server.
Explanation for incorrect options:
TACACS+ relies on TCP, not UDP, at the transport layer whereas RADIUS relies on application layer.
Hence, the option “A” is wrong.
TACACS+ is installed on a router or switch whereas RADIUS is installed on the server.
Hence, the option “B” is wrong.
TACACS+ encrypts all information transmitted for AAA whereas RADIUS encrypts only the password when transmitting sign-in authorizations.
Hence, the option “C” is wrong.
TACACS+ was developed for proprietary use on Cisco products.
Hence, the option “D” is wrong.
