Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 298

What is a difference between RADIUS versus TACACS+ with regards to packet encryption?

Answer options

• A. RADIUS encrypts the entire body of the packet, and TACACS+ encrypts the username and password in the access-request packet.
• B. TACACS+ encrypts the entire body of the packet, and RADIUS encrypts the username and password in the access-request packet.
• C. RADIUS encrypts the entire body of the packet, and TACACS+ encrypts only the password in the access-request packet.
• D. TACACS+ encrypts the entire body of the packet, and RADIUS encrypts only the password in the access-request packet.

Correct answer: D

Explanation

The correct answer is D because TACACS+ provides full packet encryption, ensuring that the entire body of the packet is secured. In contrast, RADIUS only encrypts the password and not the entire packet, making it less secure than TACACS+.
