Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 254

What is a difference between TACACS+ compared to RADIUS? (Choose two.)

Answer options

• A. TACACS+ encrypts only the password, and RADIUS encrypts the entire packet payload.
• B. TACACS+ uses a connection-oriented transport, and RADIUS uses a connectionless transport.
• C. TACACS+ supports 802.1X network access control, and RADIUS supports only MAB.
• D. TACACS+ offers multiple protocol support, and RADIUS supports only IP traffic.

Correct answer: B, D

Explanation

The correct answers are B and D because TACACS+ indeed uses a connection-oriented transport while RADIUS is connectionless. Additionally, TACACS+ supports multiple protocols, whereas RADIUS is primarily designed for IP traffic only. The other options incorrectly describe the encryption methods and capabilities of each protocol.
