Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 296

What is an advantage of TACACS+ versus RADIUS authentication when reviewing reports in Cisco ISE?

Answer options

• A. TACACS+ performs secure communication with IPsec, and RADIUS uses DTLS encryption.
• B. TACACS+ reduces authentication latency, and RADIUS increases latency by adding additional packet headers.
• C. TACACS+ provides command accounting, and RADIUS combines authentication and authorization.
• D. TACACS+ uses SSL certificates, and RADIUS does not have encryption.

Correct answer: C

Explanation

The correct answer is C because TACACS+ is designed to provide detailed command accounting features, which is not a function of RADIUS as it combines both authentication and authorization processes. Options A and D incorrectly describe the encryption methods used by TACACS+ and RADIUS, while option B misrepresents the latency characteristics of the two protocols.
