Implementing Cisco Secure Access Solutions (SISAS, legacy) — Question 52

Which protocol sends authentication and accounting in different requests?

Answer options

• A. RADIUS
• B. TACACS+
• C. EAP-Chaining
• D. PEAP
• E. EAP-TLS

Correct answer: B

Explanation

TACACS+ is the correct answer because it distinctly handles authentication and accounting in separate requests, enhancing security and flexibility. In contrast, RADIUS combines authentication and accounting, while EAP-Chaining, PEAP, and EAP-TLS are related to authentication methods rather than the separation of requests.
