Cisco Enterprise Networks SDA, SDWAN and Catalyst Center for System Engineers — Question 33

Which protocol is used between an Endpoint and a Switch with an 802.1 authentication?

Answer options

• A. RADIUS
• B. EAP
• C. MAB
• D. TACACS

Correct answer: B

Explanation

EAP (Extensible Authentication Protocol) is specifically designed for authenticating devices in network environments, such as between an Endpoint and a Switch in 802.1X authentication scenarios. RADIUS, MAB, and TACACS are related but serve different roles; RADIUS is a protocol for remote authentication, MAB is for MAC address-based authentication, and TACACS is typically used for device administration authentication.
