Which two protocols are used by an administrator for authentication and configuration on access points?
Answer says "802.1x, and RADIUS"
Can you please verify.
Answer:
- TACACS+
(Terminal Access Controller Access-Control System Plus – used for administrator authentication and authorization for device configuration.)
- RADIUS
(Remote Authentication Dial-In User Service – also used for authentication, commonly for both administrators and wireless clients.)
❗ Why not the others?
- Kerberos → Used for secure authentication in Active Directory environments, not typically for AP configuration.
- 802.1Q → VLAN tagging protocol, not for authentication/configuration.
- 802.1X → Used for client authentication (not admin configuration).
thanks,
James
