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).
