Which two protocols are used by an administrator for authentication and configuration on access points? (Choose two.)

802.1Q is a VLAN tagging standard used for segmenting networks, not for administrator authentication or configuration.

RADIUS (Remote Authentication Dial-In User Service) is a centralized authentication, authorization, and accounting (AAA) protocol often used to authenticate network administrators logging into network devices, including access points.

Kerberos is a network authentication protocol that works on the basis of 'tickets' to allow nodes communicating over a non-secure network to prove their identity to one another securely, but it's less commonly used directly for administrator login and configuration of network devices compared to RADIUS or TACACS+.

TACACS+ (Terminal Access Controller Access-Control System Plus) is another centralized AAA protocol widely used for authenticating administrators and authorizing their command access on network devices like access points.

802.1x is an authentication framework for port-based network access control, used to authenticate clients to the network (often via RADIUS), but it's not typically used for administrators to authenticate to the AP itself for management purposes.
