A. B. C. D.B.
The correct answer for this question is D. dot1x pae authenticator.
802.1X is a port-based network access control protocol that provides a mechanism for authenticating and authorizing devices attempting to connect to a network. It is used to control access to network resources by enforcing security policies that are defined on the Cisco Identity Services Engine (ISE).
To configure 802.1X on a Cisco switch port, the following steps need to be completed:
Enable 802.1X authentication on the switch port by configuring the port as a port access entity (PAE) authenticator using the "dot1x pae authenticator" command.
Configure the authentication method and server group to be used for 802.1X authentication on the switch by using the "aaa authentication dot1x" command.
Enable the switch to enforce the authentication policy on the switch port by using the "authentication port-control auto" command.
Enable the switch to restrict traffic on the switch port to only authenticated devices by using the "dot1x system-auth-control" command.
Therefore, the correct answer for this question is D. dot1x pae authenticator, as it is the command that enables the switch port to act as a PAE authenticator, which is the first step in configuring 802.1X authentication on a Cisco switch port.
