Exam 350-701 topic 1 question 278 discussion

The missing port configuration is C. dot1x pae authenticator. In order to successfully configure wired 802.1x on a network, the port must be configured as a PAE (Port Access Entity) authenticator. This is accomplished using the "dot1x pae authenticator" command in the switch configuration. The PAE authenticator is responsible for managing the 802.1x authentication process, including sending and receiving EAP (Extensible Authentication Protocol) messages, and determining whether a device should be granted access to the network based on its authentication credentials. Without the "dot1x pae authenticator" configuration, the laptop will not be able to authenticate and gain access to the network.
