Which statement is true about the Cisco NEAT 802.1X feature?
Click on the arrows to vote for the correct answer
A. B. C. D.B.
Cisco NEAT 802.1X (Network Edge Access Topology) is a network access control (NAC) feature that allows for secure authentication and authorization of devices attempting to connect to a network. The feature provides the ability to enforce policies and control access based on the user, device, and location of the connection.
Regarding the given options, the correct statement is:
D. It supports redundant links between the supplicant switch and the authenticator switch.
Explanation: The NEAT 802.1X feature does support redundant links between the supplicant switch and the authenticator switch. This feature ensures high availability and resiliency by providing backup links in case of link failure or maintenance on any of the active links. The feature uses the IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) to provide redundant link support.
Option A is incorrect because multidomain authentication is supported on the authenticator switch interface.
Option B is incorrect because the NEAT 802.1X feature does not allow a Cisco Catalyst switch to act as a supplicant to another Cisco Catalyst authenticator switch. Rather, it allows a Cisco Catalyst switch to act as an authenticator for supplicant devices.
Option C is incorrect because the NEAT 802.1X feature does not use CDP to send MAC address information of the connected host to the authenticator switch. Instead, the supplicant device sends its MAC address to the authenticator switch in an EAPOL (Extensible Authentication Protocol over LAN) frame during the authentication process.
