b. ICMP
c. FTP
d. Telnet

Answer 1

RADIUS (Remote Authentication Dial-In User Service) is the service often used with 802.1x port security for wired and wireless LANs to provide centralized user authentication and access management.

Step-by-step explanation:

The service that is commonly used with 802.1x port security for both wired and wireless LANs, even though it was originally designed to support remote dial-in access to a corporate network, is RADIUS (Remote Authentication Dial-In User Service).

RADIUS is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service. Due to its versatility and ability to manage access to networks, RADIUS has become commonly integrated with 802.1x port security. It offers a way to effectively ensure that only authenticated users can access the local network resources.
