A company wants to use its directory database to authenticate users to its wireless network. Which of the following should the company use to accomplish this task?

Multi-Factor Authentication (MFA) is a security measure that requires more than one form of verification to authenticate a user. While MFA can enhance security, it does not directly serve the purpose of authenticating users to a network without additional systems in place, making it less relevant as a standalone solution in this context.

WPA3 (Wi-Fi Protected Access 3) is a security protocol designed to protect wireless networks by enhancing encryption and security features. However, while it secures the connection, it does not provide user authentication based on a directory database, which is the requirement in the question.

Lightweight Directory Access Protocol (LDAP) is a protocol used to access and manage directory information services. Although LDAP can be used for authentication purposes, it does not handle the authentication process itself for network access like RADIUS does, which is specifically tailored for that role.
