RADIUS (Remote Authentication Dial-In User Service) (Option B) is a network protocol that allows users to authenticate using their network credentials, such as usernames and passwords, typically stored in a central directory like Active Directory. It ensures that users can log in to the Wi-Fi using their existing network credentials. * AES (Option A) is an encryption standard but does not handle authentication. * TKIP (Option C) is a deprecated encryption protocol and not related to network login management. * WPA3 (Option D) is the latest Wi-Fi security standard but does not specifically handle centralized login management like RADIUS does.
