The 802.1X protocol created for wired LANs can work in wireless LANs without significant modification.

• A. TRUE
• B. FALSE
• C. IT DEPENDS
• D. NOT APPLICABLE

Answer: (B)

802.1X is a framework for port-based access control that uses EAP to authenticate a device before it can access the network. In wired networks, the authenticator (often a switch) gates the port, and once authentication succeeds the client can send data.

In wireless, you can use 802.1X as the authentication mechanism, but it isn’t simply dropped in without changes. Wireless adds its own security model and key management (for example, WPA/WPA2 with 802.11i) and handles how encryption keys are distributed and refreshed as devices roam between access points. The authentication handshake in WLANs involves additional steps and integration with the 802.11 security framework, including EAP over 802.11 (EAPOL) exchanges and the setup of PMK/PTK/GTK keys for encryption. So while 802.1X can be used in wireless environments, it requires substantial adaptation and integration with the wireless security framework—it's not a direct, no-modification transfer. Therefore, the statement is not correct.
