Which technology is BEST for port-based authentication to ensure that network clients authenticate before use?
The correct answer is C. 802.1x. IEEE 802.1X is the standard specifically designed for port-based Network Access Control (NAC). It requires clients to authenticate (typically via RADIUS and EAP) before being granted access to a network port, whether wired or wireless. 802.3 (A) is the Ethernet standard for…

Explanation
IEEE 802.1X is the standard specifically designed for port-based Network Access Control (NAC). It requires clients to authenticate (typically via RADIUS and EAP) before being granted access to a network port, whether wired or wireless. 802.3 (A) is the Ethernet standard for wired networking with no built-in authentication. 802.15.1 (B) is the Bluetooth standard. 802.11g (D) is a Wi-Fi standard defining wireless transmission speeds. None of these address port-based authentication the way 802.1X does.
