The 802.1AE standard, also known as MACSec (Media Access Control Security), provides encryption and message integrity to prevent unauthorized access and tampering of LAN traffic. It includes a feature called Secure Association Key (SAK), which allows a switch to verify the identity of a sender and prevent false supervisory messages. The 802.1X standard, on the other hand, provides port-based authentication for devices connecting to a LAN and does not directly address the issue of supervisory message authentication. Therefore, choice A (802.1X) is incorrect. Choice C (Both A and B) is also incorrect because only 802.1AE addresses the specific concern of preventing false supervisory messages. Choice D (Neither A nor B) is incorrect because 802.1AE does provide the relevant feature.
