Which of the following options is a functionality or tool that disallows access to a wireless network based on the Layer 2 address of the client device?
ACL
WPA2
Split tunnel VPN
MAC address filtering
Layer 2 addresses-also called physical or MAC addresses-identify the network interface of a device. MAC address filtering restricts wireless access to devices whose MAC addresses appear on an allow-list (or blocks those on a deny-list). Although this control can deter casual or accidental connections, it is easily bypassed through MAC-address spoofing, so it should never be the sole means of protecting a network.
