Explanation

DHCP reservations (also called static DHCP assignments) bind specific IP addresses to specific MAC addresses in the DHCP server's table. By configuring reservations only for approved devices and disabling the dynamic address pool, the administrator ensures that only pre-registered network interfaces receive IP configuration and can communicate through the router. MAC filtering (C) controls wireless association, not routing; disabling SSID broadcast (B) only hides the network name; and two-factor authentication (D) is an identity control, not a traffic-limiting mechanism.
