Explanation

MAC (Media Access Control) filtering allows the router to maintain an allowlist of approved device hardware addresses, blocking any device whose MAC address is not on the list. This directly addresses the concern about unauthorized devices. Removing patch cables only prevents wired connections in specific ports but does not stop wireless or other wired access. Locking the router and switches in a room secures the hardware from physical tampering but does not control which devices can connect logically. Disabling DHCP prevents automatic IP assignment, but a determined user can still set a static IP and gain access - it is not a true access control mechanism.
