Joe, a user, wants to secure his home wireless network and allow only certain devices access to the network. Which of the following measures would be the MOST effective means of limiting access?

Turning off DHCP prevents automatic IP assignment but does not block access, as a savvy user can manually assign a valid static IP and still connect.

MAC filtering works by maintaining a whitelist of approved device hardware (MAC) addresses on the wireless router, preventing any device whose MAC address is not on the list from associating with the network. This directly controls which physical devices are permitted to connect, making it more effective than obscurity-based measures.

Disabling the DMZ affects how traffic is routed to an internal host from the internet and has no effect on which wireless clients can join the local network.

Disabling SSID broadcasting hides the network name but does not prevent access, as the SSID can still be discovered with wireless scanning tools.
