   A home user wants to prevent a neighbor from connecting to their Wi-Fi. The user has already set a strong WPA2 passphrase. They ask if MAC address filtering would add a useful layer. What is the most accurate advice?

   • AIt can help, but an attacker can spoof an allowed MAC address, so it should not be the only protection.
   • BIt is unnecessary because WPA2 already provides perfect security.
   • CIt will block all devices that are not on the list, including the neighbor's, with no way around it.
   • DIt will completely prevent unauthorized access because MAC addresses cannot be changed.
