Enabling an allow list (Option D) will limit access to the wireless network by only allowing devices with specified MAC addresses to connect. This is an effective method for minimizing Wi-Fi access in a crowded environment.
* Port forwarding (Option A) controls traffic through specific ports but doesn't minimize wireless access.
* Unused ports (Option B) could refer to physical network ports or firewall settings, unrelated to controlling Wi-Fi access.
* Disabling SSID broadcast (Option C) might hide the network name but doesn't secure access.
