CompTIA A+ 220-1102 Practice Question

Disabling SSID broadcast makes the network name invisible to devices scanning for available networks. While this doesn't offer robust security on its own, as knowledgeable intruders can still find the network, it does reduce the visibility of the network to casual or inexperienced users. Changing the SSID, using IP filtering, and enabling a firewall are all valid security measures, but they do not reduce the visibility of the network.
