Answer: D - If you do not want your router to broadcast the name of your network, you must disable the SSID broadcast feature.

Key Takeaway: Most wireless access points, APs, and routers automatically transmit the name of the network name (SSID) at regular intervals. This feature of Wi-Fi network protocols is intended to allow clients to dynamically discover and roam between WLANs. For improved security, you can disable this feature to preclude automatic discovery of your WLAN. Once your wireless clients are manually configured with the right SSID, they no longer require these broadcast messages. Disabling the SSID broadcast is just one of many techniques for tightening security on a Wi-Fi network. This technique is not 100% effective, as hackers can still detect the SSID by sniffing different messages in the Wi-Fi protocol.
