Why would a network administrator disable SSID broadcasting on a WLAN?

• A. To save bandwidth
• B. To improve signal strength
• C. To eliminate outsiders scanning for available SSIDs
• D. To allow easier network management

Answer: (C)

Disabling SSID broadcasting on a WLAN is primarily done to enhance network security by making it less visible to unauthorized users. When SSID broadcasting is turned off, the wireless network does not openly advertise its presence, which means that outsiders cannot easily see the network when they scan for available wireless connections. This added layer of obscurity can deter casual attempts to connect to the network, as only users who already know the network name (SSID) will be able to connect. While the other options might seem relevant to network performance or management, they do not accurately reflect the main purpose of disabling SSID broadcasting. For instance, it does not typically save bandwidth or improve signal strength. Instead, the key focus is on reducing the visibility of the network to potential unauthorized users, thereby increasing security.
