Final answer:
The limitation of turning off the SSID broadcast from an AP that is NOT true is that it can slow down the network speed.
Step-by-step explanation:
The correct answer is C) It can slow down the network speed. Turning off the SSID (Service Set Identifier) broadcast from an Access Point (AP) does not directly impact the network speed. The SSID broadcast is the name of the wireless network that is visible to users. By turning off the SSID broadcast, the network becomes hidden from casual users, but it does not affect the network speed.
However, the other options mentioned are indeed limitations of turning off the SSID broadcast. For example, it can make it harder for legitimate users to connect since they need to manually enter the network name when it is hidden. It also does not hide the network from hackers, as experienced hackers can still discover hidden networks through other means. Additionally, turning off the SSID broadcast can cause configuration issues for some devices that rely on the broadcast to automatically connect to the network.
