NCTI Introduction To Networking – Wireless Practice Test

What is the purpose of disabling WPS on a wireless router?

WPS improves speed. WPS is required for WPA3. WPS is used only for 5 GHz. WPS has known vulnerabilities that can allow easy access; disabling it improves security.

Correct Answer:

WPS has known vulnerabilities that can allow easy access; disabling it improves security.

Explanation:

Disabling WPS centers on reducing a security risk. WPS was meant to make it easier to connect devices, but it has vulnerabilities that can let an attacker bypass normal authentication and join the network. The WPS PIN feature, in particular, can be brute-forced more easily than standard WPA2/WPA3 connections, giving an intruder access without knowing your actual passphrase. By turning WPS off, you remove that attack path, improving overall security. WPS does not affect speed, and it isn’t required for WPA3—WPA3 uses its own secure setup SAMPLEmethods. WPS also isn’t limited to 5 GHz; it can be present on both bands, so disabling it eliminates a potential weak link across the network.
