Exam N10-008 topic 1 question 607 discussion

C. MAC filtering To only allow company-owned devices to associate with the wireless network when using PSKs (Pre-Shared Keys) and in the absence of a network authentication system, the network technician should implement MAC filtering. MAC filtering involves creating a whitelist of allowed MAC addresses (the unique hardware addresses of network interfaces) that are permitted to connect to the wireless network. By configuring MAC filtering on the wireless access point, only devices with MAC addresses specified in the whitelist will be allowed to associate with the network. Therefore, the correct answer is C. MAC filtering.

This is a terrible question. MAC filtering is extremely insecure.

Radius and Tacacs+ can't be used for the captive portal since "a network authentication system does not exist" therefore MAC filtering is the only logical answer.
