A user would like to allow all of the devices on a home network to connect to the WAP except for smart phones. Which of the following features should be used to accomplish this?
The correct answer is D. Exclude smart phones from the MAC filter list. MAC address filtering on a WAP allows an administrator to selectively permit or deny specific devices by their hardware address, making it the right tool for blocking only smartphones.

Why each option
MAC address filtering on a WAP allows an administrator to selectively permit or deny specific devices by their hardware address, making it the right tool for blocking only smartphones.
A unique DHCP scope ID controls IP address assignment pools, not which devices can associate with the WAP at the wireless level.
Changing the SSID renames the wireless network for all devices equally and does not selectively block any device type.
Changing the channel to match the smartphones' frequency would increase interference with those devices but would not reliably or cleanly prevent them from connecting.
MAC address filtering on a WAP lets an administrator create an exclusion list of specific hardware addresses. By adding the MAC addresses of the smartphones to a deny/exclusion list, only those devices are blocked while all other devices remain able to connect.
