* The question asks about the best security feature to provide secure connections and keep the medical data protected for patients who use Wi-Fi in the waiting room of a medical building.
* The answer is isolating the guest network, which means creating a separate network for the guests that has no access to the internal network where the medical data is stored. This way, the guests can use the internet without compromising the confidentiality, integrity, and availability of the electronic protected health information (ePHI).
* Securing SNMP, MAC filtering, and disabling unneeded switchports are also security features, but they are not the best solution for this scenario. Securing SNMP means encrypting the Simple Network Management Protocol, which is used to monitor and manage network devices. MAC filtering means allowing or denying access to the network based on the MAC address of the device. Disabling unneeded switchports means turning off the ports that are not in use to prevent unauthorized access. These features can help prevent unauthorized access to the network, but they do not isolate the guest network from the internal network, which is the main requirement for this question. References:
