The correct answer is B. SSID configuration , because controlling SSID visibility and behavior directly affects which wireless networks devices can see and attempt to join. In shared office environments, multiple Wi-Fi networks may be present, increasing the risk of users accidentally connecting to the wrong network.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , SSIDs define how wireless networks are advertised and discovered. By modifying SSID settings—such as disabling broadcast or restricting auto-join behavior—technicians can prevent devices from attempting to connect to unauthorized or unintended networks.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that MDM solutions often preconfigure approved wireless profiles. Adjusting SSID configuration ensures devices only recognize and connect to sanctioned networks, reducing accidental associations and security risks.

The Mike Meyers / Mark Soper Lab Manual clarifies that IP filtering, content filtering, and port forwarding are network traffic control mechanisms. They do not prevent a device from seeing or attempting to connect to nearby Wi-Fi networks.

Because the goal is to prevent accidental Wi-Fi access , not filter traffic after connection, modifying SSID configuration is the correct and most effective solution.
