The correct answer is C. Port security.
Explanation:
Port security is a feature available on most network switches that allows the administrator to limit the number of devices that can connect to a specific switch port. This feature can be configured to prevent unauthorized devices from connecting to the network by limiting the number of MAC addresses that can be associated with a specific port.
When port security is enabled, the switch will monitor the MAC addresses of devices that connect to the port. If an unauthorized device tries to connect to the port, the switch will either block the device from connecting or generate an alert to notify the administrator.
DHCP snooping is a security feature that prevents rogue DHCP servers from distributing incorrect IP address information to clients on the network. This feature is useful in preventing malicious actors from taking control of the network, but it is not directly related to preventing unintended connections.
Geofencing is a technology that uses GPS or RFID to create a virtual boundary around a physical location. It is often used in mobile applications and has limited application in network security.
Secure SNMP is a protocol used to manage network devices. While securing SNMP is important, it is not directly related to preventing unintended connections to a network switch.
Therefore, port security is the best option to prevent unintended connections to a network switch.
