Selected Answer: A

Port security is a feature on network switches that restricts access to a network by limiting the devices that can connect to a specific Ethernet port. By configuring port security, administrators can: Restrict which MAC addresses are allowed on a port. Disable unused ports to prevent unauthorized access. Set up actions (e.g., shutting down the port) when a violation is detected. This would prevent an unauthorized device from connecting to an unused Ethernet port and gaining access to the network
