Answer: C

Explanation:

Port security is a feature that restricts input to a switch port by limiting and identifying MAC

addresses of the devices allowed to access the port. This prevents unintended connections from

unauthorized devices or spoofed MAC addresses. Port security can also be configured to take actions

such as shutting down the port or sending an alert when a violation occurs.
