Exam N10-008 topic 1 question 611 discussion

A. Port security Port security is a feature that can be implemented on network switches to control which devices are allowed to connect to the network through a specific port. It allows network administrators to specify the number of allowed MAC addresses on a port, and it can shut down the port or take other actions if it detects unauthorized devices. In this scenario, port security could have prevented the unauthorized personal laptop from connecting to the corporate LAN, as the port would have been configured to only allow the authorized MAC addresses associated with the company's devices. Therefore, the correct answer is A. Port security.
