CompTIA Network+ (N10-007) — Question 503

A network technician needs to implement a network security control on a switch. The solution needs to be non-invasive and prevent guests and unauthorized users from accessing the company's network. Which of the following would BEST meet these requirements?

Answer options

Correct answer: B

Explanation

Disabling unused ports is the best option as it directly prevents unauthorized access by ensuring that only active ports can be used to connect to the network. Upgrading firmware, reconfiguring the router access list, and patching are all important security measures but do not specifically address the immediate need to block guest access on the switch.
