CompTIA Network+ (N10-008) — Question 312

A client who shares office space and an IT closet with another company recently reported connectivity issues throughout the network. Multiple third-party vendors regularly perform on-site maintenance in the shared IT closet. Which of the following security techniques would BEST secure the physical networking equipment?

Answer options

Correct answer: A

Explanation

Disabling unneeded switchports is the best option as it prevents unauthorized devices from connecting to the network, thereby enhancing security. Role-based access is relevant for user permissions but does not directly protect physical equipment. Enabling logging helps in monitoring but does not prevent access, while configuring an access control list is more about controlling traffic rather than securing physical hardware.
