CompTIA Network+ (N10-008) — Question 806

A company is moving to a new building designed with a guest waiting area that has existing network ports. Which of the following practices would BEST secure the network?

Answer options

• A. Ensure all guests sign an NDA.
• B. Disable unneeded switchports in the area.
• C. Lower the radio strength to reduce Wi-Fi coverage in the waiting area.
• D. Enable MAC filtering to block unknown hardware addresses.

Correct answer: B

Explanation

Disabling unneeded switchports is the best practice because it prevents unauthorized access to the network by ensuring that only necessary connections remain active. The other options, such as requiring NDAs or enabling MAC filtering, do not provide the same level of security against unauthorized network access as disabling switchports does. Lowering Wi-Fi coverage may limit access but does not address wired network security.
