CompTIA Network+ (N10-008) — Question 373

A network administrator notices excessive wireless traffic occurring on an access point after normal business hours. The access point is located on an exterior wall. Which of the following should the administrator do to limit wireless access outside the building?

Answer options

• A. Set up a private VLAN.
• B. Disable roaming on the WAP.
• C. Change to a directional antenna.
• D. Stop broadcasting of the SSID.

Correct answer: C

Explanation

The correct choice is C, as a directional antenna will focus the wireless signal inward towards the building, reducing coverage outside. Options A and B do not directly address limiting external access, and option D could hinder legitimate users within the building from connecting to the network.
