出題：3

XYZ Company has hired you to perform an indoor site survey of their 5-storyfacility. They own the building and rents out unused floors (floors 2 and 4) to other companies, and the other companies already use 802.11 WLANs. XYZ Company wants all of the offices they occupy to be surveyed as part of the project.
What actions should be recommended as part of the site survey project? (Choose 2)

A. Determine how much signal strength is passing between floors.

B. Identify security best practice violations on neighboring WLANs.

C. Verify that RF signals from XYZ Company's APs are not penetrating outside the perimeter of the building.

D. Verify that XYZ Company's APs are not directly above or below APs on adjacent floors.

E. Locate wiring closets on each floor occupied by XYZ Company.
