XYZ Company is planning to install a new 802.11 WLAN, but wants to upgrade its wired
infrastructure first to provide the best user experience possible. XYZ has hired you to perform the
RF site survey. During the interview with the network manager, you are told that the new Ethernet
edge switches will support VoIP phones and 802.11 access points, both using 802.3af PoE.
After hearing this information, what immediate concerns do you note?
Given: XYZ Company has decided to install an 802.11 WLAN system that will support 1000
wireless users, but they are concerned about network security. XYZ is interested in deploying

control, XYZ would like to support management frame protection as well as a fast secure roaming
protocol for future mobile handsets.
As XYZ Company selects a product to deploy, what two IEEE amendments should be supported
to provide the management frame protection and fast secure roaming security features? (Choose
