質問 8

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 standardized security features. In addition to WPA2-Enterprise with PEAP and role-based access 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, which are included in
802.11- 2016, should be supported to provide the management frame protection and fast secure roaming security features?

（A）802.11r and 802.11w

（B）802.11j and 802.11k

（C）802.11r and 802.11k

（D）802.11z and 802.11w

質問 12

XYZ Corporation is experiencing connectivity problems with their existing building-to-building bridge link. A concrete wall on the roof of one building is partially blocking the Fresnel Zone, and the connection is dropping many frames. The administrator moves the antenna to an area not obstructed by the concrete wall and then realizes the RF cable cannot reach the new location.
If an extension cable is added to move the antenna, what are the likely results?

（A）The Equivalent Isotropically Radiated Power (EIRP) will decrease.

（B）The data throughput rate will increase because VSWR will decrease.

（C）The antenna's azimuth beamwidth will decrease.

（D）The size of the Fresnel zone will increase.

（E）The likelihood of a direct lightning strike will increase.
