質問 6：
As a station moves away from the access point to which it is associated, it changes its data rate from 600 Mbps to 540 Mbps and then to 450 Mbps.
What IEEE 802.11 term or phase is used to describe this functionality?
A. Multirate Control

質問 7：
During the discovery and connectivityprocess, client and AP stations exchange information about their supported data rates. After the association, how do client and AP stations select the supported data rate that will be used to send an 802.11 data frame?
A. During the association, the client and AP agree to use thesame transmit rate, but either station can request a change at any time after the association.
B. The client and AP may use different transmit rates, but the AP determines the data rate that will be used by each client station in the BSS.
C. The client and AP each choose the optimal data rate to use independently of one another, based on their own measurements related tothe RF link.
D. The client and AP may use a different transmit rates, but the transmit rate is determined by the peer station, based on the peer's experience of the RF link.
E. The client and AP may use different transmit rates, but the client determines the data rate thatit will use and the datarate that the AP will use when communicating to the client.
正解：C

質問 8：
ABC Company performs government contract work that requires disabling WLANs and has recently purchased an 802.11 Wireless Intrusion Prevention System (WIPS) to enforce their "NO WIRELESS" network security policy.
What attack type cannot be recognized by theWIPS?
A. Rogue APs installation
B. Layer 3 DoS
C. RF jamming
D. Packet capturing
E. Deauthentication
正解：D

質問 9：
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.
正解：A
