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. 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.

B. 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.

C. 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.

D. 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.

E. 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.

B. WLAN devices cannot detect collisions and must receive positive frame acknowledgment.

C. Half of the bandwidth is allocated to uplink traffic and half to downlink traffic.

D. Radio receiver hardware cannot process data as quickly as it can be transmitted.

出題：8

ABC Company is planning toinstall a new 802.11ac WLAN, but wants to upgrade its wired infrastructure first to provide the best user experience possible. ABC Company has hired you to perform the RF site survey. During the interview with the network manager, you are told that the newEthernet edge switches will support VoIP phones and 802.11 access points, both using 802.3 PoE.
After hearing this information, what immediate concerns do you note?

A. The power budget in the edgeswitches must be carefully planned and monitored based on the number of supported PoE devices.

B. If the switches are in optimal locations for VoIP phones, they are likely to be suboptimal locations for 802.11 APs.

C. VoIP phones and 802.11 access points should not be powered by the same edge switch dueto distortion.

D. The edge Ethernet switches should support Ether-channel to get the best results out of the network.
