（D）MSK

（A）104 ms

（B）10 ms

（C）400 ns

（A）The number of client stations associated to the BSS

（B）The Layer 3 protocol used by each station to transmit data over the wireless link

（C）The power management settings in the access point beacons

（D）The presence of co-located (10m away) access points on non-overlapping channels

（A）One spatial stream, because the definition of the AP indicates that it is capable of only one spatial stream.

（B）Three spatial streams, because the definition of the client indicates that it is capable of only three spatial streams.

（C）Two spatial streams, because the definition of the AP indicates that it is capable of only two spatial streams.

（D）Three spatial streams, because the definition of the AP indicates that it is capable of only three spatial streams.

（A）RF interference from more than 10 nearby Bluetooth transmitters

（B）Increasing the beacon interval from 100 to 200 (TUs)

（C）Increasing or decreasing the number of spatial streams in use by the client station and AP

（D）Use of passphrase authentication instead of 802.1X/EAP authentication

（E）Use of WEP or TKIP for encryption instead of CCMP

（A）Place a call with the handset and move around the facility to test quality during roaming

（B）Use a spectrum analyzer to monitor RF activity during a VoIP call

（C）Use a protocol analyzer to capture the traffic generated when a laptop roams

（D）Use the built-in roaming monitor built into all VoIP handsets

（A）2.4000 - 2.4835 GHz

（B）5.15 - 5.25 GHz

（C）Implementation of several other clients in the same BSS using 802.11g radios.

（D）Implementation Fast BSS Transition (FT) for roaming

（A）The client station transmits a Reassociation Request frame to its currentaccess point.

（B）The new access point transmits a Reassociation Response to the client station with a status value.

（C）The current access point informs the IP gateway of the reassociation.

（D）The current access point triggers the client's reassociation service.

（A）An IBSS does not have a distribution system (DS), but a BSS does.

（B）An IBSS does not support any 802.11ac enhancements, but a BSS does.

（C）An IBSS does not support 802.11 authentication or association, but a BSS does.

（D）An IBSS does not require beacon frames, but a BSS does.
