You work as a network technician at Company.com. Your boss is interested in the Aironet
enterprise solutions. What should you tell her regarding this? (Select two)
A.
The Cisco Aironet AP handles real-time portions of the LWAPP protocol, and the
WLAN controller handles those items which are not time sensitive.
B.
A Cisco Aironet AP handles the transmission of beacon frames and also handles
responses to probe-request frames from clients.
C.
Virtual MAC architecture allows the splitting of the 802.11 protocol between the Cisco
Aironet AP and a LAN switch.
D.
A Cisco Aironet solution includes intelligent Cisco Aironet access point (APs) and
Cisco Catalyst switches.
E.
In the Cisco Aironet solution, each AP is locally configured by the use of either a web
interface or the command line interface.
Explanation:
Part 1: When LWAPP was first introduced to the WLAN industry in 2002, it revolutionized the
way WLAN deployments were managed with the concept of a “split MAC” the ability to
separate the real-time aspects of the 802.11 protocol from most of its management aspects
(Figure 3). In particular, real-time frame exchange and certain real-time portions of MACmanagement are accomplished within the access point, while authentication, security
management, and mobility are handled by WLAN controllers.
Part 2: When the wireless station is searching for an access point via its built-in scanning
function, it is in State 1, unauthenticated and unassociated. The station finds an access point
either via listening for an access point’s beacon management frame or through knowing the
access point’s unique network name, otherwise named Service Set IDentifiers (SSID).
Access points send out beacon management frames periodically to allow a station waiting to
connect to find those access points within transmission range. A station wishing to connect
to a particular access point with known SSID sends out a probe request management frame
to locate the desired access point.References:
