You need to determine the correct wireless LAN topology for use in the Company network.
Which three statements are true about the various WLAN topologies？（）
A. In ad hoc mode， the Independent Basic Service Set （IBSS） is a framework in which mobile clients connect directly without an intermediate access point.
B. In Infrastructure mode， the Basic Service Set （BSS） is a framework in which mobile clients use a single access point for connecting to each other or to wired network resources.
C. In Infrastructure mode， the Extended Services Set （ESS） is a framework in which two or more Basic Service Sets are connected by a common distribution system （DS）.
D. In Infrastructure mode， the Independent Basic Service Setet （IBSS） is a framework in which mobile clients connect directly without an intermediate access point.
E. In ad hoc mode， the Basic Service Set （BSS） is a framework in which mobile clients use a single AP for connecting to each other or to wired network resources.
F. In ad hoc mode， the Extended Services Set （ESS） is a framework in which two or more Basic Service Sets are connected by a common distribution system （DS）

Which two statements are true about these access points？ （）
A. It supports eight different data rates.
B. It is fully backward compatible with 802.11b
C. It provides the same network throughput with 802.11b clients， 802.11g clients， or a mixed environment where both clients are present.
D. It is only compatibly with the 11 Mbps 802.11b transfer rate.
E. It has three non-overlapping channels in its channel options.
Refer to the exhibit.
Which two Lightweight Access Point statements are true？（）
A. An AP that has been upgraded from an autonomous AP to lightweight AP will only function in conjunction with a Cisco Wireless LAN controller.
B. LWAPP increases the amount of processing within the APs， enabling them to support filtering and policy enforcement features.
C. WLAN controllers provide a single point of management.
D. Lightweight APs require local configurations using local management.
E. Real time events such as authentication， security management， and mobility are handled by the lightweight AP.
F. Autonomous APs receive control and configuration information from a WLAN controller.
On the Company wireless LAN， A client is searching for an access point （AP）.
What is the correct process order that this Company client and access point goes through in order to create a connection？（）
A. association request/response， probe request/response， authentication request/response
B. association request/response， authentication request/response， probe request/response
C. probe request/response， authentication request/response， association request/response
D. probe request/response， association request/response， authentication request/response
E. None of the other alternatives apply
Refer to the exhibit. The signal transmitted from the AP is reflected off a wall resulting in multipath interference at the client end.
Which statement is true？ （）
A. The transmitted signal from the AP arrives at the client at slightly different times resulting in phase shifting.
B. If signal 2 is close to 360 degrees out of phase with signal 1， the result is essentially zerosignal or a dead spot in the WLAN.
C. Multipath interference is less of an issue when using a DSSS technology because multipath is frequency selective.
D. If signal 1 is in phase with signal 2， the result is essentially zerosignal or a dead spot in the WLAN.
E. Multipath interference is solved by using dual antennas.
