11.
C. Each 4400 series WLC supports 100 APs. 100 APs times 24 controllers in a mobili-
ty group equals 2400.
12.
D. The recommended number of data devices per AP is 20.
13.
B. The recommended number of voice over wireless devices per AP is seven for G.711
and eight for G.729.
14.
C. Cisco Radio Resource Management controls AP radio frequency and power settings.
15.
A. Typically, there is a 1- to 3-ms latency per hop.
16.
D. The RTT between the AP and WLC should not exceed 300 ms.
17.
D. Cisco recommends deterministic controller redundancy.
18.
D. EoIP is the recommended method for guest services.
19.
A. H-REAP with centralized controllers is recommended for branch WLAN design.
20.
B and D. Recommended practices are minimizing intercontroller roaming and centraliz-
ing controller placement.
21.
D. The Cisco 6500 WLC module supports 300 access points.

27.
B. For best performance, 20 MAP nodes or fewer is recommended per RAP.
28.
D. Only answer D has the correct order.
29.
B. Radio Resource Management (RRM) functions include radio resource monitoring,
dynamic channel assignment, interference detection and avoidance, dynamic transmit
power control, coverage hole detection and correction, and client and network load
balancing.
30.
B. Channels 1, 6, and 11 of the ISM frequencies do not overlap.
31.
A. Only answer A is correct.
32.
C. H-LEAP uses mutual authentication between the client and the network server and
uses IEEE 802.1X for 802.11 authentication messaging. H-LEAP uses a RADIUS serv-
er to manage user information.

34.
A and E. DHCP and DNS can be used to find the WLAN controller.
