3.
D. CAPWAP is an Internet Engineering Task Force (IETF) standard for control messag-
ing for setup, authentication, and operations between access points (AP) and WLAN
controllers (WLC).
4.
B. The service-port interface is an optional interface that is statically configured for
out-of-band management.
5.
B. The Cisco Catalyst 3750 Integrated WLC supports up to 50 APs.
6.
C. With N+N+1 redundancy, an equal number of controllers back up each other, as
with N+N. Plus, a backup WLC is configured as the tertiary WLC for the access
points.
7.
B. The recommended best practice is up to 20 WLAN clients.
8.
D. Mesh access points (MAP) connect to the RAP to connect to the wired network.

6.
False. With split-MAC, control and data traffic frames are split. LWAPs communicate
with the WLCs with control messages over the wired network. LWAPP data messages
are encapsulated and forwarded to and from wireless clients.
7.
Tr ue. Cont roller MAC func t ion s are as s oc iat ion reque sts, re s ource re s er vat ion, and
authentication and key management.
8.
C. Layer 3 CAPWAP tunnels are the preferred solution.
9.
B. Layer 2 intercontroller roaming is the preferred intercontroller roaming option.
10.
B. The WLC places the user data on the appropriate VLAN and forwards the frame to
the wired network.
