It becomes a DHCP Relay
What is the default DHCP timer?

WPA uses TKIP and is a subset of the 802.11i standard. True or False?
True
The central office is currently using a combination of 4400 and 2100 series WLAN controllers
running v4.2 and a variety of LWAPP-enabled access points servicing both 2.4 GHz and 5 GHz.
The WLAN deployment has been extended to each remote office by implementing a 526 WLAN
controller running v4.1 and several 521 access points. Wireless client deployment uses EAP-TLS
authentication by use of a centralized RADIUS server plus 802.11n for performance. After the first
remote office deployment, remote office users complain that they are not connecting via 802.11n.
Which will most likely cause this problem?
A. The 521 AP does not support 5 GHz, which prohibits 802.11n.
B. The 521 AP and 526 WLAN controllers do not support AES, which prohibits 802.11n.
C. The 526 WLAN controller does not support external authentication via RADIUS, prohibiting
authentication.
D. The 526 WLAN controller does not support 802.11n with either v4.1 or v4.2.
Pg 169
D. The 526 WLAN controller does not support 802.11n with either v4.1 or v4.2.
How do the characteristics that are available on the Cisco WCS for Linux version differ from those
of the Cisco WCS for Windows version?
A. Cisco WCS for Linux is required for deployments.
B. Assuming that there are no differences in hardware, a Cisco WCS for Linux can support up to
750 wireless LAN controllers. A Cisco WCS for Windows can support up to 250 wireless LAN
controllers.
C. Cisco WCS for Windows includes support for Cisco Spectrum Expert clients. Cisco WCS for
Linux does not support Cisco Spectrum Expert clients.
D. There are no differences in features between the Linux and Windows versions of Cisco WCS.
D. There are no differences in features between the Linux and Windows versions of Cisco WCS.
True or false: A wireless PAN consumes little power from small handheld computer devices.
T/F?
True
In the AP Layer 3 controller discovery process, after the LWAPP Discovery Request is broadcast
on a local subnet, which action will AP take next?
A. Send an LWAPP response to the master controller if known.
B. Send an LWAPP discovery request to controllers learned via OTAP if operational.
C. Wait 5 seconds and resend a Discovery Request to the local subnet.
D. Determine whether the controller responses are the primary controller.
B. Send an LWAPP discovery request to controllers learned via OTAP if operational.

Match the proper relationship between interface description and the appropriate.
- Designed to be analogous to VLANs for wireless LAN client device
- The only port that is active when the controller is in boot mode
- This interface is the only consistentlypingable in-band interface IP address on the Cisco WLC
- Used for Layer 3 communications between the Cisco WLC and the lightweight access points
- Used to support mobility management. DHCP relay, and guest web authencation.
