1.WCS

2.Controller

3.Access point

4.Bridge


A)   1 and 2

B)   2 and 3

C)   1 and 4 only

D)   4 only


Correct Option - B

ExplanationThe Cisco Unified Wireless Solution is a great product, but you must purchase specialized devices. Cisco managed access points and a controller are the devices you need to purchase to run the Unified Wireless Solution.

Q 2
What is the maximum distance with maximum data rate for 802.11g?

A)   About 65-75 feet

B)   About 90-100 feet

C)   About 150 feet

D)   Over 200 feet


Correct Option - B

ExplanationThe IEEE 802.11g standard provides a maximum data rate of up to 54Mbps, but you need to be close to the access point, somewhere around 90 to 100 feet.

Q 3
You are connecting your access point and it is set to root. What does Extended Service Set ID mean?

A) That you have more than one access point and they are in the same SSID connected by a distribution system.

B) That you have more than one access point and they are in separate SSIDs connected by a distribution system.

C) That you have multiple access points, but they are placed physically in different buildings.

D) That you have multiple access points, but one is a repeater access point.


Correct Option - A

ExplanationExtended Service Set ID means that you have more than one access point and they all are set to the same SSID and all are connected together in the same VLAN or distribution system so users can roam.

Q 7
In Cisco's Unified Wireless Solution, what is the split-MAC architecture?

A) The split-MAC architecture uses MAC addresses to create a forward/filter table and break up collision domains.

B) The split-MAC architecture allows the splitting of 802.11 protocol packets between the AP and the controller to allow processing by both devices.

C) The split-MAC architecture uses MAC addresses on the wireless network and IP addresses on the wired network.

D) The split-MAC architecture uses MAC addresses to create a forward/filter table and break up broadcast domains.


Correct Option - B

ExplanationThe split-MAC architecture allows the splitting of 802.11 protocol packets between the Cisco LWAPP-based AP, which handles real-time portions of the protocol, and the WLAN controller, which handles those items that are not time sensitive.
