and that they have sufficient ports to support all the new WLAN devices.E. Depending on the type of APs that are planned for, the deployment may require different types of PoE to be

supplied by the LAB switches.

QUESTION 36The customer has an existing 802.11b/g network with Cisco 2500 controllers. The customer would like tomigrate to an 802.11a/b/g/n WLAN. Which network infrastructure issue might impact client performance in thisproposed controller-based solution?

A. The additional application load placed on servers by 802.11n clients.B. A bottleneck may occur if the access switch port to the AP only supports 100 Mb/s full duplex.C. The additional load placed on a RADIUS server by 802.1X authentication traffic on the first work day of each

week.D. The added delay WDS imposes on the client when they roam from one AP to another.


QUESTION 37

You have a multinational customer that would like you to perform a wireless site survey for a newmanufacturing facility in Singapore. They have had a local vendor install a point-to-point wireless bridge linkbetween two buildings 1 km apart. The ground between the buildings is flat but because facilities are in themountains, dense fog is an issue. There are no line of sight issues between the buildings. The link isexperiencing errors and throughput issues. Currently the two radios are set to operate at 2.4 GHz and thetransmit power is set to 7 dBm with 7 dBm antennas. What do you need to take into consideration whenperforming the site survey for this link?


A. Change the radio power to 17 dBm.B. Change the radio power to 20 dBm and replace with a 16 dBm antenna.C. Change the radio power to 29 dBm.D. Change the radio power to 13 dBm.


QUESTION 38Which two issues do access and backhaul radios experience in mesh networks? (Choose two.)

A. The access radio has to connect to two or several points.B. The access cell usually covers more area at ground level that may have more sources of reflection and

interference.C. The access cell radio range is larger than the backhaul radio range, which causes the backhaul cell radio to

suffer from more interference.D. Backhaul radios are a bottleneck for throughput.E. RAPs help MAPs avoid coverage holes.
