Correct Answer: B QUESTION 37

27 You have a multinational customer that would like you to perform a wireless site survey for a new manufacturing facility in Singapore. They have had a local vendor install a point-to-point wireless bridge link between two buildings 1 km apart. The ground between the buildings is flat but because facilities are in the mountains, dense fog is an issue. There are no line of sight issues between the buildings. The link is experiencing errors and throughput issues. Currently the two radios are set to operate at 2.4 GHz and the transmit power is set to 7 dbm with 7 dbm antennas. What do you need to take into consideration when performing the site survey for this link? "First Test, First Pass" 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. Correct Answer: D QUESTION 38 Which 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.
