Q91. Which statement best describes an outdoor RF point-to-point antenna deployment? 

A. Both antennas must be vertically polarized. 

B. Both antennas must be horizontally polarized. 

C. There should be a 90 degree difference between antennas for best results. 

D. There should be a 180 degree difference between antennas for best results. 

E. It does not matter so long as both antennas have matching polarization. 

Answer: E 

Q92. When performing a post-installation audit using the Ekahau Survey tool, which four steps are associated with the passive portion of the audit? (Choose four.) 

A. Check that all channels are supported by the APs regardless of client capabilities. 

B. Check for co-channel interference by standing near an access point on one channel and watching for other access points that are on the same channel. 

C. Verify that the real-world network traffic (for example, physical data rate, packet loss, etc.) meets user requirements. 

D. When you have completed the post-installation surveys, compare them to the surveys that were performed before the installation. They should look nearly identical. 

E. Check to see if the signal levels on other access points that are heard on the same channel are at least 19 dBm weaker than the access point that you are next to. 

F. Survey by SSID to ensure that smooth roaming is taking place. 

Answer: A,B,D,E 

Q93. When does the curvature of the earth become a factor in an outdoor RF point-to-point link? 

A. 4 miles 

B. 7 miles 

C. 10 miles 

D. 12 miles 

E. 15 miles 

Answer: B 

Q94. You have a customer that is building a new campus of four 3-story buildings that you have just completed the site survey for. The customer is interested in the amount of rack space they will need to allocate in either the building MDF or in the data center for controllers. Each building is going to require 75 APs to support voice and data. How should the controllers be deployed to provide the least number of controllers, the highest redundancy, and the easiest management? 

A. Use the distributed deployment method in each building MDF with the N + N redundancy method. 

B. Use the centralized deployment method in the data center with the N + N + 1 redundancy method. 

C. Use the distributed deployment method in each building MDF with the N + 1 redundancy method. 

D. Use the centralized deployment method in the data center with the N + 1 redundancy method. 

E. Use the distributed deployment method in each building MDF with the N + N +1 redundancy method. 

F. Use the centralized deployment method in the data center with the N + N redundancy method. 

Answer: B 

Q95. You have a customer that operates a large open pit coal mine in the western United States. They need to deploy a wireless point-to-point bridge link across the mine. The distance of the link is 1.5 miles. Which three things do you need to consider prior to performing the site survey for this bridge link? (Choose three.) 

A. What specific EPA training will be required prior to entering the customer site? 

B. Is a specific Mine Safety and Health Administration training course and certificate required prior to entering the customer site? 

C. What specific FCC training will be required prior to entering the customer site? 

D. Will any specialized equipment or clothing will be required to perform the site survey? 

E. Will customer escorts be needed during the site survey? 

Answer: B,D,E

A. 2 degrees 

B. 5 degrees 

C. 10 degrees 

D. 15 degrees 

Answer: B
