QUESTION 71When designing a WLAN, AP placement is important. How would you rank the density of APs needed tosupport location services versus data and voice services?

A. Voice and data services both require a higher density of APs than location services.B. Data services have a lower density of APs compared to location services, but more than voice.C. Voice services have the highest density of APs over location and data services.D. Data services have the lowest density of APs compared to location services, which has the

highest density.



QUESTION 72When designing and deploying an outdoor mesh network, what is the appropriate RF cell overlap?

A. 10 percentB. 15 percentC. 20 percentD. 25 percentE. Application dependent



QUESTION 73In performing a post-deployment audit, you are concerned by significant changes in measured RSSI and SNRvalues taken on a wireless client in one location. How do you explain the differences in these values?

A. The differences in the RSSI and SNR values are a result of signal diffusion in the environment.B. The differences in the RSSI and SNR values are a result of multipath in the environment.C. The differences in the RSSI and SNR values are a result of signal absorption in the environment.D. The differences in the RSSI and SNR values are a result of signal diffraction in the environment.



QUESTION 74Which three are logistical issues that need to be taken into consideration prior to performing a site survey?(Choose three.)

A. What level of client density and throughput is expected for each WLAN cell?B. Will security clearances be required to perform the site survey?C. How much time will be required to survey each potential AP location?D. Will contractor badges and employee or union escorts be required while performing the site survey?E. Is access available to customer employees so initial interviews can be performed?F. Will any facility orientation be required prior to performing the site survey?



QUESTION 75When performing a post-installation audit using the Ekahau Survey tool, which four steps are associated withthe 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.
