DF /Reference: : QUESTION 75 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. Correct Answer: ABDE /Reference:
