However, the automation system has not gone live due to problem with the tablets connecting to the WLAN. The WLAN vendor has been onsite to perform a survey and confirmed good primary and secondary coverage across the facility. As a CWAP you are called in to perform Spectrum Analysis to identify any interference sources. From the spectrum analysis, you did not identify any interference sources but were able to correctly identify the issue. Which of the following issues did you identify from the spectrum analysis?

AThe tablets are entering power save mode and failing to wake up to receive the access points
transmissions

BA high noise floor has resulted in a SNR of less than 20%

CThe tablets are connecting to the wrong SSID

DThere is a power mismatch between the APs and the clients
