ABC Company is having VoWiFi latency problems on their 802.11g WLAN. A wireless administrator has
noticed in the phone’s client utilities software that the MAC CRC Error count is higher on stations with
problems than on those client stations without problems.
A high MAC CRC Error count is attributable to which of the following? (Choose 3)
What MAC layer information will a dual-band 802.11n protocol analyzer capture if it is capturing data frames
encrypted with WPA2-Enterprise? (Choose 2)
As it relates to a spectrum analyzer, complete the following sentence.
The ____________ plot always displays the percentage of time (shown on the Y axis) that the overall RF
power is a certain specified threshold (of amplitude) above the noise floor for a given frequency range
(shown on the X axis).
Given: Before installing a Wi-Fi network, ABC Company performed a spectrum analysis looking for
problems. The 2.4 GHz RF spectrum looked like Image-A. After installing an ERP WLAN, ABC Company
performed another spectrum analysis during business hours. The 2.4 GHz RF spectrum then
looked likeImage-B close to an AP on channel 1.
Now the 2.4 GHz RF spectrum looks like Image-C and access points and clients can no longer
communicate on channel 1. What is happening on channel 1?
Given: ABC Company recorded the 2.4 GHz band with a spectrum analyzer prior to installing their ERP
WLAN. Image-A is how the band appeared prior to the WLAN installation. Image-B is how the bandappears now, and all channels on their WLAN have ceased to function.
What is the best explanation as to why their WLAN is no longer functioning properly?
