Study the exhibit carefully. You are deploying a site survey for a new implementation and see this information in Cisco Spectrum Expert. Which option is true?
Case Study Title (Case Study):

A. The capture shows radar. It is most probably military radar because of the frequency hopping in the "Swept Spectrogram." The workaround is to disable DFS on the AP.
B. There is general background noise of -70dBm, which is not an issue at all for an 802.11b/g deployment.
C. The location of this capture is most likely near a kitchen, because it is clear that there is a microwave oven disrupting channel 1-13. There will be some packet loss while cooking, which is not a problem, because employees will not be working during lunch time.
D. This is a typical Bluetooth pattern. The source needs to be identified and eliminated because it will affect an 802.11b/g deployment.
