Refer to the exhibit. Which area indicates the greatest impact on the wireless network when viewing the Cisco CleanAir Zone of Impact map of interferers?

Area A on the Zone of Impact map displays lighter shading, representing a lower interference intensity and therefore a less severe impact on wireless operations in that zone.

Area B shows a partial or moderate interference overlay that does not represent the peak impact region visible on the CleanAir map exhibit.

Area C indicates an intermediate level of RF interference severity that is less concentrated and less impactful than the zone represented by area D.

The Cisco CleanAir Zone of Impact map uses graduated color overlays to visualize interference severity radiating from a detected RF interferer. Area D displays the darkest or most concentrated shading, indicating the highest level of RF degradation in that zone. Wireless clients or APs located within area D experience the most significant performance impact from the interfering device.
