300-370 · Question #172

Which two parameters must be considered when evaluating for severity on a Wi-Fi interferer? (Choose two.)

The correct answer is D. broadcast frequency E. dBm. To assess the severity of a Wi-Fi interferer, its broadcast frequency must be evaluated to identify potential channel overlap, and its signal strength (dBm) must be measured to quantify the intensity of the interference.

Why each option

To assess the severity of a Wi-Fi interferer, its broadcast frequency must be evaluated to identify potential channel overlap, and its signal strength (dBm) must be measured to quantify the intensity of the interference.

Anumber of active wireless clients

The number of active wireless clients reflects the scale of devices affected by interference, not an intrinsic parameter of the interferer itself that determines its severity.

BOS of the affected wireless clients

The operating system of affected wireless clients is irrelevant to the physical characteristics and severity of a Wi-Fi interferer, as interference is a physical layer phenomenon.

Clocation in the wireless infrastructure

While the physical location of the interferer influences its impact, 'location in the wireless infrastructure' is not a direct, quantifiable parameter of the interferer's inherent severity in the same way frequency and power are.

Dbroadcast frequencyCorrect

The broadcast frequency of an interferer is a primary factor in determining severity because interference occurs when signals operate on the same or adjacent frequency channels as the legitimate Wi-Fi network, causing signal collisions and degradation.

EdBmCorrect

dBm (decibel-milliwatts) is a measure of the absolute power level of the interferer's signal. A higher dBm value indicates a stronger interfering signal, which will more severely degrade the signal-to-noise ratio (SNR) of Wi-Fi transmissions and significantly impact network performance.
