CWNP CWSP-207 Exam - Topic 3 Question 26 Discussion

Actual exam question for CWNP's CWSP-207 exam
Question #: 26
Topic #: 3
[All CWSP-207 Questions]

While performing a manual scan of your environment using a spectrum analyzer on a laptop computer, you notice a signal in the real time FFT view. The signal is characterized by having peak power centered on channel 11 with an approximate width of 20 MHz at its peak. The signal widens to approximately 40 MHz after it has weakened by about 30 dB.

What kind of signal is displayed in the spectrum analyzer?

30 dB drop seems suspicious, is that normal?

Definitely not an 802.11a AP, wrong frequency!

Wait, could it be an 802.11g AP instead?

Totally agree, that 20 MHz width is a giveaway!

Looks like a low-power wideband RF attack in 2.4 GHz.

I feel like the peak power on channel 11 suggests it's not just a regular AP. Could it be a low-power wideband RF attack? That sounds familiar from our study sessions.

I remember reading that normal 802.11g APs shouldn't have such a wide signal like that. So, I'm leaning towards option B as well, but I'm not completely confident.

This reminds me of a practice question we did about RF attacks. I think option B could be right since it mentions significant interference in 2.4 GHz.

I'm not entirely sure, but I think the signal width and power drop might indicate some kind of interference rather than a normal access point.

Ah, I think I've got it! The signal characteristics point to an 802.11g access point operating normally in the 2.4 GHz band. The widening is likely due to the nature of the 802.11g standard.

Wait, I'm not so sure. The signal widening could be a sign of a low-power wideband RF attack causing interference in the 2.4 GHz band. I'll need to double-check the details.

I'm pretty sure this is an 802.11a access point operating in the 5 GHz band. The signal width and characteristics match that description.

Okay, let's see. The signal is centered on channel 11 and has a width of 20 MHz, which could indicate an 802.11 device. But the widening to 40 MHz has me a bit confused.

Hmm, this seems like a tricky one. I'll need to think carefully about the signal characteristics to determine the right answer.

Nah, 5 GHz band with a signal that wide? Gotta be an 802.11a AP, no doubt about it.

Hold up, 40 MHz wide after a 30 dB drop? Sounds like a wideband attack to me, better call the cyber police!
