CWAP: Certified Wireless Analysis Professional v402 — Question 6

You are evaluating a protocol capture file in Wireshark. The following filter is applied: wlan_radio.11ac.bandwidth - - 4
What kind of frames are displayed?

Answer options

• A. Only 40 MHz frames
• B. Only 80 MHz frames
• C. Only frames supporting 4 spatial streams
• D. Only frames supporting 4 radio chains

Correct answer: B

Explanation

The filter wlan_radio.11ac.bandwidth - - 4 specifically targets frames that utilize an 80 MHz bandwidth, which is why option B is correct. Option A is incorrect because it refers to 40 MHz frames, while options C and D relate to the number of spatial streams and radio chains, which are not directly indicated by the bandwidth filter.
