Question 26

You are troubleshooting a WLAN problem and you suspect hidden node as the cause. What should you look for in a protocol analyzer?

A.Frames with the HN bit set to 1

B.Frames with the retry bit set to 0

C.Frames transmitted from the AP without acknowledgement

D.Retransmitted frames from multiple STAs at higher rates than other STAs

Question 27

You are implementing a VHT-capable AP. Which one of the following channels is available in the 802.11-
2016 standard that was not available before the ratification of 802.11 ac?

A.144

B.153

C.56

D.161

Question 28

You are being interviewed by ABC Company for employment as a wireless site survey expert. The interviewing manager asks you what items should be included in a site survey report generated as part of a manual site survey process.
What answer would be accurate?

A.Documentation proving proper entry of wall material types into the site survey software

B.Itemized list of equipment, licenses, and support contracts required for the facility

C.Documentation noting how each WLAN user group will authenticate to the network

D.RF heat map illustrating coverage and signal quality for each frequency band

Question 29

You are troubleshooting a problem with interference from a non-802.11 device. Given that the device is not a WLAN device, you cannot use a protocol analyzer and have chosen to use a spectrum analyzer. You want to view the signal from the interfering device over time to sec the activity that it is generating. What common spectrum analyzer view should you use for this analysis?

A.Clients

B.Real-Time FFT

C.Waterfall/Spectrogram

D.APs

Question 30

When performing a site survey for a Multiple Channel Architecture (MCA) system in a multi-tenant building with five floors, what aspect should you, as the site surveyor, keep in mind?

A.The RF interference caused by passing airplanes supporting on-board Wi-Fi should be a prime consideration.

B.The omni-directional antennas of the access points should be oriented parallel to the floor to maximize the coverage pattern across as many floors as possible.

C.The channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to other floors.

D.The Fresnel Zone is completely blocked between floors so each floor is considered a separate site survey.
