Finish the statement: It is possible to distinguish between_______22 MHz transmissions and________20 MHz transmissions when looking at an FFT plot.
You have installed a new 802.1 lac WLAN configured with 80 MHz channels. Users in one area are complaining about poor performance. This area is currently served by a single AP. You take a spectrum analysis capture in the poor performing are a. While examining the waterfall plot you notice the airtime utilization is higher on the first 20 MHz of the 80 MHz channel when compared to the rest of the channel. What do you conclude?
You are troubleshooting a client that is experiencing slow WLAN performance. As part of the troubleshooting activity, you start a packet capture on your laptop close to the client device. While analyzing the packets, you suspect that you have not captured all packets transmitted by the client. By analyzing the trace file, how can you confirm if you have missing packets?
When performing protocol analysis, you capture an 802.1 lac data frame on channel 52, transmitted at MCS 8. At what data rate was the PHY Preamble transmitted?
How many frames make up the Group Key Handshake excluding any Ack frames that may be required?
When performing protocol analysis, you notice a high number of RTS/CTS frames being transmitted on an HT network. You suspect this may be due to HT protection mechanisms. Where in the Beacon frame would you look to determine which one of the four HT protection modes the AP is operating in?
What is the difference between a Data frame and a QoS-Data frame?
A client is operating in an unstable RF environment. Out of five data frames transmitted to the client it only receives four. The client sends a Block Ack to acknowledge the receipt of these four frames but due to frame corruption the Block Ack is not received by the AP. Which frames will be retransmitted'
After examining a Beacon frame decode you see the SSID Element has a length of 0. What do you conclude about this frame?
You're the WLAN administrator for a large retailer based at the HQ in New York. The London-based office has been complaining about WLAN disconnections around lunch time each day. You suspect this might be interference from the staff microwave, how might you test your theory from the New York office?

Answers
D.
To request a list of neighboring STAs which enables the STA to better pick the right protection mechanisms
Suggested answer: C

Explanation:

A STA that supports 802.11k Radio Measurement would send a Neighbor Request to an AP to request a list of neighboring APs which the STA can use as roaming candidates. A Neighbor Request is an Action frame that contains a subelement specifying the type of information that the STA wants to receive from the AP. A Neighbor Report is an Action frame that contains a subelement with a list of neighboring APs that match the criteria specified in the Neighbor Request. The Neighbor Report provides information such as BSSID, channel, operating class, and PHY type of each neighboring AP. This information helps the STA to perform intelligent roaming decisions based on signal quality, load, and compatibility .
