Question No : 4


A manufacturing facility has installed a new automation system which incorporates an 802.11 wireless network. The automation system is controlled from tablet computers connected via the WLAN.
However, the automation system has not gone live due to problem with the tablets connecting to the WLAN. The WLAN vendor has been onsite to perform a survey and confirmed good primary and secondary coverage across the facility. As a CWAP you are called in to perform Spectrum Analysis to identify any interference sources. From the spectrum analysis, you did not identify any interference sources but were able to correctly identify the issue.
Which of the following issues did you identify from the spectrum analysis?

정답:

Question No : 5


Which common feature of a Spectrum Analyzer would be the best to help you locate a non-802.11
interference source?

정답:

Question No : 6


You have installed a new 802.11ac 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 areA. 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?
A. The AP is misconfigured and needs to be reconfigured to 80MHz operation
B. RRM is enabled and has dynamically picked a 20 MHz channel
C. The first 20 MHz is the AP’s primary channel and higher airtime utilization on the primary channel is normal when an AP Is configured for 80 MHz operation
D. Non Wi-Fi interference is preventing the APs 80 MHz operation

정답: C

Question No : 7


In a Spectrum Analyzer the Swept Spectrogram plot displays what information?

정답:

Question No : 8


ABC International has installed a new smart ZigBee controlled lighting system.
However, the network team is concerned that this new system will interface with the existing WLAN and has asked you to investigate the impact of the two systems operating simultaneously in the 2.4 GHz band. When performing Spectrum Analysis, which question could you answer by looking at the FFT plot?

정답:

Question No : 9


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?

정답:

Question No : 10

정답:

Question No : 12


The network administrator at ABC Engineering has taken a large packet capture from one of their APs running in monitor mode. She has very little knowledge of 802.11 protocols but would like to use the capture file to evaluate the overall health and performance of their wireless network. When she asks your advice, which tool do you recommend she opens the packet capture file with?

정답:

Question No : 13


Which one of the these is the most important in the WLAN troubleshooting methodology among those listed?

정답:

Question No : 14


Protocol analyzers may present field values in either binary, decimal or hexadecimal.
What precedes a
hexadecimal value to indicate it is hexadecimal?

정답:

Question No : 15


You are performing a multiple adapter channel aggregation capture to troubleshoot a VoIP roaming problem and would like to measure the roaming time from the last VoIP packet sent on the old AP’s channel to the first VoIP packet sent on the new AP’s channel.
Which timing column in the packet view would measure this for you?
