Enhance your career with CWAP-404 PDF Dumps – True CWNP Exam Questions [Q57-Q78]

Q57. 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?

Q58. You have been asked to recommend a protocol analysis solution that uses open source software and works with the Linux platform. It must provide decoding of 802.11ac frames and minimal support for reporting and statistics.
What solution would you recommend?

Q59. Given a protocol analyzer can decrypt WPA2-PSK data packets providing the PSK and SSID are configured in the analyzer software.
When performing packet capture (in a non-FT environment) which frames are required in order for PSK frame decryption to be possible?

Q60. 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?

Q61. Given the frame capture and the decode shown,

after which Beacons in the list shown (as indicated by the frame number in the leftmost column) would multicast traffic have been sent in this infrastructure BSS if multicast traffic had been queued for transmission at the access point? (Choose 2)

Q62. What is the function of 802.11 Management frames?

Q63. During a VHT Transmit Beamforming sounding exchange, the beamformee transmits a Compressed Beamforming frame to the beamformer. What is communicated within this Compressed Beamforming frame?

Q64. 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?

Q65. When would you expect to see a Reassociation Request frame?

Q66. You are responsible for troubleshooting and analysis of the WLAN in your organization that supports more than 700 client STAs. Forty APs are deployed and they are all dual-band APs and are controller-based. You must troubleshoot the wired side in some scenarios using a protocol analyzer. Which one of the following problems would warrant wired-side analysis in most situations?

Q67. Given: The Frame Check Sequence (FCS) is a 32 CRC used for error detection.
The CRC is calculated over what?

Q68. During a VHT Transmit Beamforming sounding exchange, the beamformee transmits a Compressed Beamforming frame to the beamformer. What is communicated within this Compressed Beamforming frame?

Q69. In what scenario is Open Authentication without encryption not allowed based on the 802.11 standard?

Q70. In the frame decode shown, there are two sets of supported data rates. 1, 2, 5.5, and 11 Mbps are all shown as “basic” data rates, and 6, 9, 12, 18, 24, 36, 48, and 54 Mbps are shown simply as supported data rates.

What is true of “basic” data rates in this context?

Q71. You are using the real-time FFT display of a spectrum analyzer. In what domain does this show the RF energy detected in the swept frequencies?

Q72. When a 5 GHz HT station in a 40 MHz BSS desires to protect a 40 MHz transmission from an OFDM station using an RTS/CTS or CTS-to-Self exchange, what frame format is used for the RTS and/or CTS frames?

Q73. You are using a laptop-based protocol analyzer to scan all channels and determine the basic configuration of the WLAN Basic Service Set in your facility.
You are scanning all channels. All configured with default settings.
What can you change to cause the scan to run faster while still APs are capturing beacon frames on all the channels?

Q74. What does the value of the Listen Interval field in an Association request frame indicate?

Q75. Which information elements (IE) are contained in an IEEE 802.11 Probe Request frame?
(Choose 2)

Q76. The PHY layer provides framing by adding a header to create what type of data unit?

Q77. 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?

Q78. You have implemented centralized, infrastructure-based spectrum analysis.
The Aps are configured to perform spectrum analysis in an ad-hoc manner and will go offline as Aps to perform this duty when needed.
What unique method of spectrum analysis monitoring is provided by this solution that is not typically available in a laptop-based analyzer?
