CWNP Certified Wireless Analysis Professional 認定 CWAP-405 試験問題 (Q134-Q139):

質問 # 134
A STAs Network Allocation Vector (NAV) is updated by which field in RTS and CTS frames?

A. Duration
B. NAV
C. Timestamp
D. Length

正解：A

解説：
The Duration field in RTS and CTS frames specifies the amount of time the medium will be reserved for the ensuing transmission. Other STAs use this value to update their Network Allocation Vector (NAV) to avoid transmitting during that period.

質問 # 135
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?

A. The tablets are connecting to the wrong SSID
B. The tablets are entering power save mode and failing to wake up to receive the access points transmissions
C. A high noise floor has resulted in a SNR of less than 20dB
D. There is a power mismatch between the APs and the clients

正解：C

解説：
Spectrum analysis can reveal elevated RF energy across the band even when no distinct interference signatures are present. A persistently high noise floor reduces the signal-to-noise ratio, and if the SNR drops below a usable threshold, clients may fail to reliably detect and decode frames needed to connect and maintain service, despite a survey showing adequate coverage levels.

質問 # 136
IEEE 802.11-2007 specifies two ERP protection mechanisms: RTS/CTS and CTS-to-Self. Which statement is true regarding these two protection mechanisms? (Choose 2)

A. Aside from the Subtype subfield of the Frame Control field, the generic MAC header format of RTS and CTS frames are identical.
B. RTS and CTS frames are relayed through the access point, whereas the CTS-to-Self frames are not.
C. By definition, all associated client stations in a BSS can hear RTS, CTS, and CTS-to-Self frames, so RTS/CTS and CTS-to-Self mechanisms have equal effectiveness.
D. A CTS-to-Self frame sent by a client station may reach fewer nodes than the RTS/CTS frame exchange.
E. Use of RTS/CTS requires more overhead than CTS-to-Self due to a higher number of frames transmitted onto the wireless medium.
F. RTS and CTS frames use Short Interframe Spaces (SIFS), and CTS-to-Self frames use PCF Interframe Spaces (PIFS).

正解：D、E

質問 # 137
Given: A MU-MIMO sounding exchange includes the AP transmitting an NDP Announcement frame followed by the NDP and the MU-STAs response with a Compressed Beamforming Frame containing the Feedback matrix.
How often does this MU-MIMO sounding exchange happen?

A. Before every SU-MIMO frame transmission
B. Once for each MU-MIMO group
C. At regular intervals
D. Never; this exchange is only used by UL OFDMA

正解：C

解説：
MU-MIMO sounding exchanges occur at regular intervals to update the AP on the channel conditions for multiple client stations. This ensures that the AP has up-to-date channel state information to optimize beamforming and maintain high multi-user throughput.

質問 # 138
You view a protocol analyzer capture decode with the following protocol frames listed in the following order (excluding the ACK frames): 1) 802.11 Probe Request and 802.11 Probe Response 2) 802.11 Auth and another 802.11 Auth 2) 802.11 Assoc Req and 802.11 Assoc Rsp 4) EAPOL-Start 5) EAP Request and EAP Response 6) EAP Request and EAP Response 7) EAP Request and EAP Response 8) EAP Request and EAP Response 9) EAP Request and EAP Response 10) EAP Success 19) EAPOL-Key (4 frames in a row) What are you seeing in the capture file?

A. WPA2-Enterprise authentication
B. Wi-Fi Protected Setup with PIN
C. WPA2-Personal authentication
D. 802.1X with Dynamic WEP

正解：A

質問 # 139
