CWNP Certified Wireless Analysis Professional 認定 CWAP-405 試験問題 (Q100-Q105):

質問 # 100
When using WMM Power Save (WMM-PS), a client requests buffered data frames by sending which type of frame?

A. More Data
B. Trigger
C. NDP announcement
D. WMM Poll

正解：D

解説：
In WMM Power Save (WMM-PS), a client in power-save mode sends a WMM PS-Poll frame to the AP to request delivery of buffered frames for its traffic queues. This allows efficient power management while ensuring timely data delivery.

質問 # 101
Which one of the following portions of information is communicated by bits in the PHY Header?

A. SNR
B. Noise
C. Data rate
D. Signal strength

正解：C

解説：
The PHY header contains signaling bits that indicate transmission parameters such as the modulation and coding scheme, which directly defines the data rate of the frame. This information allows the receiver to correctly interpret how the remainder of the PPDU is encoded and decode the data accordingly.

質問 # 102
The PHY layer provides framing by adding a header to create what type of data unit?

A. MPDU
B. PPDU
C. MSDU
D. PSDU

正解：B

解説：
The PHY layer adds its header and preamble to the PSDU received from the MAC layer, forming a Physical Protocol Data Unit (PPDU). The PPDU is the complete unit transmitted over the RF medium and represents the framed data at the physical layer.

質問 # 103
You are analyzing a packet decode of a Probe Request and notice the SSID element has a length of zero. What do you conclude about the transmitting STA?

A. The STA is discovering a list of available BSSs
B. The STA is operating in Ad-Hoc mode
C. The STA's WLAN adaptor is disabled
D. The WLAN adaptor is configured in promiscuous mode

正解：A

解説：
An SSID element with a length of zero in a Probe Request indicates a broadcast probe. This is used by a station to solicit Probe Responses from any nearby access point, allowing it to discover which BSSs are available without targeting a specific SSID.

質問 # 104
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?

A. Absolute
B. Roaming
C. Delta
D. Relative

正解：C

解説：
The Delta time column displays the time difference between the currently displayed frame and the immediately preceding frame. By identifying the last VoIP packet on the old AP's channel and the first VoIP packet on the new AP's channel, the delta value between those two frames directly represents the roaming interruption time.

質問 # 105
......
