CWNP Certified Wireless Analysis Professional 認定 CWAP-405 試験問題 (Q37-Q42):

質問 # 37
Which one of the following is not an 802.11 Management frame?

正解：C

解説：
PS-Poll is a control frame used by a station in power save mode to request buffered frames from the access point. It is not classified as a management frame, whereas Action, Authentication, and Beacon frames are all management frame subtypes.


質問 # 38
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?

正解：B

解説：
One way to confirm if you have missing packets in your packet capture is to look for gaps in the sequence number in MAC headers. The sequence number is a 12-bit field in the MAC header that is used to identify and order data frames within a traffic stream. The sequence number is incremented by one for each new data frame transmitted by a STA, except for retransmissions, fragments, and control frames. The sequence number can range from 0 to 4095, and then wraps around to 0. If you see a jump or a gap in the sequence number between two consecutive data frames from the same STA, it means that you have missed some packets in between. The other options are not correct, as they do not confirm if you have missing packets in your packet capture. CRC errored packets are packets that have been corrupted during transmission and have failed the error detection check. Protocol analyzers may show the number of CRC errored packets in their statistics view, but not the number of missing packets. Retransmissions are an indication of packet loss or collision, but not necessarily of missing packets in your capture.

質問 # 39
You have been hired to troubleshoot a WLAN problem for a government organization. You intended to use a Protocol Analyzer as part of your troubleshooting methodology; however, the customer is concerned about you capturing sensitive data transmitted over the network. Which common protocol analyzer feature could you use to address this concern?

正解：A

解説：
Packet slicing allows the capture tool to record only the initial bytes of each frame (such as MAC headers) while discarding the payload. This ensures that sensitive user data is not captured, addressing security concerns while still providing enough information for WLAN troubleshooting.


質問 # 40
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?

正解：B


質問 # 41
When 802.11 standard compliant AES-CCMP security is being used with IPSec/ESP for layered security, what will a WLAN protocol analyzer see as the security mechanism in use when a user browses to an HTTPS secured web page?

正解：A


質問 # 42
