CWNP Certified Wireless Analysis Professional 認定 CWAP-404 試験問題 (Q69-Q74):

質問 # 69
What does the value of the Listen Interval field in an Association Request frame indicate?

A. How long a STA waits for an Ack before retransmitting the frame
B. How often a STA will go off channel to look for other BSSs
C. How often a STA in power save mode wakes up to listen to Beacon frames
D. How long a STA performing active scanning will listen for Probe Responses before changing channels

正解：C

解説：
Explanation
The value of the Listen Interval field in an Association Request frame indicates how often a STA in power save mode wakes up to listen to Beacon frames. The Listen Interval is expressed in units of Beacon Intervals (typically 100 TU or 102.4 ms). For example, if the Listen Interval is set to 10, it means that the STA will wake up every 10 Beacon Intervals (or about 1 second) to check for buffered frames at the AP. The Listen Interval is used by the AP to determine how long it can hold frames for a STA in power save mode before discarding them .

質問 # 70
Which one of the following portions of information is communicated in the PHY Header?

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

正解：C

解説：
One of the information that is communicated by bits in the PHY header is data rate. Data rate is the speed at which data is transmitted or received over the wireless medium. Data rate depends on factors such as modulation, coding, channel width, spatial streams, and guard interval. Data rate is indicated by bits in different fields of the PHY header, depending on the type of PPDU (e.g., OFDM, HT, VHT, HE). The receiver uses these bits to determine how to decode and demodulate the rest of the PPDU. The other options are not correct, as they are not communicated by bits in the PHY header. SNR (Signal-to-Noise Ratio), noise, and signal strength are measured by the receiver based on its own capabilities and environment.

質問 # 71
When a data frame is encrypted with WPA2, to which portion of the frame is the encryption applied?

A. The whole MPDU
B. Frame body and MAC Header
C. Frame body excluding the LLCPDU
D. Frame body including the LLCPDU

正解：D

解説：
Explanation
When a data frame is encrypted with WPA2, the encryption is applied to the frame body including the LLCPDU. The LLCPDU (Logical Link Control Protocol Data Unit) is a part of the frame body that contains information such as protocol type, source and destination service access points (SAPs), and control fields. The LLCPDU is added by the LLC (Logical Link Control) sublayer to provide multiplexing and flow control functions for different upper layer protocols. When a data frame is encrypted with WPA2, which uses AES-CCMP as its encryption algorithm, both the payload and the LLCPDU are encrypted as a single unit. The MAC header and FCS are not encrypted, as they are needed for addressing and error detection purposes.

質問 # 72
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?

A. Authentication
B. 4-Way Handshake
C. Reassociation
D. Probe Response

正解：B

解説：
The 4-way handshake is the process that establishes the pairwise transient key (PTK) between the client and the AP in WPA2-PSK. The PTK is derived from the PSK, the SSID, and some random numbers exchanged in the handshake frames. The PTK is used to encrypt and decrypt the data frames between the client and the AP. Therefore, in order to decrypt WPA2-PSK data packets, a protocol analyzer needs to capture the 4-way handshake frames and have the PSK and SSID configured in the analyzer software.

質問 # 73
802.11k Neighbor Requests and Neighbor Reports are sent in what type of Management Frames?

A. Reassociation Request and Reassociation Response
B. Beacon
C. RRM
D. Action

正解：D

解説：
Explanation
802.11k Neighbor Requests and Neighbor Reports are sent in Action frames. An Action frame is a Management frame that is used to perform various operations or functions related to the operation or maintenance of a wireless network. An Action frame consists of a Category field that indicates the type of action being performed, and a variable-length Action Details field that contains specific information related to the action. For example, an Action frame with a Category field value of 5 indicates a Radio Measurement action, and the Action Details field may contain a Neighbor Request or a Neighbor Report subelement .
