CWNP CWAP-404 Exam Syllabus Topics:

Topic	Details
Topic 1	Protocol Analysis: The topic in the CWNP CWAP-404 exam evaluates the skill of a wireless network professional to capture and analyze 802.11 frames effectively. Candidates must demonstrate proficiency in configuring protocol analysis tools, interpreting frame captures to diagnose issues, and applying appropriate troubleshooting methods.
Topic 2	Spectrum Analysis: The topic assesses the ability of a wireless network professional to capture and interpret RF spectrum data. The exam targets the skills in identifying device signatures and RF issues through spectrum analyzers.
Topic 3	WLAN Medium Access: The exam evaluates the understanding of a wireless network professional about 802.11 contention algorithms and their impact on WLAN performance. The CWAP-404 Exam requires candidates to analyze QoS configurations and operations.
Topic 4	PHY Layers and Technologies: In the topic, the CWAP-404 exam tests the understanding of a wireless network professional about the Physical (PHY) layer functions and technologies. Wireless analysts need to describe and apply knowledge of PHY headers, PPDUs, and other PHY-related data. This topic ensures that analysts are proficient in interpreting PHY information within protocol analyzers and can select appropriate capture devices for different PHY types.
Topic 5	Frame Exchanges: The topic evaluates the skills of a wireless network professional in capturing, understanding, and analyzing various frame exchanges, including BSS discovery, joining, roaming, and data frames. The CWAP-404 exam targets the ability of candidates to troubleshoot and resolve issues related to MAC layer operations, ensuring they can maintain robust and efficient WLAN communications.

CWNP Certified Wireless Analysis Professional Sample Questions (Q83-Q88):

NEW QUESTION # 83
When performing protocol analysis, you capture an 802.1 lac data frame on channel 52, transmitted at MCS 8.
At what data rate was the PHY Preamble transmitted?

A. 86.7 Mbps
B. 6 Mbps
C. 54 Mbps
D. 78 Mbps

Answer: B

Explanation:
Explanation
The data rate at which the PHY preamble was transmitted is 6 Mbps. The PHY preamble is a part of the PPDU that is transmitted before the PHY header and the PSDU. The PHY preamble consists of a series of training fields that help the receiver to detect and synchronize with the signal. The PHY preamble is always transmitted at a fixed data rate that depends on the type of PPDU (e.g., OFDM, HT, VHT, HE). For an 802.1 lac data frame on channel 52, which uses VHT PPDUs, the data rate for the PHY preamble is 6 Mbps. This data rate does not depend on MCS (Modulation and Coding Scheme), which only affects the data rate for the PSDU.

NEW QUESTION # 84
Given: The exhibit shows a small network environment with dual-band APs.

What is true of the network shown in this spectrum analyzer trace?

A. There are two 40 MHz BSSs in this environment.
One AP has some 40 MHz traffic while the other AP has no client traffic.
B. There are at least three APs operating in this environment.
They are operating on channels 149, 153, and 161.
C. Only one AP in this network is configured to use the upper UNII band (UNII-3).
All other APs are in lower 5 GHz channels.
D. Two 802.11a APs are near the spectrum analyzer and are heavily utilized on channels 149 and
153.

Answer: A

NEW QUESTION # 85
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 including the LLC
D. Frame body excluding the LLC

Answer: C

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.

NEW QUESTION # 86
What must occur before an HT STA operating in an EDCA BSS can transmit a data frame over the wireless medium? (Choose 3)

A. The STA must receive a BlockAck, resetting the NAV to zero.
B. Its NAV must be equal to one.
C. The appropriate interframe space must expire.
D. Its CCA must report that the medium is idle.
E. The backoff timer for the AC must equal zero.
F. The AP must issue the STA a TXOP.

Answer: C,D,E

NEW QUESTION # 87
You are attempting to determine timing information within a packet capture of a WLAN protocol analyzer.
What time is used to display the time the packet was captured based on the system clock in the computer?

A. Interframe
B. Relative
C. Delta
D. Arrival

Answer: D
