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

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.

Topic 3

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 4

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 5

MAC Sublayer and Functions: The topic measures the ability of a wireless network professional to understand and analyze the MAC layer operations. Candidates are expected to validate BSS configurations and identify issues like CRC errors and retransmissions, ensuring they can maintain the integrity and performance of the WLAN.

CWNP Certified Wireless Analysis Professional Sample Questions (Q86-Q91):

NEW QUESTION # 86
Why would a STA that supports 802.11k Radio Measurement send a Neighbor Request to an AP?

A. To request a list of neighboring APs which the STA can use as roaming candidates
B. To inform the current AP about the STA's intent to roam to a neighboring AP, ensuring a seamless handover
C. To learn about neighboring interference sources and tune its RF radio accordingly
D. To request a list of neighboring STAs which enables the STA to better pick the right protection mechanisms

Answer: A

Explanation:
A STA that supports 802.11k Radio Measurement would send a Neighbor Request to an AP to request a list of neighboring APs which the STA can use as roaming candidates. A Neighbor Request is an Action frame that contains a subelement specifying the type of information that the STA wants to receive from the AP. A Neighbor Report is an Action frame that contains a subelement with a list of neighboring APs that match the criteria specified in the Neighbor Request. The Neighbor Report provides information such as BSSID, channel, operating class, and PHY type of each neighboring AP. This information helps the STA to perform intelligent roaming decisions based on signal quality, load, and compatibility.

NEW QUESTION # 87
Where, in a protocol analyzer, would you find an indication that a frame was transmitted as part of an AMPDU?

A. A-MPDU flag in the HT Control Field
B. The Aggregation flag in the Radio Tap Header
C. A-MPDU flag in the Frame Control Field
D. The HT Operation Element

Answer: B

Explanation:
In a protocol analyzer, you would find an indication that a frame was transmitted as part of an A- MPDU by looking at the Aggregation flag in the Radio Tap Header. The Radio Tap Header is a pseudo- header that is added by some wireless capture devices to provide additional information about the physical layer characteristics of a frame. The Aggregation flag is one of the fields in this header, and it indicates whether the frame belongs to an A-MPDU or not. If the flag is set to 1, it means that the frame is part of an A-MPDU; if it is set to 0, it means that the frame is not part of an A-MPDU.

NEW QUESTION # 88
Which information elements (IE) are contained in an IEEE 802.11 Probe Request frame?
(Choose 2)

A. Status code
B. Supported rates
C. RSN IE
D. SSID
E. Association ID

Answer: B,D

NEW QUESTION # 89
In the 2.4 GHZ band, what data rate are Probe Requests usually sent at from an unassociated STA?

A. 1 Mbps
B. MCS 0
C. The minimum basic rate
D. 6 Mbps

Answer: C

Explanation:
Explanation
In the 2.4 GHz band, probe requests are usually sent at the minimum basic rate from an unassociated STA. A probe request is a type of management frame that is transmitted by a STA to discover available BSSs in its vicinity. A probe request can be sent on one or more channels in either passive or active scanning mode. In passive scanning mode, a STA listens for beacon frames from APs on each channel. In active scanning mode, a STA sends probe requests on each channel and waits for probe responses from APs. A probe request is usually sent at the minimum basic rate, which is the lowest data rate among the supported rates that is required for all STAs to join and communicate with a BSS. The minimum basic rate can vary depending on the configuration of each BSS, but it is typically one of these values: 1 Mbps, 2 Mbps, 5.5 Mbps, or 11 Mbps in the 2.4 GHz band. The other options are not correct, as they do not reflect how probe requests are usually sent in the 2.4 GHz band. MCS 0 is a modulation and coding scheme used by 802.11n/ac devices in either band, but it is not a data rate per se. 6 Mbps is a data rate used by OFDM devices in either band, but it is not usually configured as a minimum basic rate in the 2.4 GHz band.

A. Windows 8.1
B. Mac OS X
C. Windows 10
D. Windows 7

Answer: B
