CWNP CWAP-404 Exam Syllabus Topics:

Topic	Details
Topic 1	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 2	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 3	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 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	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 (Q88-Q93):

NEW QUESTION # 88

What frame is used for spectrum management, fast BSS transition and some other actions taken within a BSA?

A. Action
B. BlockAck
C. PS Poll

NEW QUESTION # 89
Which parameters accurately describe the Beacon Interval field in the Beacon frame? (Choose 2)

A. Indicates the desired time interval between TBTTs
B. Value can range from 0 to 2007
C. Measured in time units of 1024 ms
D. Indicates the exact time interval between Beacon transmissions
E. 4-octet length

Answer: A,C

NEW QUESTION # 90
When would you expect to see a Reassociation Request frame'

A. Every time a STA associates to an AP to which it has previously been associated
B. Only when a STA roams back to an AP it has previously been associated with
C. Every time a STA roams
D. Only when a STA is using FT roaming

Answer: C

Explanation:
Explanation
A Reassociation Request frame is sent every time a STA roams from one AP to another within the same ESS.
A Reassociation Request frame is similar to an Association Request frame, but it also contains the BSSID of the current AP that the STA is leaving. This allows the new AP to coordinate with the old AP and transfer the STA's context information, such as security keys, QoS parameters, and buffered frames. This way, the STA can maintain its connectivity and session continuity during roaming .

NEW QUESTION # 91
When a 5 GHz HT station in a 40 MHz BSS desires to protect a 40 MHz transmission from an OFDM station using an RTS/CTS or CTS-to-Self exchange, what frame format is used for the RTS and/or CTS frames?

A. Dual-CTS
B. HT-mixed format
C. Non-HT Duplicate
D. HT-greenfield format
E. Phased Coexistence PPDU

Answer: C

NEW QUESTION # 92
Which statements accurately describe IEEE 802.11 EDCA collision handling in a WMM-compliant infrastructure WLAN? (Choose 2)

A. After frames collide within a QoS STA and the lower priority AC subsequently gains a TXOP, the retry bit in the MAC header must be set to 1 to indicate a retry.
B. Collisions between contending EDCAFs within a QoS STA are resolved within the QoS STA
C. The WMM specification requires use of RTS/CTS as part of the EDCAF within each QoS STA to avoid internal collisions between ACs.
D. When frames collide within a QoS STA, data frames from lower priority ACs behave (as it relates to contention) as if there were an external collision on the wireless medium.
E. When a frame transmission on the wireless medium fails, the transmitter may not transmit another frame from any AC or to any destination until the frame experiencing a failure is successfully transmitted or the max retry count for that frame is reached.

Answer: B,D

NEW QUESTION # 93
