CWNP CWAP-404 Exam Syllabus Topics:

Topic	Details
Topic 1	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 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	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 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.

CWNP Certified Wireless Analysis Professional Sample Questions (Q87-Q92):

NEW QUESTION # 87
Which one of the following is not an 802.11 Management frame?

A. Authentication
B. Beacon
C. Action
D. PS-Poll

Answer: D

Explanation:
A PS-Poll (Power Save Poll) frame is not an 802.11 management frame. A PS-Poll frame is a type of control frame that is used by a STA in power save mode to request data frames from an AP. A STA in power save mode can conserve battery power by periodically sleeping and waking up. When a STA sleeps, it cannot receive any data frames from the AP, so it informs the AP of its power save status by setting a bit in its MAC header. The AP then buffers any data frames destined for the sleeping STA until it wakes up. When a STA wakes up, it sends a PS-Poll frame to the AP, indicating its association ID and requesting any buffered data frames. The AP then responds with one or more data frames, followed by an ACK or BA frame from the STA. The other options are not correct, as they are types of 802.11 management frames. An Action frame is used to perform various management actions, such as spectrum management, QoS management, radio measurement, etc. A Beacon frame is used to advertise the presence and capabilities of an AP or BSS. An Authentication frame is used to establish or terminate an authentication relationship between a STA and an AP.

NEW QUESTION # 88
What is used to respond with an uplink transmission to an MU-RTS trigger frame in the 802.11ax PHY?

A. HE MU PPDU
B. HE SU PPDU
C. VHT PPDU
D. HE TB PPDU

Answer: D

Explanation:
An HE TB PPDU (High Efficiency Trigger-Based Packet Data Unit) is used to respond with an uplink transmission to an MU-RTS trigger frame in the 802.11ax PHY (Physical Layer). An MU- RTS trigger frame is a frame that initiates a multi-user transmission opportunity (MU-TXOP) by requesting multiple stations (STAs) to send clear-to-send (CTS) frames on different spatial streams or resource units (RUs). An HE TB PPDU is a frame that contains data from multiple STAs that have been allocated RUs by an MU-RTS trigger frame or another type of trigger frame.
An HE SU PPDU (High Efficiency Single User Packet Data Unit) is a frame that contains data from a single STA using all available spatial streams or RUs. An HE MU PPDU (High Efficiency Multi User Packet Data Unit) is a frame that contains data from multiple STAs using different spatial streams or RUs without being triggered by another frame. A VHT PPDU (Very High Throughput Packet Data Unit) is a frame that uses the 802.11ac PHY and does not support multi- user transmissions.

NEW QUESTION # 89
You are troubleshooting throughput problems for a WLAN cell. The cell is provisioned with an
802.11ac dual-band AP. Users connected with both 5 GHz and 2.4 GHz connections are reporting performance problems. The AP settings are properly optimized. No interface issues have been detected (either co- channel interference or non-Wi-Fi interference) and the number of associated users is low.
What should you analyze to resolve the issue?

A. The 2.4 GHz radio configuration
B. The 5 GHz radio configuration
C. the Ethernet uplink and the network infrastructure
D. The antennas used on the client devices

Answer: C

NEW QUESTION # 90
According to 802.11-2007, in what frame type(s) might you find the PMK Count and PMKID List fields?

A. All frames that include the RSN IE
B. Only (Re)Association Request frames
C. Beacon and Probe Response frames
D. Authentication and Association Request and Response frames
E. EAPoL 4-Way Handshake frames

Answer: B

NEW QUESTION # 91
According to the 802.11n-2009 amendment, what security requirement is specified for HT BSSs?

A. In an RSN, HT stations may not communicate with one another using TKIP.
B. HT BSSs are prevented from supporting WEP.
C. All unicast traffic transmitted by an HT station and destined to an HT station must use AES- CCMP.
D. HT BSSs must mandatorily support 802.11r FT.
E. TKIP cannot be supported in an HT BSS.

Answer: A
