CWNP CWAP-404 Exam Syllabus Topics:

Topic	Details
Topic 1	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 2	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.
Topic 3	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 4	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.

CWNP Certified Wireless Analysis Professional Sample Questions (Q131-Q136):

NEW QUESTION # 131
What should the To DS and From DS flags be to set to in an Association Response frame?

A. To DS = 0, From DS = 1
B. To DS - 0, From DS = 0
C. To DS - 1, From DS = 0
D. To DS = 1, From DS = 1

Answer: B

Explanation:
Explanation
The To DS and From DS flags should be set to 0 in an Association Response frame. An Association Response frame is a type of management frame that is transmitted by an AP to accept or reject an association request from a STA. The To DS (To Distribution System) and From DS (From Distribution System) flags are two bits in the Frame Control field of the MAC header that indicate whether a frame is destined for or originated from the DS (Distribution System), which is a system that connects multiple BSSs together. The To DS and From DS flags can have four possible combinations: 00, 01, 10, or 11. For an Association Response frame, which is sent from an AP to a STA within a BSS, both flags should be set to 0.

NEW QUESTION # 132
Given: There are many differences between analyzing wireless and wired networks. In a wireless network, there is no guarantee that one station can hear another station's transmissions.
If no corrective actions are taken nor corrective mechanisms implemented when a "hidden node" problem exists, which measurable statistics parameter will likely increase in a wireless protocol analyzer?

A. Duration value
B. Retransmission Count
C. BlockAck Reset
D. Contention Window
E. Authentication Failure
F. ACK Timeout

Answer: B

NEW QUESTION # 133
You suspect an interfere may exist in a BSS that is experiencing sporadic problems. You want to identify and locate the device. The actual device identify is not known.
What tool should be used for this purpose?

A. Spectrum analyzer
B. Throughput tester
C. Protocol analyzer
D. Cable tester

Answer: A

NEW QUESTION # 134
Which piece of information is not transmitted in an HT PPDU header?

A. Channel number
B. Number of Spatial Streams
C. PPDU length
D. MCS index

Answer: A

Explanation:
Explanation
The channel number is not transmitted in an HT PPDU header. An HT PPDU header is a part of the PPDU that contains information such as modulation, coding, data rate, and number of spatial streams for an 802.11n transmission. The channel number is not included in the HT PPDU header, as it is determined by the frequency band and channel width that are used by the transmitter and receiver. The channel number can be inferred from the frequency band and channel width, which are indicated by bits in different fields of the HT PPDU header, such as HT-SIG and HT-LTF. The other options are not correct, as they are transmitted in an HT PPDU header. The number of spatial streams, PPDU length, and MCS index are indicated by bits in the HT-SIG field of the HT PPDU header. References: [Wireless Analysis Professional Study Guide CWAP-404], Chapter 4: 802.11 Physical Layer, page 108-109

NEW QUESTION # 135
In which element of a Beacon frame would you look to identify the current HT protection mode in which an AP is operating?

A. HT Protection Element
B. HT Information Element
C. HT Operations Element
D. HT Capabilities Element

Answer: C

Explanation:
The HT protection mode in which an AP is operating can be identified by looking at the HT Operations element in a Beacon frame. The HT Operations element is a part of the Beacon frame that contains information about the High Throughput (HT) capabilities and operation of an
802.11n BSS. The HT Operations element has a field called HT Protection, which indicates how the BSS protects its HT transmissions from interference or collisions with non-HT devices or BSSs. The HT Protection field can have four values: No Protection, Nonmember Protection, 20 MHz Protection, or Non-HT Mixed Mode. The other options are not correct, as they do not contain information about the HT protection mode. The HT Protection element does not exist, the ERP Information element is used for Extended Rate PHY (ERP) protection mode for 802.11g devices, and the HT Capabilities element is used for indicating the supported HT features of an individual device.
