CWNP CWAP-404 Exam Syllabus Topics:

TopicDetails
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
  • 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
  • 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 (Q70-Q75):

NEW QUESTION # 70
You have been asked to recommend a solution for protocol capture of 802.11 frames consisting of 3x3:3 802.11ac communications. The requirement specifies that you gain a general view of a coverage area and does not require that you capture from specific user locations. The solution must be the least expensive practical solution possible that does not disrupt user access to the WLAN and it must be based on enterprise WLAN hardware.
What solution would you recommend so that any coverage area could be monitored on demand?

  • A. Install Wireshark on the Aps natively to allow dynamic capture while serving clients
  • B. Install laptop-based protocol analyzer near each AP
  • C. Install sufficient Aps so that an AP can be taken offline to perform protocol analysis as needed
  • D. Install the minimum number of Aps required for coverage and use these Aps for protocol analysis as needed

Answer: C


NEW QUESTION # 71
What IEEE 802.11 technology is illustrated by the exhibit?

  • A. U-APSD
  • B. TCP Fragment Bursting
  • C. Fragmentation
  • D. Jumbo frames
  • E. A-MSDU
  • F. A-MPDU

Answer: E


NEW QUESTION # 72
Which one of the following portions of information is communicated by bits in the PHY Header?

  • A. SNR
  • B. Noise
  • C. Signal strength
  • D. Data rate

Answer: D

Explanation:
Explanation
One of the information that is communicated by bits in the PHY header is data rate. Data rate is the speed at which data is transmitted or received over the wireless medium. Data rate depends on factors such as modulation, coding, channel width, spatial streams, and guard interval. Data rate is indicated by bits in different fields of the PHY header, depending on the type of PPDU (e.g., OFDM, HT, VHT, HE). The receiver uses these bits to determine how to decode and demodulate the rest of the PPDU. The other options are not correct, as they are not communicated by bits in the PHY header. SNR (Signal-to-Noise Ratio), noise, and signal strengthare measured by the receiver based on its own capabilities and environment.

NEW QUESTION # 73
What is the purpose of a PHY preamble?

  • A. It indicates to the PHY the modulation that shall be used for transmission (and reception) of the PSDU.
  • B. It communicates important information about the PSDU's length, rate, and upper layer protocol- related parameters.
  • C. It provides the receiver(s) with an opportunity for RF channel synchronization prior to the start of the PLCP header.
  • D. It provides a cyclic redundancy check (CRC) for the receiving station to validate that the PLCP header was received correctly.

Answer: C


NEW QUESTION # 74
As the WLAN engineer in your organization, you must troubleshoot performance problems related to co- channel interference (CCI).
What is a good measurement of CCI impact in addition to the number of APs seen on a channel?

  • A. Utilization
  • B. Non-Wi-Fi device count
  • C. The frequency used
  • D. Retries

Answer: C
