CWNP CWAP-404 Exam Syllabus Topics:

TopicDetails
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
  • 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
  • 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 5
  • 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 (Q111-Q116):

NEW QUESTION # 111
What types of wireless systems are illustrated?

  • A. A Bluetooth v2.0 file transfer and a 40 MHz HT AP on channels 11, 7 (primary, secondary)
  • B. An 802.11 HR/DSSS system using channel 2 and a digital FHSS phone
  • C. An ERP IEEE 802.11 system using channel 6 and Bluetooth v1.2 discovery
  • D. A 2.4 GHz cordless phone on channel 14 and a wireless RFID reader

Answer: C


NEW QUESTION # 112
Finish the statement. It is possible to distinguish between _______and ______20 MHz transmissions when looking at an FFT plot.

  • A. OFDM and HT
  • B. ERP and VHT
  • C. HR/DSSS and ERP
  • D. HT and VHT

Answer: A

Explanation:
It is possible to distinguish between OFDM 20 MHz transmissions and HT 20 MHz transmissions when looking at an FFT plot. OFDM and HT are two different modulation schemes used by
802.11 WLANs. OFDM is used by legacy 802.11a/g devices, while HT is used by newer
802.11n/ac devices. OFDM and HT have different spectral characteristics that can be observed on an FFT plot. OFDM transmissions have a flat spectrum with sharp edges, while HT transmissions have a tapered spectrum with rounded edges. This is because HT uses guard intervals and cyclic prefixes to reduce inter-symbol interference and improve performance. The other options are not correct, as they do not describe different modulation schemes or channel widths that can be distinguished on an FFT plot.


NEW QUESTION # 113
Which one of the following is required for Wi-Fi integration in laptop-based Spectrum Analyzer software?

  • A. SNMP read credentials to the WLAN controller or APs
  • B. A supported WLAN adaptor with a customized driver
  • C. A dual radio spectrum analyzer card
  • D. Any 802.11 wireless adaptor

Answer: C


NEW QUESTION # 114
Which one of the following portions of information is communicated in the PHY Header?

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

Answer: C

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 strength are measured by the receiver based on its own capabilities and environment.


NEW QUESTION # 115
Which one of the following should be the first step when troubleshooting a WLAN issue?

  • A. Identify probable causes
  • B. Perform an initial WLAN scan and see if any obvious issues stand out
  • C. Define the problem
  • D. Identify capture locations

Answer: C

Explanation:
The first step in any troubleshooting process is to define the problem. This involves gathering information from various sources, such as users, network administrators, network documentation, and network monitoring tools. Defining the problem helps to narrow down the scope of the issue and identify the symptoms, causes, and effects of the problem.
