CWNP Certified Wireless Analysis Professional Sample Questions (Q75-Q80):

NEW QUESTION # 75
Which one of the following portions of information is communicated in the PHY Header?

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

Answer: B

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 # 76
An HT STA does not receive an ACK for a first-attempt data frame that it transmitted. Assuming this STA is not using BlockAcks in this case, what happens to the HT STA's EDCA contention window?

  • A. It varies because the backoff algorithm is random.
  • B. The contention window is not affected by failed Data frame delivery.
  • C. The contention window approximately doubles in size.
  • D. The slot time within the contention window decreases by 50%.
  • E. The contention window is immediately closed, and the frame is retransmitted.

Answer: C


NEW QUESTION # 77
In which element of a Beacon frame would you look to identity the current HT protection mode in which an AP is operating?

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

Answer: B

Explanation:
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.

NEW QUESTION # 78
What types of wireless systems are illustrated?

  • A. An 802.11 HR/DSSS system using channel 2 and a digital FHSS phone
  • B. A Bluetooth v2.0 file transfer and a 40 MHz HT AP on channels 11, 7 (primary, secondary)
  • 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 # 79
The 802.11r-2008 amendment to the 802.11 specification introduces what new Information Elements (IEs) to facilitate fast BSS transitions? (Choose 2)

  • A. HT IE (High Throughput)
  • B. DS IE (Distribution System)
  • C. FT IE (Fast Transition)
  • D. FSR IE (Fast Secure Roaming)
  • E. RSN IE (Robust Security Network)
  • F. MD IE (Mobility Domain)

Answer: C,F
