CWNP Certified Wireless Analysis Professional Sample Questions (Q101-Q106):

NEW QUESTION # 101
Given: The Frame Check Sequence (FCS) is a 32 CRC used for error detection.
The CRC is calculated over what?

A. PHY Header and Mac Header only
B. Mac Header and Frame Body only
C. PHY Header, MAC Header and Frame Body
D. Frame Body only

Answer: B

Explanation:
Explanation
The CRC is calculated over the MAC Header and Frame Body only. The CRC (Cyclic Redundancy Check) is a 32-bit value that is used for error detection in wireless transmissions. The CRC is calculated over the MAC Header and Frame Body of a PSDU, which are the parts of the data unit that contain information such as source and destination addresses, frame type, frame control, sequence number, payload, etc. The CRC is appended to the end of the PSDU as a FCS (Frame Check Sequence) field. The CRC is not calculated over the PHY Header or PHY Preamble, which are parts of the PPDU that contain information such as modulation, coding, data rate, etc. The PHY Header and PHY Preamble are added or removed by the PHY layer during the conversion between PSDU and PPDU.

NEW QUESTION # 102
In the analyzer trace shown, the TBTT is nominally 102.5 milliseconds.

Why does the Beacon transmission interval vary?

A. The access point must arbitrate to gain access to the RF medium in order to transmit a Beacon.
B. Beacon frames vary in size, and therefore some take slightly longer to send than others.
C. This trace shows an HT network where HR/DSSS nodes are active on the network. The access point is changing slot times from short to long as needed.
D. The DCF Interframe space (DIFS) is nominally 50 µs, but typically varies by as much as 10 µs, which causes delays in Beacons.

Answer: A

NEW QUESTION # 103
Which one of the following portions of information is communicated in the PHY Header?

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

Answer: A

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 # 104
What is the Extended IFS used in 802.11 contention?

A. When the lower data rates are used and you want the fastest medium access times
B. When 802.11ac must coexist with 802.11n
C. When a frame reception begins but the received frame is incomplete or corrupted based on the FCS
D. When the higher data rates are used and you want the fastest medium access times

Answer: B

NEW QUESTION # 105
With what access category's parameters are WLAN multicast video frames transmitted when the EDCAF is in use by the transmitting station?

A. AC_VO
B. AC_BE
C. AC_BK
D. AC_VI

Answer: B
