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

NEW QUESTION # 75
You are troubleshooting a client that is experiencing slow WLAN performance. As part of the troubleshooting activity, you start a packet capture on your laptop close to the client device. While analyzing the packets, you suspect that you have not captured all packets transmitted by the client. By analyzing the trace file, how can you confirm if you have missing packets?

A. Retransmission are an indication of missing packets
B. Protocol Analyzers show the number of missing packets in their statistics view
C. Look for gaps in the sequence number in MAC headers
D. The missing packets will be shown as CRC errored packets

Answer: C

Explanation:
Each 802.11 data frame includes a sequence number in the MAC header that increments for successive frames within a traffic stream. If sequence numbers are not consecutive and there are gaps without corresponding retransmissions, this indicates that some frames were transmitted but not captured by the analyzer, confirming missing packets in the trace.

NEW QUESTION # 76
Finish the statement:
It is possible to distinguish between_______22 MHz transmissions and________20 MHz transmissions when looking at an FFT plot.

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

Answer: D

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 # 77
You are using a protocol analyzer to troubleshoot a network and you notice a client frequently sending QoS Null Function frames. What do you conclude?

A. This is normal behavior; these frames are part of the WMM implementation to ensure Quality or Service and are called announcement frames
B. This is normal behavior, these frames are used to flip the Power Management bit in the Frame Control field and are called trigger frames
C. This is not normal behavior; the client is misbehaving and consuming valuable airtime
D. This is normal behavior, these frames are part of the sounding exchanging used for Transmit Beamforming and are called PS-Poll frames

Answer: B

Explanation:
QoS Null Function frames are used by a client to indicate a change in its Power Management status without carrying data. They are normal in WMM Power Save operations, allowing the client to enter or exit power-save mode efficiently.

NEW QUESTION # 78
How many frames make up the Group Key Handshake excluding any Ack frames that may be required?

A. 0
B. 1
C. 2
D. 3

Answer: B

Explanation:
The Group Key Handshake consists of two EAPOL-Key frames exchanged between the AP and the client. The AP sends a message containing the new Group Temporal Key, and the client responds with a confirmation message indicating successful installation of the key.

NEW QUESTION # 79
Which statement is true regarding the Association Identifier (AID) used in IEEE 802.11 WLANs?

A. The AID is used by the access point in EDCA mode to reduce duplicate transmissions when sending multicasts.
B. The AID has a maximum value of 2007, and resides in the duration/ID field of a PS-Poll frame.
C. The AID field is present only in Beacons frames.
D. The AID has a maximum value of 2048, and is used to uniquely identify a wireless client station associated with an access point.
E. The client station is assigned an AID value in the 802.11 authentication response frame.

Answer: B
