CWNP Certified Wireless Analysis Professional Sample Questions (Q154-Q159):

NEW QUESTION # 154
Given: The Frame Check Sequence (FCS) is a 32 CRC used for error detection. The CRC is calculated over what?

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

Answer: C

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 # 155
Which one of the statements regarding the Frame Control field in an 802.11 MAC header is true?

A. The Frame Control field is always set to 0
B. Only Control frames have a Frame Control field
C. The Frame Control field is used to communicate the duration value
D. The Frame Control field contains three sub-fields and eight one-bit flags

Answer: D

Explanation:
Explanation: The Frame Control field in the 802.11 MAC header contains several sub-fields that define control information about the frame, including the type of frame, whether the frame is fragmented, and other parameters. Specifically, the Frame Control field has two main parts:
The sub-fields include Protocol Version, Type, Subtype, etc.
It also contains eight one-bit flags such as To DS, From DS, More Fragments, Retry, Power Management, etc.

NEW QUESTION # 156
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 # 157
Which one of the following statements describes the function of WMM Admission Control?

A. APs regulate the available bandwidth in an attempt to provide a guarantee of the amount of time that a STA has available to access the channel
B. APs control access to the wireless medium by polling STAs for data packets
C. APs guarantee Voice and Video access categories priority over the WLAN medium
D. Provides a new 802.11 Authentication method for Voice devices

Answer: C

NEW QUESTION # 158
The network administrator at ABC Engineering has taken a large packet capture from one of their APs running in monitor mode. She has very little knowledge of 802.11 protocols but would like to use the capture file to evaluate the overall health and performance of their wireless network.
When she asks your advice, which tool do you recommend she opens the packet capture file with?

A. WLAN scanner
B. Capture visualization tool
C. Spectrum analyzer
D. Python

Answer: B

Explanation:
A capture visualization tool is a software application that can open a packet capture file and display various graphs, charts, tables, and statistics that illustrate the characteristics and behavior of the wireless network. A capture visualization tool can help a network administrator with little knowledge of 802.11 protocols to evaluate the overall health and performance of their wireless network by providing a visual and intuitive representation of the captured data. A spectrum analyzer is a hardware device that measures the radio frequency signals in a given frequency range and displays their amplitude, frequency, and modulation. A spectrum analyzer can help identify sources of interference and noise in the wireless environment, but it cannot open a packet capture file. Python is a programming language that can be used to write scripts or applications that manipulate or analyze packet capture files, but it requires coding skills and knowledge of
802.11 protocols. A WLAN scanner is a software application that scans for available wireless networks and displays information such as SSID, BSSID, channel, signal strength, security type, and vendor. A WLAN scanner can help discover wireless networks and their basic parameters, but it cannot open a packet capture file.
