Success in the test of the Certified Wireless Analysis Professional (CWAP-404) certification proves your technical knowledge and skills. The CWAP-404 exam credential paves the way toward landing high-paying jobs or promotions in your organization. Many people who attempt the Certified Wireless Analysis Professional (CWAP-404) exam questions don't find updated practice questions. Due to this they don't prepare as per the current CWAP-404 examination content and fail the final test.

CWNP Certified Wireless Analysis Professional Sample Questions (Q68-Q73):

NEW QUESTION # 68
During a VHT Transmit Beamforming sounding exchange, the beamformee transmits a Compressed Beamforming frame to the beamformer. What is communicated within this Compressed Beamforming frame?

A. Beamformee Matrix
B. Feedback Matrix
C. Steering Matrix
D. Beamforming Matrix

Answer: B

Explanation:
The beamformee transmits a Feedback Matrix within the Compressed Beamforming frame to the beamformer. The Feedback Matrix contains information about the channel state between the beamformee and each spatial stream of the beamformer. This information is used by the beamformer to adjust its transmit weights and optimize its signal for the beamformee.

NEW QUESTION # 69
Which one of the best following is an advantage of using display filters instead of capture-time filters?

A. Multiple display filters can be applied simultaneously
B. Once created display filters are reusable for later captures
C. Display filters only hide the packets from view and the filtered packets can be enabled for view later
D. Display filters allow for focused analysis on just the packets of interest

Answer: D

Explanation:
display filters allow you to focus on things of interest and to ignore things you don't care about.

NEW QUESTION # 70
When an originator QoS STA initiates a BlockAck agreement with a recipient QoS STA, what is the first frame sent by the originator?

A. BlockAckReq
B. BlockAckSetupReq
C. ActionBAReq
D. BlockAckPolicyReq
E. ADDBA Request

Answer: E

NEW QUESTION # 71
You are analyzing a packet decode of a Probe Request and notice the SSID element has a length of zero. What do you conclude about the transmitting STA?

A. The STA is discovering a list of available BSSs
B. The STA's WLAN adaptor is disabled
C. The WLAN adaptor is configured in promiscuous mode
D. The STA is operating in Ad-Hoc mode

Answer: A

Explanation:
Explanation
The STA is discovering a list of available BSSs by sending a Probe Request with an empty SSID element.
This is also known as a broadcast Probe Request, as it does not specify any particular SSID to probe for. Any AP that receives this Probe Request will respond with a Probe Response containing its own SSID and other information about its BSS. This way, the STA can learn about all the BSSs in its vicinity and choose which one to associate with .

NEW QUESTION # 72
What is indicated to a QoS AP when a QoS STA sets U-APSD Flag bits to 1 in (Re) Association frames?

A. Which access categories are both trigger-enabled and delivery-enabled
B. Which access categories require admission control
C. Which access categories are scheduled
D. Which user priorities require use of a TSPEC
E. Which user priorities are mapped to access categories

Answer: A
