CWNP CWNP Certifications CWDP-304 Questions & Answers

• Question 111:

  Before performing a pre-deployment passive RF survey of a new deployment using survey mapping software, which of the following must be performed?

  Response:

  A. Determining AP transmit power

  B. Scaling the map

  C. Selecting antennas

  D. Checking client DTPC settings

  Correct Answer: B

• Question 112:

  When preparing a floor plan graphic for use in predictive and manual site surveying, what calibration method will lead to the most accurate and reliable RF data?

  A. Use the known size of a small object, such as a ceiling tile, and use a single instance of this object (e.g. a single ceiling tile) to scale the floor plan.

  B. Measure the width of an actual office doorway with a tape measure and use this value to calibrate against a doorway graphic.

  C. Use the longest available measurement (like a straight exterior wall) to calibrate the graphic's scale.

  D. Calibrate the ceiling height of the floor plan first, then the survey software should be able to auto-calibrate the X and Y planes of the graphic.

  Correct Answer: C

• Question 113:

  What metric implements the simplest algorithm and lowest accuracy in networks requiring locations?

  Response:

  A. Angle of Arrival (AoA)

  B. Time of Arrival (ToA)

  C. Time Difference of Arrival (TDoA)

  D. Received Signal Strength Indicator (RSSI)

  Correct Answer: D

• Question 114:

  While performing a validation site survey, you realize that overlapping channels are being used on the 2.4 GHz bad due to the automatic channel assignment algorithm of the WLAN infrastructure.

  What should you do to prevent this?

  A. Reconfigure the network to use static channel plans because automatic channel assignment algorithms are all broken

  B. Purchase and deploy new APs from a different vendor

  C. Reconfigure the automatic channel assignment settings to use only channels 1, 6, and

  D. Leave it as it is; sometimes using all 11 channels in 2.4 GHz gives the optimum performance result

  Correct Answer: C

• Question 115:

  What are methods of providing RF high availability?

  Response:

  A. Power APs to maximum power.

  B. Use the HSRP/VRRP protocol.

  C. Deploy using 100 percent overlap.

  D. Deploy 802.3af.

  E. Use dual spectrums.

  Correct Answer: C

• Question 116:

  If the amplifier in Question 4 has a noise figure of 10 dB but a gain of 0 dB, what is the total noise figure of the cable, amplifier, and filter in series?

  Response:

  A. 75 dB

  B. 16 dB

  C. 10 dB

  D. 70 dB

  Correct Answer: A

• Question 117:

  Your customer's 802.11n laptops are not able to see the SSID in the 5 GHz band in the conference room. When doing a walkthrough using one of these laptops, you confirm that it is unable to see the SSID in the 5 GHz band in the conference room. When using your own 802.11 ac laptop,

  you're able to see the SSID. What is the most likely cause of this problem?

  A. The AP is configured to use channel 36

  B. The customer laptop does not support Transmit Beamforming

  C. The AP is on channel 144

  D. Their laptops are SISO clients

  Correct Answer: C

• Question 118:

  An MSA commonly addresses at least which two legal categories?

  Response:

  A. Nondisclosure agreement

  B. Hold harmless

  C. Intellectual property protection

  D. Indemnity clause

  Correct Answer: A

• Question 119:

  A wireless network with fewer APs at higher power levels to cover a large area is said to be which of the following?

  Response:

  A. Capacity based

  B. Coverage based

  C. Destined for failure

  D. Ideal for roaming

  Correct Answer: B

• Question 120:

  A controller-based WLAN infrastructure has its controller on a different subnet than its APs.

  What device must be used to enable any communication between the Controller and the APs?

  A. NTP server

  B. Router

  C. PoE Layer 2 switch

  D. Wireless bridge

  Correct Answer: B
