CWNP CWDP-305 Online Questions & Answers

• Question 161:

  The thermal noise is at 174 dBm/Hz. A spectrum analyzer has a resolution bandwidth of 1 kHz and a 5 dB noise figure. What is the level of the noise floor? Response:

  A. 174 dBm
  B. 139 dBm
  C. 144 dBm
  D. 204 dBm
  B. 139 dBm

• Question 162:

  After designing and deploying a WLAN infrastructure, you notice that co-channel interference (CCI) is causing poor performance in the 2.4 GHz band. Although the WLAN was primarily designed for 5 GHz, 2.4 GHz was included as a best-effort solution. You discover that the implementers did not follow your configuration guidelines. What can you do to minimize the impact of CCI in the 2.4 GHz band without adding adjacent-channel interference (ACI)?

  A. Add more APs to the infrastructure
  B. Increase the transmit power on all APs
  C. Turn off 2.4 GHz radios on some APs
  D. Use all channels available in the 2.4 GHz band
  C. Turn off 2.4 GHz radios on some APs

• Question 163:

  How can you increase efficiency in an 802 11n 2.4 GHz multiple-channel architecture network?

  A. Disable 802 11b data rates
  B. Use channels 1,3, 5, 7, 9, and 11
  C. Use only channels 1 and 2
  D. Use 40 MHz channels
  A. Disable 802 11b data rates

• Question 164:

  NicoCo is building a new facility and would like to install a WLAN for primary connectivity of all clients. The requirements are dual-spectrum 802.11n supporting voice and location tracking.

  What type of pre-deployment survey should be performed?

  Response:

  A. Passive, using optimized channels
  B. Active, using a voice handset
  C. Active, using a lowest common denominator client
  D. Predictive
  E. Passive, all channels
  D. Predictive

• Question 165:

  You are on site, planning a network at a freight shipping company on a busy harbor. Since the preliminary WLAN design specifies support for the 5 GHz spectrum, you would like to test for radar pulses to determine if DFS channels should be supported at this facility. As a part of your spectral survey with a laptop-based analyzer, you include DFS testing to identify the presence of radar. This is done by manually observing Real-time FFT, Duty Cycle, and Active Devices charts of the spectrum analyzer software.

  What potential drawback is present with this DFS test method?

  A. Many WLAN products that support DFS channels report several false positives. Ideally, the actual WLAN equipment used in the deployment should be used to test for DFS.
  B. Some sources of 5 GHz radar, such as military ships, are mobile in nature. A longer, automated test setup should be used to identify the presence or absence of radar.
  C. Manual identification of radar pulses using spectrum analysis charts can be very difficult due to radar's low amplitude at the Wi-Fi receiver.
  D. Modern spectrum analyzer adapters do not provide the necessary bandwidth resolution required to detect and measure radar signatures.
  C. Manual identification of radar pulses using spectrum analysis charts can be very difficult due to radar's low amplitude at the Wi-Fi receiver.

• Question 166:

  When live video streaming solutions that transmit simultaneously to more than one recipient are used, what special capability should be considered and configured in all affected WLAN implementations?

  A. IPSec
  B. IPv6
  C. Multicasting
  D. Secure TCP
  C. Multicasting

• Question 167:

  Which of the following items could be considered constraints when performing a network design?(Choose all that apply.)

  A. Timeline
  B. Personnel
  C. Politics
  D. Budget
  A. Timeline
  B. Personnel
  C. Politics
  D. Budget

• Question 168:

  You performed a site survey with two USB Wi-Fi adapters using a special driver written for the site survey software. After deployment, you realized that the client devices used by your customer are getting lower RSSI values than that shown during your site survey. What is the most likely reason for this result?

  A. USB Wi-Fi adapters designed for site surveys may have better sensitivity than regular Wi-Fi cards installed in client devices.
  B. The transmit power on the APs is higher than needed.
  C. Regular Wi-Fi cards installed in client devices do not support the same protocols as survey adapters.
  D. USB Wi-Fi adapters have a greater sensitivity than internal Wi-Fi adapters.
  A. USB Wi-Fi adapters designed for site surveys may have better sensitivity than regular Wi-Fi cards installed in client devices.

• Question 169:

  What kind of applications has the character traits of many communications back and forth between the server and client for each transaction initiated by the user? For example, several files, images and other data files may be required to download to the client with each click from the user. Choose the best answer. Response:

  A. mobile apps
  B. console management interfaces
  C. high-data bandwidth application
  D. real-time application
  E. web-based application
  D. real-time application

• Question 170:

  A museum wants to offer Wi-Fi to its visitors. One of their requirements is to have the APs blend into the design of the museum. What should you do to meet this requirement?

  A. Use a plastic cover that could blend in with the environment
  B. Lock the AP inside of a metal box
  C. Place the APs in between walls and I-beams
  D. Use an 802.11b AP, so it looks old enough to be in a museum
  A. Use a plastic cover that could blend in with the environment
