CWNP CWDP-304 Online Questions & Answers

• Question 161:

  A customer is acquiring a new VoWLAN system to replace their existing wired phone system. When reading about his system's requirements, you learned that is requires 25 db of SNR to work as expected. After surveying the environment, you discovered that the noise floor is -88 dBm. What should be the minimum RSSI value to meet the system's requirements?

  A. -70 dBm
  B. -67 dBm
  C. -65 dBm
  D. -63 dBm
  D. -63 dBm

• Question 162:

  During a validation site survey, you realize that the installers mounted some of the APs above the ceiling. They said that this was a request from the building architect due to aesthetics constraints.

  During the requirements gathering, you weren't advised about any aesthetics constraints from the main stakeholder of the project. What should you do in this case?

  Response:

  A. Remove all external antennas and use only the internal antennas to reduce multipath.
  B. Advise the stakeholder that WLAN performance requirements will not be met and a new design process will be needed to meet the requirements.
  C. Leave it as it is and allow automatic channel management to correct any issues.
  D. Increase the output power on all APs by 6 dB immediately.
  B. Advise the stakeholder that WLAN performance requirements will not be met and a new design process will be needed to meet the requirements.

• Question 163:

  Which operational plane would be responsible for performing automated RF management? Response:

  A. Integration
  B. Data
  C. Distribution
  D. Control
  E. Management
  D. Control

• Question 164:

  When performing a roaming test and packet capture at the same time, what are two particular frames that will be present when roaming between two APs is successful?

  A. Beacon and DTIM
  B. Probe Request and Probe Response
  C. Association Request and Association Response
  D. Reassociation Request and Reassociation Response
  D. Reassociation Request and Reassociation Response

• Question 165:

  What kind of antenna results in a nearly circular pattern on the azimuth chart but a very flat donut shape on the elevation chart?

  A. High gain omni-directional
  B. 20 degree vertical yagi
  C. 120 degree horizontal sector
  D. 60 degree horizontal patch
  B. 20 degree vertical yagi

• Question 166:

  As you plan a WLAN upgrade, you have assessed the network requirements and data signatures of your applications. One of the popular applications used on your network requires high bandwidth and low to medium Wi-Fi loss, but can tolerate moderate latency and jitter.

  What application matches this description?

  A. Voice
  B. Email
  C. Skype chat
  D. Video-on-demand
  B. Email

• Question 167:

  You are being asked to design a WLAN for a number of WLAN clients that will use Telnet as the primary application. The customer has asked that you use only the number of APs necessary because of the complex installation and

  construction costs each AP installation will incur in this particular environment.

  What design factors do you consider?

  Response:

  A. Omnidirectional antennas should be used to maximize cell overlap.
  B. Use 11 Mbps as the lowest basic rate.
  C. Clients could benefit from RTS/CTS mode for all transmissions.
  D. AP transmit power should be turned down to minimize co-channel interference.
  C. Clients could benefit from RTS/CTS mode for all transmissions.

• Question 168:

  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 11
  D. Leave it as it is; sometimes using all 11 channels in 2.4 GHz gives the optimum performance result
  C. Reconfigure the automatic channel assignment settings to use only channels 1, 6, and 11

• Question 169:

  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
  B. Router

• Question 170:

  When analyzing published competitive tests by equipment vendors, what items are the tests usually lacking? (Choose all that apply.) Response:

  A. Client devices and configurations
  B. Audit by a third party
  C. Detailed test methodology
  D. Detailed configurations of each vendor's equipment
  A. Client devices and configurations
  C. Detailed test methodology
  D. Detailed configurations of each vendor's equipment
