CWNP CWDP-304 Online Questions & Answers

• Question 101:

  You have been tasked with performing safety and operations training for outdoor bridge link installation. The antennas are to be installed on a 70-foot tower on one end and the roof top of an office building on the other end.

  What might be required for the tower installation?

  Response:

  A. Hiring a certified tower installer.
  B. Special antennas that avoid reflections on the tower poles.
  C. APs that are designed to operate above 70 feet.
  D. Special RF cables that will not create loss incurred by the metal tower construction.
  B. Special antennas that avoid reflections on the tower poles.

• Question 102:

  A WLAN that you designed has been deployed in one area, users ate complaining that the network performs poorly. When you analyze the area you see that a new interferer has been introduced that was not there during the pre-design survey You've been informed that the interferer cannot be removed as it is an essential loT device. What action do you recommend?

  A. Reconfigure the channel plan to work around the interferer
  B. increase the output power of the APs covering that area by at least 25 percent to overpower the interferer
  C. Place a metal enclosure around the interferer
  D. Use 40 MHz channels so that the devices can use either 20 MHz block depending on where the interferer operates
  A. Reconfigure the channel plan to work around the interferer

• Question 103:

  A signal passes through a 10-meter cable, an amplifier, and then a filter. The amplifier has an output that is eight times higher in power than its input. Each meter of cable reduces the signal level by a factor of 4. The filter has a loss of 5 dB.

  What is the total loss/gain of the three elements in series?

  Response:

  A. 65 dB loss
  B. 16 dB gain
  C. 56 dB loss
  D. 37 dB loss
  D. 37 dB loss

• Question 104:

  Modulation can be defined as: Response:

  A. The process of incorporating a chipping code to build resilience
  B. The process of encoding data symbols using a carrier frequency
  C. The process of modifying a carrier signal to represent data
  D. The process of representing data using RF coding
  C. The process of modifying a carrier signal to represent data

• Question 105:

  Before connecting, mounting and powering 213 total controller-based APs what action should be taken to ensure that they are configured by the controller once powered on and connected lo the network''

  A. Configure profiles in the controller and assign them to the APs
  B. Configure the controller to provide PoE to the APs
  C. Configure the network to allow the APs to have direct Internet access immediately
  D. Ensure mat TLS tunnels will work between the APs and the controller
  A. Configure profiles in the controller and assign them to the APs

• Question 106:

  When troubleshooting coverage issues for a wireless network as it appears to new client associations, you should perform which type of survey? Response:

  A. Active survey
  B. Passive survey
  C. A survey is not necessary.
  D. Predictive survey
  B. Passive survey

• Question 107:

  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 108:

  As an implementation engineer, you have just received initial design specs from a network designer for your dual-band 802.11n deployment. The network design documents prescribe the following data rate configuration for the 2.4 GHz radio:

  Basic Rates 5.5, 6, 11, 12 Mbps Supported Rates 9, 18, 24, 36, 48, and 54 Mbps as well as MCS 0-15 What will result from this design strategy?

  A. By disabling support for 1 and 2 Mbps while allowing 5.5 and 11 Mbps, the network will force 802.11b clients to use these higher data rates.
  B. Protection mechanisms will always be in use on this network to support 5.5 and 11 Mbps as basic rates.
  C. HR/DSSS (802.11b) stations will not be able to associate to the service set.
  D. This configuration violates the IEEE specification that defines 6, 12, and 24 Mbps as mandatory data rates for 802.11g/n.
  A. By disabling support for 1 and 2 Mbps while allowing 5.5 and 11 Mbps, the network will force 802.11b clients to use these higher data rates.

• Question 109:

  What limitation exists when WMM is not enabled on an 802.11n WLAN?

  A. 802.11 QoS will not be available
  B. The maximum channel-width will be 20MHz
  C. EDCA values will change
  D. Only two ACs will be available
  A. 802.11 QoS will not be available

• Question 110:

  An AP vendor being considered for a WLAN deployment suggests that their 2 4 GHz and 5 GHz dual-band APs use software defined radios What unique capability does this indicate in comparison to non-software defined radios?

  A. At least one radio can be configured for either 2 4 GHz or 5 GHz operations
  B. The radios can have their SSlDs configured through software
  C. Software is used to configure the encryption settings
  D. Software is used to configure the entire WLAN profile
  A. At least one radio can be configured for either 2 4 GHz or 5 GHz operations
