CWNP CWDP-305 Online Questions & Answers

• Question 101:

  The installation crew for your WLAN project wants to install a few APs to locations nearby the ones specified in the RF design document. What next step should occur? Response:

  A. Confirm the mounting hardware.
  B. Choose a different AP model.
  C. Update the documentation.
  D. Consult the RF designer.
  D. Consult the RF designer.

• Question 102:

  Your customer requires a security solution where client credentials are used, not a Protected Access Credential (PAC), and the authentication server must have a certificate with optional client certificate use. Which EAP (Extensible Authentication Protocol) method is the best fit for these requirements?

  A. EAP-FAST
  B. EAP-TTLS
  C. EAP-TLS
  D. LEAP
  B. EAP-TTLS

• Question 103:

  What type of protection should be provided to outdoor antenna installations? Response:

  A. Static electricity
  B. Brownouts
  C. Lightning surge suppression
  D. A/C spikes
  C. Lightning surge suppression

• Question 104:

  You are using site software design features. You have imported a floor plan, but the simulated RF coverage is nowhere close to the real RF coverage you see with a walkabout.

  Given that the simulation is significantly different, when step was likely missed when using the software?

  Response:

  A. Conversion to DWG
  B. Conversion to PNG
  C. Adding extra APs to simulate interference
  D. Calibration
  D. Calibration

• Question 105:

  When performing a frame capture over the air during a voice call, you notice that frames in the downlink direction (from the AP to the client) are not being transmitted with the correct UP (User Priority) value for voice frames, but in the uplink direction (from the client to the AP), they are transmitted correctly. What is the likely cause of this issue?

  A. Bad client driver
  B. AP is not receiving enough PoE, thus not using QoS features
  C. Somewhere on the wired network QoS markings aren't being trusted
  D. Faulty antenna on the AP
  C. Somewhere on the wired network QoS markings aren't being trusted

• Question 106:

  Given: The 802.11ac APs you have selected for your public access deployment support many of the PHY and MAC enhancements offered by the 802.11n and 802.11ac amendments. The AP is configured for a single-band (2.4 GHz) and only allows 20 MHz channels. The WLAN radio in the AP is a 3x3 802.11n chip that supports two spatial streams.

  What is the maximum MCS rate that could be supported by this AP?

  A. 54 Mbps
  B. 65 Mbps
  C. 108 Mbps
  D. 144 Mbps
  D. 144 Mbps

• Question 107:

  When designing a wireless bridge to connect two offices 13 kilometers (approximately 8 miles) apart, which factor must the Wireless Engineer consider to account for Fresnel Zone clearance?

  A. Earth bulge
  B. Antenna gain
  C. FSPL
  D. Receive sensitivity
  A. Earth bulge

• Question 108:

  When surveying an existing WLAN infrastructure for a possible redesign, you use two Wi-Fi USB adapters to collect RSSI data and two USB spectrum analysis adapters to collect RF spectrum data. Since your laptop doesn't have enough USB ports, you use a 4-port powered USB 3.0 hub.

  What issues could be caused by the use of USB 3.0 that will impact your site survey?

  A. It does not give you enough bandwidth to collect data coming from all of the adapters.
  B. It does not give you enough power for all four of your adapters.
  C. It generates noise in the 2.4 GHz band, giving you a false perception of the noise floor.
  D. It generates noise in the 5 GHz band, giving you a false perception of the noise floor.
  C. It generates noise in the 2.4 GHz band, giving you a false perception of the noise floor.

• Question 109:

  Using a SCA means that all APs will be using the same channel in a given layer. How is the AP with which the client associates determined? Response:

  A. All APs share a virtual Multicast Address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.
  B. All APs share a virtual BSSID. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.
  C. All APs share a virtual IP address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.
  D. The client selects the AP based on a known set of MAC to BSSID mappings stored in the clients authorized SSID listing.
  D. The client selects the AP based on a known set of MAC to BSSID mappings stored in the clients authorized SSID listing.

• Question 110:

  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
