CWNP PW0-250 Online Questions & Answers

• Question 31:

  Given: A WLAN controller is connected to ABC Company's core layer 3 Ethernet switch with an IEEE 802.1Q trunk connection. The WLAN controller's native VLAN is VLAN 6 and its IP address is 10.0.14.2 /24. Lightweight APs supporting centralized forwarding are connected to the network on VLANs 7, 8, and 9, and they each build a layer 3 tunnel back to the WLAN controller's IP address. The dynamically assigned IP addresses received by each AP from a DHCP server will be .

  A. Associated with the VLAN on which they are connected.
  B. Associated with the native VLAN of the WLAN controller.
  C. Associated with VLAN 1, the default VLAN for new APs
  D. Associated with a non-routable VLAN until the MAC address of the AP is removed from the controller's MAC filter
  A. Associated with the VLAN on which they are connected.

• Question 32:

  The exhibit illustrates the azimuth and elevation for what type of antenna?

  

  A. Omni-directional
  B. 20 degree vertical yagi
  C. 120 degree horizontal sector
  D. 60 degree horizontal patch
  E. 10 degree vertical grid
  C. 120 degree horizontal sector

• Question 33:

  What are some advantages of designing guest access as it is shown in the exhibit?

  

  A. Allows a single SSID with different authentication/encryption models to be used for all WLAN services for corporate users and guests
  B. Minimizes configuration requirements for segmentation and filtering of guest traffic across internal LAN
  C. The border firewall configuration will not require any additional rules to pass guest traffic to the DMZ controller
  D. Enhances performance of web proxy servers in the DMZ for guest Internet traffic
  E. Allows simple and secure guest collaboration (file/print sharing) with corporate users
  B. Minimizes configuration requirements for segmentation and filtering of guest traffic across internal LAN

• Question 34:

  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.
  E. With properly formatted .bmp and .png graphics, the site survey software should be able to extract the scale directly from the graphic data during import.
  C. Use the longest available measurement (like a straight exterior wall) to calibrate the graphic's scale.

• Question 35:

  Assume that your network operates in a regulatory domain that allows use of UNII-1, UNII-2, UNII- 2e, UNII-3, and the 5.8 GHz ISM band for indoor Wi-Fi. In your upcoming 802.11n deployment, you would like to take advantage of the performance improvements that result from channel bonding. However, after extensive testing, you have determined that your mission-critical WLAN should not use channels requiring DFS support.

  Given those two criteria (enable channel bonding and disable DFS channels), in the 5 GHz spectrum, how many non-overlapping channels will your system be able to use?

  A. 2
  B. 3
  C. 4
  D. 6
  E. 11
  C. 4

• Question 36:

  Given: Use Exhibit 1, 2, and 3 to answer the question.

  

  

  The azimuth and elevation charts for which type of antenna are shown in Exhibit 1?

  A. Figure 1
  B. Figure 2
  C. Figure 3
  D. Figure 4
  E. Figure 5
  F. Figure 6
  C. Figure 3

• Question 37:

  During a post-deployment verification, you are requested to troubleshoot an area where users are experiencing poor throughput. They are using data communication only, mainly from laptops. You captured the frame displayed in the exhibit from the location where problems are reported. This frame is typical of those that were captured by the analyzer.

  

  What does this frame reveal about the RF network in this area?

  A. One station seems to be streaming video, thus may have reserved significant bandwidth via admission control
  B. Contention Free is in place in this network, which may starve some non-QoS stations from access
  C. Multipath or excessive collisions seem to be an issue in this area
  D. The AP seems to be too far to provide enough coverage to this area
  E. Stations are using null data frames as protection mechanisms to reserve the medium
  F. The station that sent this frame is causing a DoS attack by using extended Duration values
  C. Multipath or excessive collisions seem to be an issue in this area

• Question 38:

  What antenna connector type is displayed in the exhibit?

  

  A. RP-TNC
  B. RP-SMA
  C. N Connector
  D. MC Connector
  E. MMCX
  B. RP-SMA

  A. Channels supported by infrastructure
  B. Key caching protocols
  C. Cipher suite
  D. PHY standard used by client
  E. Supported uplink and downlink MCS rates
  F. The infrastructure's roaming algorithm
  G. Channels supported and scanned by client
  A. Channels supported by infrastructure
  B. Key caching protocols
  G. Channels supported and scanned by client
