CWNP CWNP Wireless LAN Certifications PW0-105 Questions & Answers

• Question 121:

  What feature(s) are most likely to be supported by 802.11 enterprise-class WLAN controllers? (Choose 4)

  A. Link aggregation / port trunking

  B. 802.1p and DSCP QoS

  C. BGP and Frame Relay

  D. Captive web portals

  E. IGMP snooping

  Correct Answer: ABDE

• Question 122:

  Given: You are the network administrator for ABC Company. Your manager has recently attended a wireless security seminar. The seminar speaker taught that a wireless network could be hidden from potential intruders if you disabled the broadcasting of the SSID in Beacons and configured the access points not to respond to Probe Request frames that have a null SSID field.

  Your manager suggests implementing these security practices. What response should you give to this suggestion? (Choose two)

  A. Any 802.11 protocol analyzer can see the SSID in clear text in frames other than Beacons and Probe Response frames. This negates any security benefit of trying to hide the SSID in Beacons and Probe Response frames.

  B. This security practice prevents manufacturers' client utilities from detecting the SSID. As a result, the SSID cannot be obtained by attackers, except through social engineering, guessing, or use of a WIPS.

  C. Although it does not benefit the security posture, hiding the SSID in Beacons and Probe Response frames can be helpful for preventing some users (such as guests) from attempting to connect to the corporate network.

  D. Any tenants in the same building using advanced penetration testing tools will be able to obtain the SSID by exploiting WPA EAPOL-Key exchanges. This poses an additional risk of exposing the WPA key.

  E. To improve security by hiding the SSID, the AP and client stations must both be configured to remove the SSID from association request and response frames. Most WLAN products support this.

  Correct Answer: AC

• Question 123:

  What component of the 802.11 standard allows stations to reserve access to the RF medium for a specified period of time?

  A. Long slot times

  B. DTIM Interval

  C. Listen Interval

  D. Probe Request frames

  E. RTS or CTS frames

  Correct Answer: E

• Question 124:

  Given: Network users and IT personnel at a large machinery manufacturer have been discussing the potential uses and benefits of implementing an indoor WLAN. The network administrator and network manager have requested a meeting of senior management personnel to discuss a WLAN implementation before taking any site survey or implementation steps. The first order of discussion in the meeting is corporate policy concerning implementation and use of WLAN technology.

  What specific topics are appropriate in this policy meeting? (Choose two) A. Vendor hardware recommendations

  B. Business justification

  C. User productivity impact

  D. Antenna types

  E. Obtaining permits and zoning requirements

  Correct Answer: BC

• Question 125:

  Given: Your consulting firm has recently been hired to complete a site survey for ABC Company. Your engineers use predictive modeling software for surveying, but ABC Company insists on a pre- deployment site visit.

  What tasks should be performed as part of the pre-deployment visit to prepare for a predictive survey? (Choose two)

  A. With a spectrum analyzer, identify the type, amplitude, and location of RF interference sources, if any are present.

  B. Evaluate the building materials at ABC's facility and confirm that the floor plan documents are consistent with the actual building.

  C. Validate that the AP transmit power and antenna type is identical for each AP in ABC's existing deployment.

  D. Collect information about ABC Company's security requirements and the current configuration of their RADIUS and user database servers.

  E. Simultaneously capture and analyze data on each 802.11 channel to establish a baseline for potential network capacity and throughput.

  Correct Answer: AB
