CWNP PW0-105 Online Questions & Answers

• Question 121:

  Given: ABC Hospital is planning a Wi-Fi infrastructure upgrade where the 802.11b/g APs would be replaced with new dual-radio HT (802.11n) APs. ABC wants to minimize the time and cost associated with performing a new site survey, so

  they will be mounting all of the new APs in the same locations and with the same cable drops as the existing APs.

  What is one performance drawback with this deployment method?

  A. Multipath will increase, causing excessive layer-2 retransmissions. The retransmissions will cause latency for VoWiFi handsets.
  B. Increased receiver sensitivity on the HT APs will cause them to continually change channels to avoid co-channel interference.
  C. If the existing UTP cabling is not Category 6 or better, the total Ethernet backhaul for each AP will be limited to 100 Mbps.
  D. In locations with line-of-sight to client devices and little multipath, the benefits of MIMO may be less significant than in other areas.
  D. In locations with line-of-sight to client devices and little multipath, the benefits of MIMO may be less significant than in other areas.

• Question 122:

  What information is transmitted in the Beacon management frames of an HT access point to communicate about backward compatibility with ERP and HR/DSSS stations? (Choose two)

  A. HT Protection mode
  B. NonERP Present field
  C. Secondary channel offset
  D. RIFS mode
  E. Power save mode of clients
  A. HT Protection mode
  B. NonERP Present field

• Question 123:

  Given: Joe runs a small hotel, and as a value added service for his customers he has implemented a Wi- Fi hot-spot. Joe has read news articles about how hackers wait at hot-spots trying to take advantage of unsuspecting users. Joe wants to avoid this problem at his hotel.

  What is an efficient and practical step that Joe can take to decrease the likelihood of active attacks on his customers' wireless computers?

  A. Implement Network Access Control (NAC) and require antivirus and firewall software along with OS patches
  B. Require EAP-FAST authentication and provide customers with a username/password on their receipt
  C. Implement an SSL VPN in the WLAN controller that initiates after HTTPS login
  D. Enable station-to-station traffic blocking by the access points in the hotel
  D. Enable station-to-station traffic blocking by the access points in the hotel

• Question 124:

  In a Wi-Fi client configuration utility, what feature is most likely to be user configurable?

  A. 802.1p to WMM mappings
  B. SNMPv3 Users
  C. WMM-PS Dozing Interval
  D. RADIUS Server IP Address
  E. EAP Authentication Type
  E. EAP Authentication Type

• Question 125:

  Given: When designing a WLAN infrastructure implementation for high client density at a public venue such as a conference or stadium, what are common best practices? (Choose 2)

  A. Use high-gain omnidirectional antennas to improve SNR
  B. Use directional antennas to isolate the RF propagation
  C. Configure APs to transmit at or near their maximum power setting
  D. Use WPA2-Personal security for ease of deployment
  E. Disable 802.11n MCS rates to prevent high overhead protection mechanisms
  F. Implement a band steering feature for dual-band clients
  B. Use directional antennas to isolate the RF propagation
  F. Implement a band steering feature for dual-band clients
