CWNP PW0-105 Online Questions & Answers

• Question 61:

  Given:

  XYZ Company is planning to install a new 802.11 WLAN, but wants to upgrade its wired infrastructure first to provide the best user experience possible. XYZ has hired you to perform the RF site survey. During the interview with the network

  manager, you are told that the new Ethernet edge switches will support VoIP phones and 802.11 access points, both using 802.3af PoE.

  After hearing this information, what immediate concerns do you note?

  A. VoIP phones and 802.11 access points should not be powered by the same edge switch due to distortion.
  B. The edge Ethernet switches will need to support 802.3at PoE in order to support both access points and VoIP phones.
  C. If the switches are in optimal locations for VoIP phones, they are likely to be suboptimal locations for 802.11 APs.
  D. The power budget in the edge switches must be carefully planned and monitored based on the number of supported PoE devices.
  D. The power budget in the edge switches must be carefully planned and monitored based on the number of supported PoE devices.

• Question 62:

  A. Access points broadcast Beacons on all channels of each radio within the regulatory domain. Nearby client stations record information found in the Beacons for use in the association process.
  B. Client stations broadcast Probe Request frames on all supported channels in the regulatory domain. Nearby access points respond with Probe Response frames. Client stations record information in the Probe Response frames for use in the association process.
  C. Client stations broadcast Probe Request frames on the single channel for which they are programmed. Nearby access points respond on that channel with Probe Response frames. Clientstations record information found in the Probe Response frames for use in the association process.
  D. Access points broadcast Beacons on a single channel for which it is programmed. Nearby client stations listen for Beacon frames and record information found in the Beacons for use in the association process.
  D. Access points broadcast Beacons on a single channel for which it is programmed. Nearby client stations listen for Beacon frames and record information found in the Beacons for use in the association process.

• Question 63:

  A. The SSID is a security session identifier used in RSNs.
  B. The SSID must be included in an association request frame.
  C. The SSID is an alphanumeric value assigned to device manufacturers by the IEEE.
  D. The SSID is a pseudo-random number assigned to each client by an AP.
  E. The SSID is an alphanumeric value with a maximum length of 32 octets.
  F. When configuring a new network, creating an SSID is optional.
  B. The SSID must be included in an association request frame.
  E. The SSID is an alphanumeric value with a maximum length of 32 octets.

• Question 64:

  Given:

  ABC Company has hired you to perform an indoor site survey of their 7-story facility. ABC Company owns the building and rents out unused floors (floors 2 and 4) to other companies, and the other companies use 802.11 WLANs already.

  ABC Company wants all of the offices they occupy to be surveyed as part of the project.

  What actions should be recommended as part of the site survey project? (Choose two)

  A. Verify that RF signals from ABC's APs are not penetrating outside the perimeter of the building.
  B. Determine how much signal strength is bleeding between floors.
  C. Locate wiring closets on each floor occupied by ABC Company.
  D. Identify security best practice violations on neighboring WLANs.
  E. Verify that ABC's APs are not directly above or below APs on adjacent floors.
  B. Determine how much signal strength is bleeding between floors.
  C. Locate wiring closets on each floor occupied by ABC Company.

• Question 65:

  What is the intended use for the WLAN hardware shown in the exhibit?

  

  A. Mounting a lightning arrestor to a grounding rod
  B. Mounting an omnidirectional antenna to a mast
  C. Mounting an RF amplifier to a dipole antenna
  D. Mounting a PoE injector to a perforated radome
  E. Mounting an access point to a site survey tripod
  B. Mounting an omnidirectional antenna to a mast

• Question 66:

  What term correctly completes the following sentence?

  In an IEEE 802.11 frame, the IP packet is considered by the MAC layer to be a(n) _________.

  A. MAC Service Data Unit (MSDU)
  B. MAC Protocol Data Unit (MPDU)
  C. Bridge Protocol Data Unit (BPDU)
  D. PLCP Service Data Unit (PSDU)
  E. PLCP Protocol Data Unit (PPDU)
  A. MAC Service Data Unit (MSDU)

• Question 67:

  What are two channel modes specified by the 802.11n (High Throughput) PHY? (Choose two)

  A. 20 MHz
  B. 20/40 MHz
  C. 5/10 MHz
  D. 22 MHz
  E. 80 MHz
  F. 160 MHz
  A. 20 MHz
  B. 20/40 MHz

• Question 68:

  ABC Company has a 2.4 and 5 GHz WLAN deployment supporting four bands in the 5 GHz range (UNII 1, UNII 2, UNII 2e, and UNII 3). DFS functionality is enabled as required by the regulatory domain. Band steering is also enabled to encourage dual-band clients to use frequency bands with more capacity.

  Your performance analysis shows that many dual-band VoWiFi client devices will move back and forth between 2.4 and 5 GHz as the user roams throughout the building. All APs have 2.4 and 5 GHz radios enabled. This "band hopping" behavior is viewed by network staff to be undesirable. What is the most likely cause of the unpredictable client band selection behavior?

  A. Interference from 5 GHz radar sources has increased frame corruption and retries on channels 36-48 in UNII 1.
  B. 5 GHz frequencies offer better RF penetration than 2.4 GHz, but 2.4 GHz offers more voice call capacity and lower latency than 5 GHz.
  C. The voice client does not support DFS, and therefore experiences some 5 GHz coverage holes as it moves through the network.
  D. The client's band selection algorithm prefers 5 GHz, but band steering behavior usually steers 75- 85% of client devices to 2.4 GHz.
  C. The voice client does not support DFS, and therefore experiences some 5 GHz coverage holes as it moves through the network.

  A. Laptop-based Site Survey Utility - Creating a list of necessary APs and plotting their locations on a floor plan
  B. Wireless Network Management System - Managing multiple autonomous APs through the SNMP protocol
  C. 802.11 Protocol Analyzer - Capturing and decoding 802.11 frames for the purpose of troubleshooting and optimization
  D. Laptop-based Spectrum Analyzer - Monitoring the RF spectrum for interference sources and improper system operation
  E. WLAN Discovery Tool - Locating and identifying secured and unsecured WLAN access points
  F. Wireless Intrusion Protection System - Monitoring 802.11 frame exchanges for performance and security analysis and reporting
  E. WLAN Discovery Tool - Locating and identifying secured and unsecured WLAN access points
