• Question 12:

  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.

  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.
  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.

• Question 13:

  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 14:

  Why is it recommended for a wireless network administrator to disable 1 Mbps and 2 Mbps data rates on the WLAN infrastructure? (Choose two) A. To improve capacity in the BSS

  B. To reduce the size of the AP's effective service area
  C. To prevent 802.11b devices from associating
  D. To maximize the range of the highest data rates
  E. To prevent VoWiFi multicast frames
  F. To enable support for long preambles
  B. To reduce the size of the AP's effective service area

• Question 15:

  In WLAN security, which authentication methods always create Layer 2 dynamic encryption keys? (Choose two)

  A. HTTPS Captive Portal
  B. WEP
  C. WPA2-PSK
  D. EAP-TLS
  E. Shared Key
  F. TKIP
  C. WPA2-PSK
  D. EAP-TLS

• Question 16:

  What problems may occur when there are hidden nodes in the BSS?

  A. Increase in downlink (transmitted by AP) frame retries
  B. High retransmission count for a subset of client stations
  C. Use of frame fragmentation with fragment bursts
  D. Excessive use of null data frames
  E. Duration values vary widely in each data frame
  B. High retransmission count for a subset of client stations

• Question 17:

  Given: Return Loss is the decrease of forward energy in a system when some of the power is being reflected back toward the transmitter.

  What causes high return loss in an RF transmission system?

  A. A Voltage Standing Wave Ratio (VSWR) of 1:1
  B. An impedance mismatch between devices in the RF system
  C. Cross-polarization of the RF signal as it passes through the RF system
  D. The use of different connector types in the RF system (e.g. N-type and SMA-type)
  E. Low output power at the transmitter and use of a high-gain antenna
  B. An impedance mismatch between devices in the RF system

• Question 18:

  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 19:

  What term describes the effect of increasing the intensity of an RF wave with an antenna by focusing the energy in a specific direction?
