• Question 53:

  If an 802.11 RF transmission reaches a receiving antenna simultaneously by direct and indirect (reflected) paths, what effect will the reflected signal have on the signal that took the direct line-of- sight path?

  A. The direct signal will only be received if the reflected signal is more than 180 degrees out of phase.
  B. The direct signal cannot be received if the indirect signal is less than 90 degrees out-of-phase.
  C. The signals will be distorted if the indirect signal arrives simultaneously at the receiver, but 90 degrees out-of-phase.
  D. If the signals are in-phase, they will combine together, cancel one another out, and create a null.
  C. The signals will be distorted if the indirect signal arrives simultaneously at the receiver, but 90 degrees out-of-phase.

• Question 54:

  What phrase defines Equivalent Isotropically Radiated Power (EIRP)?

  A. Radio transmitter output power minus attached cable and connector loss
  B. Radio transmitter output power only

  D. Reflected power due to an impedance mismatch in the signal path
  E. Power supplied from the transmission line to the antenna's input
  C. Power supplied to the transmit antenna input plus antenna gain

  A. Signal strength of access point beacons
  B. Proximity to potential access points
  C. Retry rate of probe request and response frames
  D. Average round trip time to reach the IP gateway
  E. Number of nearby RF interference sources

• Question 57:

  In a long-distance RF link, what statement about Fade Margin is true?

  A. Fade Margin is an additional pad of signal strength designed into the RF system to compensate for unpredictable signal fading.
  B. The Fade Margin of a long-distance radio link should be equivalent to the receiver's antenna gain.
  C. A Fade Margin is unnecessary on a long-distance RF link if more than 80% of the first Fresnel zone is clear of obstructions.
  D. The Fade Margin is a measurement of signal loss through free space, and is a function of frequency and distance.
  A. Fade Margin is an additional pad of signal strength designed into the RF system to compensate for unpredictable signal fading.

• Question 58:

  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
  B. Business justification
  C. User productivity impact

• Question 59:

  Given: In a single channel architecture (SCA) WLAN system, 802.11n (HT) APs should not share an SSID with 802.11g (ERP) APs.

  What is the reason for this recommendation?

  A. Client stations would see two different sets of AP capabilities as they roam between APs with the same BSSID.
  B. The added range of 802.11n APs would cause additional co-channel interference.
  C. The additional beacon material in 802.11n beacons would confuse 802.11b/g client stations.
  D. Beacons from 802.11n APs use 40 MHz channels, while beacons from 802.11g APs use 20 MHz channels.
  A. Client stations would see two different sets of AP capabilities as they roam between APs with the same BSSID.

• Question 60:

  What statements describe industry practices for communication protocols between WLAN controllers and controller-based APs? (Choose two)

  A. All vendors use the same protocol so that APs will interoperate with WLAN controllers from other vendors.
  B. Some vendors use proprietary protocols, and some vendors use protocols based on public standards like RFCs.
  C. For most vendors, the controller-based APs maintain data and control tunnels with at least two controllers for immediate failover and redundancy.
  D. All vendors support at least one L2 or L3 broadcast protocol for controller discovery by controller- based APs.
  E. All vendors recommend using L2 (instead of L3) controller discovery and tunneling protocols in large enterprises.
  B. Some vendors use proprietary protocols, and some vendors use protocols based on public standards like RFCs.
