CWNP CWNA-106 Online Questions & Answers

• Question 11:

  When performing a site survey for a Multiple Channel Architecture (MCA) system in a multi- tenant building with five floors, what aspect should you, as the site surveyor, keep in mind?

  A. The RF interference caused by passing airplanes supporting on-board Wi-Fi should be a prime consideration.
  B. The omni-directional antennas of the access points should beoriented parallel to the floor to maximize the coverage pattern across as many floors as possible.
  C. The channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to other floors.
  D. The Fresnel Zone is completely blocked between floors so each floor is considered a separate site survey.
  C. The channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to other floors.

• Question 12:

  Return Loss is the decrease of forward energy in a system when some of thepower is being reflected back toward the transmitter. What will cause high return loss in an RF transmission system, including the radio, cables, connectors and antenna?

  A. A Voltage Standing Wave Ratio (VSWR) of 1:1
  B. An impedance mismatch between components in the RF system
  C. The use of cables longer than onemeter in the RF system
  D. High output power at the transmitter and use of a low-gain antenna
  B. An impedance mismatch between components in the RF system

• Question 17:

  In an enterprise WLAN, what condition will prevent a dual-band VHT/HT client device from performing a fast and seamless transition (i.e. latency-sensitive applications are notdisrupted) between two access points that are managed by the same WLAN controller?

  A. The current AP is using channel 1 and the new AP is using channel 40.
  B. The SSID of the current AP does not match the SSID of the new AP.

• Question 20:

  What statements describe industry practices for communication protocols between WLANcontrollers and controller-based APs? (Choose 2)

  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 vendorsuse 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 broadcastprotocol for controller discovery by controller-based APs.
