CWNA-107

Review 95 CWNA-107 practice questions with answer explanations and community insights.

Question 1

What factor does not influence the distance at which an RF signal can be effectively received?

  1. Free Space Path Loss
  2. Receiving station’s radio sensitivity
  3. Transmitting station’s output power
  4. Receiving station’s output power

Question 2

A WLAN transmitter that emits a 50 mW signal is connected to a cable with 3 dB loss. If the cable is connected to an antenna with 9dBi gain, what is the EIRP at the antenna element?

  1. 23 dBm
  2. 26 dBm
  3. 13 dBm
  4. 10 dBm

Question 3

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

  1. The Fade Margin is a measurement of signal loss through free space and is a function of frequency and distance.
  2. The Fade Margin of a long-distance radio link should be equivalent to the receiver’s low noise filter gain.
  3. A Fade Margin is unnecessary on a long-distance RF link if more than 80% of
  4. Fade Margin is an additional pad of signal strength designed into the RF system to compensate for unpredictable signal fading.

Question 4

What wireless networking term describes the increase of RF energy in an intentional direction with the use of an antenna?

  1. Directed Radiation
  2. Active Amplification
  3. Passive Gain
  4. Beam Digression

Question 5

Which directional antenna types are commonly used by indoor Wi-Fi devices in a MIMO multiple spatial stream implementation?

  1. Dish and grid
  2. Dipole and yagi
  3. Grid and sector
  4. Patch and panel
