When a station drops its speed due to Automatic Rate Selection it:

  1. Decreases its power output level to transmit at a slower speed.
  2. Changes the data modulation type or the code keying sequence.
  3. Increases its power output level to attempts to maintain connection speed.
  4. Increases the fragmentation threshold to maintain greater throughput.

Answer(s): B

Explanation:

Since each link speed has a different modulation technique associated with it, the modulation type and the code spreading technique is changed when the speed drops. However, there is no change in power output level and power output does not affect throughput/speed. Thus the answer should be B.



Which of these spread spectrum technologies requires Line of Sight to operate properly? (Select all that apply.)

  1. Frequency Hopping
  2. Infrared
  3. Direct Sequencing
  4. Laser

Answer(s): A,C

Explanation:

According to the study guide, all spread spectrum technologies require line-of-sight (RF LOS) to operate properly. Therefore, the answer should be A, C.



Which of these is NOT part of the RF coverage map that will be included with the RF Site Survey Report?

  1. Maximum number of users for each cell.
  2. Coverage area of each cell.
  3. Channel of each cell.
  4. Power settings of each access point.
  5. Antenna type used with each access point.

Answer(s): A



In terms of RF power, 1 Watt (1000 mW) = dBm.

  1. 3
  2. 10
  3. 20
  4. 30
  5. None of the above.

Answer(s): D



Where is the SSID stored in a client computer?

  1. PC Card firmware
  2. Windows registry
  3. On the Master Boot Record of the hard drive.
  4. On the hard drive as an encrypted file.
  5. SSIDs are not stored on client computers.

Answer(s): E
