• Question 1100:

  Wireless network users recently began experiencing speed and performance issues after access point 2 (AP2) was replaced due to faulty hardware. The original network was installed according to a consultant's specifications and has always

  worked without a problem.

  You, a network technician, have been tasked with evaluating the situation and resolving the issues to improve both performance and connectivity. Refer to the following diagram and perform any NECESSARY changes to the wireless and

  wired infrastructure by adjusting devices.

  Note: Adjust the LEAST number of devices needed to fix the issue, all blue icons in the image are clickable. When you feel the simulation is complete please select the Done button.

  

  

  

  Correct Answer. Check the answer below:
  Check the answer below:

  Since we know that the network was running perfectly before replacing AP2 we should start by looking at this new device thatwas used to replace the old one. Here we see that the other AP's have hard coded the speed and duplex settings to

  100/full, while AP2 is set to auto/auto.

  Also, the other AP's have been configured to use 802.11G, while AP2 is using 802.11B.

  Finally the channel that AP2 is using overlaps with AP1 which can cause problems.

  Channels 1, 6, and 11 are spaced far enough apart that they don't overlap. On a non-MIMO setup (i.e. 802.11 a, b, or g) you should always try to use channel 1, 6, or 11. Since AP1 is using1, and AP3 is using 11, AP2 should be using 6.
