Davis has noticed that one of the systems on his network has sporadic connection to the network. He is running a 100BaseT network, and the workstation is about 150 meters away from the switch. What is the most likely cause of the intermittent network issues?
  1. A wireless router is conflicting with the wireless adaptor on the switch
  2. The cable to the host is too long and the signal has attenuated
  3. He needs to use coaxial cable for his 100baseT network
  4. The bridge he had installed to propagate the signal has failed
Explanation
Answer: B - The cable to the host is too long and the signal has attenuated. 100BaseT networks have a maximum length of 100 meters between devices.

Key Takeaway: The longest cable run you should have in a 100BaseT network is 100 Meters. Anything beyond this can lead to signal attenuation and intermittent network problems. You can fix this by shortening the run or putting a repeater, not a bridge, in place so that the run is now less than 100 meters.
