You are a technician and a network user calls up complaining that he is not able to access the network resources. What is the first thing that you should do?
  1. Check for a link light on the network adapter.
  2. Check the TCP/IP settings on the computer.
  3. Check the network cable.
  4. Check the switch.
Explanation
Answer: A - If a user is not able to access network resources, the first thing that you should do is to check to be sure the link lights on the NIC are working. The link lights should show a solid or blinking green.

Key Takeaway: If the link LEDs are working, then you can assume that physical connectivity is intact and proceed further with the troubleshooting. If the link lights do not work, then troubleshoot for no physical connectivity.
