Single Answer, Multiple Choice

You are the desktop engineer for your company. A user named John reports he cannot connect his computer to the office Ethernet local area network (LAN). To troubleshoot the problem, you check that the network cable is attached properly from both ends, port and computer's end. The network cable is found to be connected properly

What should you do next?

1. Check whether the link light on the network adapter card (NIC) is on.
2. Check whether the NIC is seated properly.
3. Check whether the installed NIC is compatible with the computer.
4. Check whether the correct driver for the NIC is installed on the computer.

Answer:
A. Check whether the link light on the network adapter card (NIC) is on.

Tutorial:
You should check whether the link light on the NIC is on. Before performing any major troubleshooting steps, you must check whether the link light on the NIC is on. If the link light is on, it indicates that the connection between the NIC and the network exists. If the link light is off, it indicates that there is either a problem with the cable or with the NIC.

After checking the link light status, you can perform other troubleshooting steps, such as check whether the NIC is seated on the motherboard slot properly or whether the NIC is compatible with the computer. You also can check for whether the correct driver for the NIC is installed.
