You are trying to find out why a network card will not connect to the network. Which of the following should you check first?

Driver
Link light
Processor
RJ-45 cable

Explanation

Answer: B -If the network card will not connect to the network, you should check the link light first.

Key Takeaway: When it comes to network cards, the first thing you want to check is the link light on the back of the computer to verify that there is an actual connection to the network. If the link light does not glow, run the loopback test. If the link light does glow, then you should proceed with troubleshooting the next phases of the network.
