Nick bought a new Ethernet NIC and installed it on his new PC. He observes that the link lights on the NIC are flashing Orange. Which of the following could most likely cause this?
  1. Collisions on the network
  2. Data is being transmitted to the computer
  3. The network cable is faulty
  4. The network is down
Explanation
Answer- A - Orange blinking lights on an NIC indicates collisions on the network. Successful data transfer will display a solid green light. If the network is down or the cable is faulty, the light will not glow at all.

Key Takeaway: Whenever an NIC LED shows an orange light, it is time to consider segmenting the network.
