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. What do flashing orange link lights usually indicate?
  1. There are 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 indicate collisions on the network. Solid green lights represent successful data transfer. 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.
