You notice a workstation on your network is continuously trying to broadcast packets over and over. What is the most likely cause?
  1. Routing loop
  2. Switching loop
  3. Short in the Ethernet cable
  4. Faulty NIC or NIC driver
Explanation
Answer: D - A faulty NIC or NIC driver is the most likely cause of a network continuously trying to broadcast packets over and over.

Key Takeaway: A failing NIC will often send out a lot of packets that are just erroneous artifact. In modern networks, this will not affect the network much as the switch will probably prevent a broadcast storm, but a NIC wildly sending out a lot of erroneous packets is a hallmark of a failing NIC or corrupt driver.
