You discover that a device on your network is creating a broadcast storm. You have switches that do not use VLANs or Spanning Tree Protocol. What is the most likely cause of the storm?
  1. A routing loop
  2. A switching loop
  3. A faulty switch
  4. A misconfigured router
Explanation
Answer: B - A switching loop is the most common cause of a broadcast storm.

Key Takeaway: A switching loop occurs when there are two or more different pathways between any two devices. This is the most common cause of broadcast storms. Ways to fight these storms include segmenting your network with routers or VLANs, implementing the spanning tree protocol, and filtering broadcasts with layer 3 equipment such as routers or multilayer switches.
