What is the principle that is applied when a network technician is troubleshooting a network fault by using the divide-and-conquer method?

  • Testing is performed at all layers of the OSI model until a non-functioning component is found.
  • Once it is verified that a component in a particular layer is functioning properly, testing can then be performed on any other layer.
  • Testing is performed at Layer 7 and at Layer 1, then at Layers 6 and 2, and so on, working towards the middle of the stack until all layers are verified as operational.
  • Once it is verified that components in a particular layer are functioning properly, it can then be assumed that components in the layers below it are also functional.
    Answers Explanation & Hints:

    The nature of the OSI and TCP/IP layered models is that upper layers are dependent on lower layers. So when troubleshooting, if a particular layer is found to be working correctly then it can be assumed that all layers below it are also functioning correctly.
