The structured network troubleshooting process is triggered by a fault report. The basic principle is to simplify troubleshooting by narrowing down or isolating all possible causes of a fault into several small subsets. In what sequence are structured network troubleshooting steps carried out? 1. Information collection 2. Fault identification 3. Cause list 4. Troubleshooting assessment 5. Fault analysis 6. One-by-one check 7. Fault rectification
