Chapter 4: Domain 4 Troubleshooting
✓ 4.1 Given a scenario, implement the following network troubleshooting methodology:
■ Identify the problem
■ Gather information
■ Duplicate the problem
■ Question Users
■ Identify symptoms
■ Determine if anything has changed
■ Approach multiple problems individually
■ Establish theory of probable cause
■ Question the obvious
■ Consider multiple approaches
■ Top-to-bottom/bottom to top of OSI Model
■ Divide and conquer
■ Test the theory to determine cause
■ Once theory is confirmed, determine the next steps to resolve the problem
■ If theory is not confirmed, re-establish new theory or escalate
■ Establish a plan of action to resolve the problem and identify potential effects
■ Implement the solution or escalate as necessary
■ Verify full system functionality and if applicable implement preventative measures
■ Document findings, actions, and outcomes
