The CompTIA 7-Step Troubleshooting Methodology Explained - Network+ N10-009
Watch on YouTube The CompTIA 7-step troubleshooting methodology is the backbone of Domain 5 on the Network+ N10-009 exam, which carries 24% of the exam weight. This video breaks down every step in order: identify the problem, establish a theory of probable cause, test the theory, establish a plan of action, implement the solution or escalate, verify full system functionality and implement preventative measures, and document findings and outcomes. We also cover the three OSI troubleshooting approaches (top down, bottom up, and divide and conquer), when to escalate, and a mental shortcut for matching symptom keywords to the right OSI layer on exam day. Watch the next video in the playlist for cable testing tools, wire maps, TDR, OTDR, and loopback diagnostics.
