Sample cards
What is the first step of the CompTIA troubleshooting methodology?
Identify the problem — gather information, question users, identify symptoms, determine if anything has changed, and duplicate the problem if possible.
What are the seven steps of the CompTIA troubleshooting methodology, in order?
1) Identify the problem, 2) Establish a theory of probable cause, 3) Test the theory, 4) Establish a plan of action, 5) Implement the solution or escalate, 6) Verify full functionality and implement preventive measures, 7) Document findings, actions, outcomes, and lessons learned.
After identifying the problem, what is the next troubleshooting step?
Establish a theory of probable cause — including questioning the obvious (e.g., is the cable plugged in?).
What does "question the obvious" mean when establishing a theory of probable cause?
Check simple, common causes first — power, cables seated, correct port, link lights — before assuming a complex failure.
What do you do after establishing a theory of probable cause?
Test the theory to determine the cause — confirm it before acting on it.
