Summary
This section examines procedures for troubleshooting systems. Concepts covered include:
-
A systematic approach to problem solving.
-
Tips for troubleshooting systems.
A Essentials Objectives: -
2.1 Given a scenario, explain the troubleshooting theory
-
Identify the problem
-
Question the user and identify user changes to computer and perform backups before making changes
-
Establish a theory of probable cause (question the obvious)
-
Test the theory to determine cause
-
Once theory is confirmed determine next steps to resolve problem
-
If theory is not confirmed re-establish new theory or escalate
-
Establish a plan of action to resolve the problem and implement the solution
-
Verify full system functionality and if applicable implement preventative measures
-
Document findings, actions and outcomes
-
2.2 Given a scenario, explain and interpret common hardware and operating system symptoms and their causes
Lecture Focus Questions:
-
Why is checking the obvious first so important?
-
What place does intuition have in the troubleshooting process?
-
What is escalation and when should you do it?
-
You have identified the most likely cause of a problem and a course of action to correct the problem. When should you not immediately fix the problem?
-
How could user education be a beneficial step in the troubleshooting process?
-
How does good documentation help in the troubleshooting process?
