Apply troubleshooting methodology and gather evidence in scenario-based support

By the end you’ll be able to

• Apply the CompTIA troubleshooting methodology: identify the problem, establish a theory of probable cause, test the theory, establish a plan of action, implement the solution, verify full system functionality, and document findings, actions, and outcomes.
• Gather evidence by interviewing users, identifying recent changes, backing up data when appropriate, and reproducing or isolating symptoms without causing unnecessary disruption.
