Troubleshooting Methodology Flashcards
What is the key action in identifying the problem during troubleshooting?
Gather information to understand the problem fully by asking clear questions, looking for error messages, and reviewing recent changes.
What are the steps to identify a problem during troubleshooting?
- Ask open-ended questions to the user.
- Look for error messages or warning signs.
- Review recent changes or events related to the issue.
What are some changes to ask the user about when identifying the problem?
- Hardware changes.
- Software updates or installations.
- Configuration changes.
- Security patches or updates.
What techniques help gather information when identifying a problem?
- Ask for specific details like error codes.
- Check for common symptoms (e.g., noise, slow performance).
- Assess the scope (localized or widespread issue).
- Determine what has already been tried.
What is the key action in establishing a theory of probable cause during troubleshooting?
Based on gathered information, propose the most likely cause of the problem, considering common causes and possible theories.
What are the steps for establishing a theory of probable cause?
- Consider common causes (hardware, software, network).
- Look for simple issues first.
- Conduct research using external and internal resources.
- Reproduce the problem for confirmation.
What is the key action in testing a theory to determine the cause?
Test the theory by performing diagnostics or changes to confirm or rule out the suspected cause.
What are the steps in testing the theory?
- Perform small, non-invasive tests to verify the theory.
- If incorrect, formulate a new theory and test again.
- Escalate if necessary or when no progress is made.
What is the key action in establishing a plan of action to resolve the problem?
Develop a clear plan based on the tested theory to fix the problem, considering resources, time, and impact.
What should be considered when establishing a plan of action?
- Choose between repair, replace, or workaround.
- Assess costs, time, and resources.
- Obtain necessary authorization and minimize disruption.
What is the key action in verifying system functionality?
Test the system to confirm that the issue has been resolved and ensure all components function as expected.
What are the steps to verify system functionality after implementing a solution?
- Confirm the specific issue is resolved.
- Test for full system functionality, checking hardware and software.
- Perform updates and implement preventative measures to avoid recurrence.
What is the key action in documenting the troubleshooting process?
Record the issue, resolution steps, and preventive measures for future reference and learning.
Why is documentation important in troubleshooting?
It helps track findings, ensures steps are not repeated, and improves future troubleshooting efficiency.
