5.1 - How to Troubleshoot Flashcards
What is change control in a large computing environment?
A formal process for making changes to applications or operating systems, involving guidelines for planning, risk assessment, testing, and rollback procedures.
Why is change control important?
It ensures changes are communicated, made in a controlled environment, and allows rollback options if problems arise.
What is a common process in a change control environment?
Planning the change, estimating risks, creating a recovery plan, testing in a lab, documenting the process, and presenting to the change control board.
What is the first step in the troubleshooting process?
Collect as much information as possible about the problem.
Why is it useful to talk directly to the user during troubleshooting?
Users can provide more detailed information about the issue than what might be captured in an email.
What should you check for when an issue arises?
Changes in the environment, patches, or modifications that might have caused the problem.
Why should you break down the information gathering process into smaller pieces?
It makes it easier to approach each symptom individually and resolve the overall problem.
What is a good practice before making changes during troubleshooting?
Take backups of the current system or application configuration.
Where can you find additional clues about changes that might have affected the environment?
Documentation from the change control board and log files of the application or operating system.
What is Occam’s Razor?
The principle that the simplest explanation is often the most likely.
What should you do if the problem is not common or usual?
Think outside the box and make a list of possible causes, testing the most obvious ones first.
What resources can help identify the root cause of a problem?
Online documentation, internal knowledge bases, and previous case documentation.
What should you do if none of your theories solve the problem?
Consider bringing in a third party or an expert who has experience with similar issues.
What is the next step after identifying a theory that resolves the issue?
Create a plan of action to implement the solution in the production environment.
Why is a rollback plan important?
It allows you to revert to the original configuration if problems occur during implementation.
