Questions and Answers

What is the purpose of a formal change control process in a large computing environment?

To make it easier for everyone to implement changes without restrictions

To increase the complexity of making changes to applications and operating systems

To limit the number of changes that can be made to the network

To ensure changes are made in a controlled environment and can be rolled back if needed (correct)

What is the purpose of having alternate plans during implementation?

To delay the resolution process

To complicate the troubleshooting process

To confuse the change control board

To ensure a backup in case the primary fix fails (correct)

What is the role of rollback in the troubleshooting process?

To implement additional resources to speed up the process

To create preventative measures for future problems

To revert to the original configuration if something unexpected happens (correct)

Study Notes

Troubleshooting process for resolving issues with broken systems or applications
First step: collect as much information as possible about the problem
- Get details from users, such as screenshots and error messages
- Multiple symptoms may indicate one or more underlying problems
- Reach out to users for additional information
- Check system records for changes or patches that could impact performance
- Back up systems before making changes
- Review change control board documentation for environmental changes
- Check application or operating system log files for insights
Second step: theorize on possible root causes
- Simplest explanation is often the most likely (Occam's razor)
- Make a list of possible causes, prioritize common ones
- Clues from documentation or knowledge bases may help identify root cause
Third step: test theories and identify root cause
- Start with common causes, move on to less likely ones
- Bring in third party or expert if no progress is made
Fourth step: implement a plan of action
- After identifying the root cause, create a plan for addressing it
- Incorporate a method for reverting changes if necessary
- Consult vendor documentation for recommended implementation steps.
