Network Proposal Paper
Below are diagrams of a network topology diagram.
In this network, 12 trouble tickets are issued to fix the connectivity problem. Select any three tickets and use the troubleshooting approach to diagnosis the problems and implement solution to the problem.
Your paper should address the following.
- What was your troubleshooting plan?
- What methods did you use to diagnose the problem? You should address here why the device in the ticket has problem.
- How did you arrive at identifying the problem? Here you should address other protocols or technologies that are ruled out by using verifying commands
- Implementation solution to the problem with verification

Network Troubleshooting Methodology
The process of troubleshooting of a network holds great significance to ensure the smooth functioning of all the processes. It makes sure that all the problems are eliminated from the system and there are no further issues that may cause a hindrance. However, the troubleshooting methodology involves many of steps which should be carried out in a professional manner. Steps to troubleshoot a network
1. Identify the Problem
- Identify Symptoms
- Question Users
- Determine if anything is changed
2. Establish a theory of Probable Cause
3. Question the obvious:
So, this is the step where you will devote your energies to confirm you narrowed-down problem. For example, in the case of loss of a DHCP address, you can type ipconfig/renew on the computer to check if the DHCP address is restored. If it is not restored, then it means that the DHCP server for that computer has not been put online yet. This will let you relate all your previous findings in order to think about a common problem which could have caused it.
4. Test the theory to determine the cause
5. Establish a plan of action to resolve the problem and identify potential effects
6. Implement the solution or escalate as necessary
7. Verify full system functionality and if applicable implement preventative measures
8. Document findings, actions and outcomes
