Question

1) Chapter 13 A: Discuss what methods you have used for troubleshooting and how these techniques compare to the methods of others. There are a great variety of tools available for troubleshooting, discuss what tools you have used to fix network problems. If you have not used any, research several and in either case determine the advantages and disadvantages of each.

Answer 1

A have not used any troubleshooting.

The research of all troubleshooting

1)Top down approach :-you work from the open system interconnection models application layer down to the physical layer.The OSI seven layer networking model and TCP/IP four layer this method is u need to have access to the clients application layer software to initiate the troubleshooting process and if the software is only installed on small number of machine.

2)bottom up approach:-this approach starts from osi model physical layer and moves up towards the application layer.the disadvantage of this approach is for large network it is time consuming process .

3)divide and conquer approach using this approach u start at the middle of the OSI model stack and then based on your findings u move up or down on OSI stack.the disadvantage with this is it is not sure of using weather top down or bottom up.

4)swap components approach is the strategy of this approach is to physically move components and observe weather the problem move with the componenet or not .the disadvantage of this approach is u r isolating the problem to only a limited set of physical elements and not gaining any insight into what is happening.

5) follow the path approach is based on the path that packets take through the network from Source to the destination.

6)spot the difference approach is this approach compares network devices that are operating correctly to the devices that are not operating as expected and gather clues by spotting significant difference.
