The technician checking for a link light when assisting a user who cannot connect to a network resource is an example of using a bottom-to-top approach in troubleshooting methodology.
The bottom-to-top approach involves starting at the physical layer of the network and working upwards towards the application layer. This approach helps to systematically identify and resolve network issues.
In this scenario, checking for a link light at the physical layer is the first step in identifying potential network connectivity issues. If the link light is not present, it could indicate a problem with the physical cable, connector, or network port.
Establishing a plan of action would come after the initial assessment, where the technician would decide on the appropriate next steps to resolve the issue. Documenting a finding would occur after the issue has been identified and resolved. Questioning the obvious is not applicable in this scenario as the technician is performing a necessary step in the troubleshooting process.
Overall, the technician is using a structured and logical approach to troubleshoot the issue by starting at the bottom layer of the OSI model and working upwards, ensuring that each layer is functioning properly before moving on to the next.
