When troubleshooting a network issue, a technician decides to employ a bottom-to-top approach using the OSI model. From which OSI layer would they begin their troubleshooting process?
Physical layer
Network layer
Application layer
Transport layer
When applying the bottom-to-top (bottom-up) approach in the OSI model, the technician starts at the Physical layer. This layer encompasses the network's tangible components-cables, connectors, and hardware interfaces-making it the first place to check for link lights, proper terminations, or damaged media before examining higher-layer configurations and protocols.
