Osi Model — Cisco CCNA (200-301) Practice Questions
The OSI model is a seven-layer conceptual framework that standardizes how different network functions are organized and how devices from different vendors interoperate. Each layer, from Physical at layer 1 through Application at layer 7, defines specific responsibilities such as framing, addressing, routing, and session management. The CCNA exam uses the OSI model as a foundational reference throughout every topic, including troubleshooting, because identifying which layer a problem occurs at guides the correct diagnostic and resolution approach. Candidates must be able to map protocols, devices, and data units to the correct OSI layer.
