Your question is OSI Model and Layer Functions. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain the OSI model and the function of each layer. Relate each layer to representative protocols, devices, encapsulation, and common security controls. Briefly explain how you would use the model to troubleshoot a connectivity or security incident.
