Your question is Deep OSI Layer Discussion with Packet-level Detail. 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 OSI layers in depth with packet-level detail on how traffic initiates and traverses.
Cover the role and protocol data unit of each layer, then trace an HTTPS request from a client application to a remote server. Explain DNS resolution, ARP or Neighbor Discovery, TCP connection establishment, TLS, encapsulation, switching, routing, NAT, and decapsulation. Distinguish the conceptual OSI model from the practical TCP/IP stack, and identify what changes at each hop.
Scope: Focus on IPv4 and Ethernet, with brief IPv6 comparison where relevant.
