Your question is HTTP Request Through Network Layers. 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 how an HTTP GET request between two machines on an internal network works on Layer 2, Layer 3, and Layer 4.
Assume the client already knows the server hostname and explain the packet flow from name resolution through the response. Cover both same-subnet and routed-subnet cases, including ARP, Ethernet framing, IP addressing, TCP establishment, ports, acknowledgments, and failure points. State how you would verify the explanation using packet captures and host telemetry.
