Your question is Network Reliability to Prevent Loss. 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).
Design a reliable network paradigm to avoid packet loss.
Clarify the target environment, traffic patterns, failure assumptions, and what “avoid” means in practice, for example best-effort reduction versus strict loss bounds. Then propose the end-to-end design, including congestion control, buffering, retransmission or redundancy strategy, observability, and how you would validate it under scale and failure.
