- 1Open sends at a set arrival rate; closed has fixed users waiting for replies
- 2Open uses HTTP/1.1; closed uses HTTP/2 or gRPC connections
- 3Open tests are public; closed tests run only inside the company
Show the answer
Correct answer: Open sends at a set arrival rate; closed has fixed users waiting for replies
Explanation
With a closed model, a slow server lowers the request rate and hides overload. An open model keeps sending, like real traffic, and shows queueing.
