Which model is the only QoS model with no mechanism to classify packets?

  • hard QoS
  • DiffServ
  • best-effort
  • IntServ

Explanation: The best-effort model has no way to classify packets; therefore, all network packets are treated the same way. Without QoS, the network cannot tell the difference between packets and, as a result, cannot treat packets preferentially.
