Which QoS model uses the DSCP bits to mark packets and provides 64 possible classes of service?

  • best-effort
  • IntServ
  • DiffServ
  • FIFO

Explanation: The DiffServ model uses 6-bits known as the DiffServ Code Point (DSCP) bits to mark traffic and offers a maximum of 64 possible classes of service. Diffserv-aware routers can then implement per-hop behaviors (PHBs) that can control packet forwarding based on the specified class of service.
