Which two statements are true about RSVP and the InServ QoS model？（）A、a drawback of implementing RSVP is the requirement to migrate to a supporting routing protocolB、RSVP uses DSCP to signal QoS requirements to routers C、RSVP is a routing protocolD、RSVP is an IP protocol that uses IP protocol ID 46， and TCP/UDP ports 3455E、RSVP specifically provides a level of service for rate-sensitive and delay-sensitive trafficF、the flow-based approach of RSVP is ideal for large， scalable implementations such as the public internet
Which two statements about the DiffServ QoS model are true？（）A、DiffServ requires RSVP to set up a path through the network to accommodate the requested QoS.B、Network traffic is identified by class， and the level of service is chosen for each class.C、The DiffServ model relies on a fairly simple mechanism to provide QoS over a wide range of equipment.D、RSVP enables the DiffServ model to provide end-to-end QoS.E、The DiffServ model is more scalable than the IntServ model.F、The flow-based approach of the DiffServ model is ideal for large scalable implementations such as the public Internet.
Which two are characteristics of RSVP？ （）A、 RSVP itself provides bandwidth and delay guarantees.B、 For RSVP to be end-to-end， all devices must support RSVP.C、 RSVP reservations are maintained by a centralized reservations server.D、 An RSVP compatible QoS mechanism must be used to implement guarantees according to RSVP reservations.
What is an advantage of the IntServ QoS model？（）A、 It supports admission control that allows a network to reject or downgrade new RSVP sessions if one of the interfaces in the path has reached the limit （that is， all reservable bandwidth is booked）.B、 RSVP signals QoS requests per individual flow. In the request the authorized user （authorization object） and needed traffic policy （policy object） are sent. The network can then provide best-effort delivery to these individual flows.C、 RSVP streamlines communication by making it unnecessary to inform network devices of flow parameters （IP addresses and port numbers）.D、 Because of the stateful RSVP architecture， continuous signaling does not have to occur.E、 The flow-based approach is scalable to large implementations， such as the public Internet， because RSVP tracks each individual flow.
Which two statements are true about the implementation of QoS？ （）A、 Implementing DiffServ involves the configuration of RSVP.B、 Implementing IntServ allows QoS to be performed by configuring only the ingress and egress devices.C、 Implementing IntServ involves the utilization of RSVP.D、 Traffic should be classified and marked by the core network devices.E、 Traffic should be classified and marked as close to the edge of the network as possible.
