考题 The Internet is based on a connectionless end-to-end packet service, which traditionally provided best-effort means of data ( )using the Transmission Control Protocol/Internet Protocol Suite. Although the ( )design gives the Internet its flexibility and robustness, its packet dynamics also make it prone to congestion problems,especially at ( )that connect networks of widely different bandwidths.The initial QoS function set was for internet hosts.One major problem with expensive wide-area( )links is the excessive overhead due to small Transmission Control Protocol packets created by applications such as telnet and rlogin. The Nagle ( ),which solves this issue,is now supported by all IP host implementations.A.transformationB.transportationC.processingD.progressingA.connectionlessB.connectionC.connection-orientedD.connotationA.hostsB.switchesC.routersD.computersA.interconnectionB.networkC.internetD.webA.technologyB.problemC.structureD.algorithm

考题 Which two routing interface parameters are supported in OSPF implementations?() A. retransmit - intervalB. de ad - intervalC. stub areaD. virtual linkE. NSSA area

考题 Refer to the exhibit. You have completed an OSPF implementation, and you are verifying OSPF operation. You notice that router A and router B are stuck in the two - way state. From the show ip ospf interface command output, what is the cause of this issue?()A. All OSPF implementations must have at le ast one interface in area 0.B. You are attempting to run in the broadcast mode over an NBMA interface.C. Both routers are configured to function as a BDR; therefore, there is no DR router.D. Someone has changed the OSPF router ID; therefore you must clear the OSPF process.E. The OSPF priority is set to 0 on both routers; therefore neither can become the DR.

考题 The Schuyler and Livingston Iron Works has been working on getting its network security under control. It has set up VPN with IPSec links to its suppliers.

考题 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.
