考题 阅读下面的短文,回答问题 [When an IP packet arrives at a router, generally the router looks at the destination address of the packet, and forwards the packet to one of its network interfaces. The forwarding decision is usually done by looking up the destination address from another data structure called a forwarding table. The forwarding table is created by the router using the routing table and possible routing policies existing in the router. The router then creates a table where it lists which networks are accessible through which of the routers network interfaces. An IP router looks at every IP packet individually and does the forwarding decision on a packet-by-packet basis. If something changes in the routers routing table, a packet can take a different route from a preceding packet even if it has the same destination.] From the paragraph above,we can see that the router ( ) a forwarding table according to the routing table and possible routing policies existing in the router. When an IP packet arrives at a router, the ( ) part of packet is normally checked by the router. An IP router checks every IP Packet individually and makes the forwarding decision based on ( ).A.is generating B.generate C.is generated D.generates A.forwarding table B.network interfaces C.routing policies D.destination address A.the destination address and network interfaces B.forwarding table and network interfaces C.the destination address and forward table D.routing policies and routing table

考题 ●Border Gateway Protocol(BGP) is inter-autonomous system (71) protocol. BGP is based on a routing method called path vector routing. Distance vector routing is not a good candidate for inter-autonomous system routing because there are occasions on which the route with the smallest (72) count is not the preferred route. For example, we may not want a packet through an not secure even though it is the shortest route. Also, distance vector routing is unstable due to the fact that the routers announce only the number of hop counts to the destination without actually defining the path that leads to that (73) .A router that recevives a distance vector advertisement packet may be fooled if the shortest path is actually calculated through the receiving router itself. Link (74) routing is also not a good candidate for inter-autonomous system routing because an Internet is usually too big for this routing method. To use link state routing for the whole internet would require each routex to have a huge link state database. It would also take a long time for each router to calculate its rousting (75) using the Dijkstra algorism.(71)A. routingB. switchingC. transmittingD. receiving(72)A. pathB. hop `C. routeD. packet(73)A. connectionB. windowC. sourceD. destination(74)A. statusB. searchC. stateD. research(75)A. tableB. stateC. metricD. cost
