1.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 router’s 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 router’s 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

2.A route－based VPN is required for which scenario? ()A. when the remote VPN peer is behind a NAT deviceB. when multiple networks need to be reached across the tunnelC. when the remote VPN peer is a dialup or remote access clientD. when a dynamic routing protocol such as OSPF is required across the VPN

3.Which one of the following statements best explains the split horizon rule used in distance vector routing protocols?()A. Only routers can split boundaries (horizons) between concentric networks.B. Each AS must keep routing tables converged to prevent dead routes from being advertised across boundaries.C. Networks can only remain fully converged if all information is sent out all active interfaces.D. Information about a route should not be sent back in the direction from which the original update came.E. Distance vector protocols need fall back routers that are responsible for momentary loops.

4.An internet is a combination of networks connected by (71) .When a datagram goes from a source to a (72) ，it will probably pass many (73) until it reaches the router attached to the destination network．A router receives a (74) from a network and passes it to another network．A router is usually attached to several networks．When it receives a packet，to which network should it pass the packet?

    正确答案： D
    解析： 互联网是由不同的网络通过路由器互联起来的。当数据包从源地发往目的地时，在到达目的地网络之前它可能经过多个路由器。路由器从一个网络接收到数据包之后就转发到另外一个网络。然而，一个路由器往往与几个网络连接，当路由器接收到一个数据时，它应该将数据包传向哪个网络呢？这将基于路径最优化决策。
