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
A router receives a packet on interface 172.16.45.66／26. The source IP of the packet is 172.16.45.127／26 and the destination is 172.16.46.191／26.How will the router handle the packet?()
A. The destination is a host on another subnet, so the router will not forward the packet.B. The destination is a host on the same subnet, so the router will forward the packet.C. The destination is a broadcast address, so the router will not forward the packet.D. The destination is a network address, so the router will forward the packet.

考题
We have already covered the topic of network addresses. The first（71） in a block (in classes A,B,and C) defines the network address. In classes A,B,and C,if the hostid is all ls, the address is called a direct broadcast address. It is used by a.（） to send a packet to all hosts in a specific network. All hosts will accept a packet having this type of destination address. Note that this address can be used only as a （73）address in an lP packet. Note also that this special address also reduces the number of available hostid for each netid in classes A,B,and C.
In classes A,B,and C,an address with all Is for the netid and hostid (32 bits) defines a（74） address in the current network.A host that wants to send a message to every other host can use this address as a destination address in an IP packet. However,a router will block a packet having this type ofaddress to confine the broadcasting to the （75） network. Note that this address belongs to class E.A.router
B.switch
C.huB.
D.firewall

Traditional IP packet forwarding analyzes the（ ）IP address contained in the network layer header of each packet as the packet travels from its source to its final destination.A router analyzes the destination IP address independently at each hop in the network.Dynamic（ ）protocols or static configuration builds the database needed to analyze the destination IP address（the routing table）.The process of implementing traditional IP routing also is called hop-by-hop destination-based（ ）routing.Although successful，and obviously widely deployed，certain restrictions，which have been realized for some time，exist for this method of packet forwarding that diminish is（请作答此空）.New techniques are therefore required to address and expand the functionality of an IP-based network infrastructure.This first chapter concentrates on identifying these restrictions and presents a new archiecture，known as multiprotocol（ ）switching，that provides solutions some of these restrictions.
A.reliability
