试题1
TheAddress Resolution Protocol(ARP)wasDeveloped to enableCommunication onAn InternetworkAnd performA required function in IP routing.ARP liesBetween layers（ ）of the OSI model,andAllowsComputers to introduce each otherAcrossA network prior toCommunication.APR finds the（ ）address ofA host from its known（ ）address.BeforeADevice sendsADatagram toAnotherDevice,it looks in itsARPCache to see if there isA MACAddressAndCorresponding IPAddress for theDestinationDevice.If there is no entry,the soureeDevice sendsA（ ）message to everyDevice on the network.EachDeviceCompares the IPAddress to its own.Only theDevice with the matching IPAddress replies withA packetContaining the MACAddress for theDevice（except in theCase of “proxyARP”）.The sourceDeviceAdds the（ ）device MACAddress to itsARP table for future reference.查看答案

试题10
Traditional IP packet forwarding analyzes the （ 1）IP address contained in then network layee header of each packet as the packet rravels from its sourse to its final destination. A router analyzes the destination IP address independently at each hop in the network. Dynamic （ 2） protocols or staitic 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 （ 3）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 its （ 4）.New techniques are therefore required to address and expand the functionality of an IP-based network infrastructure. This first chapter concertrates on idenfifying these restrictions.and presents a new architecture,known as multiprotocol（ 5）switching,that provides solutions to some of this restrictions.
