思科CISCO笔试题目+解析和答案思科(CISCO)笔试题目+解析和答案一题:解:求至少几人及格,也就是求最多多少人不及格,情况分为:做对0个,做对1个,做对2个,做对3个,做对4个,做对5个,为了使不及格人最多,不妨对做对0个的人说,为何不把你的做错的两道给做对3个或4个的人呢,这样你还是不及格并且可以多增加人不及格,这样做对0个把自己的错误2个题给别人,他错3个,同理做对1个的把自己的.一个错误题给别人,这样保证了不及格人最多,经过以上分析,现在不及格人最多时,只有一下几种情况:做对2个,做对3个,做对4个,做对5个。
分别设人数为:X2,X3.X4.X5,则:当X2最大是,至少及格人数为:100-X2X2+X3+X4+X5=100 (1)总错误题数为:100*5-(80+72+84+88+56)=120则:3X2+2X3+X4=120 (2)(2)-(1)得:2X2+X3-X5=20 (3)可以看出要想使X2最大,则X3最小,X5最大,则:X3=0,X5=56,则X2=38,X4=6,即做对2个38,做对3个0,做对4个6,全对56。
也就是说至少有100-X2=100-38=62人及格,对结果进行分析:对于第五题只有56人做对,那么38+6=44,即做对4个和做对2个的都有第五题做错,那么做对2个的38人只能在前4道题中错2道:显然很好分配,分法之一:38-28=10,做错1和2的10人,做错1和3的20-10=10人,做错2和3的16-10=6人,做错2和4的12人。
二题:10人和一个司机时间最少,则车接第十人正好与前面9个人一起到达终点设第一个人坐车T1小时,步行T2小时,求T1+T2,则:100T1+5T2=1000 (1)假设在D点把第一人放下,在C点车回来接到第二人,则车从D-C 时间为:t=(100T1-5T1)/105,设从车载第二人开始开始到车追上第一人时,第一个走了s公里到达E点则:车在C点时,车与第一人的距离为105t=100T1-5T1=95T1,则:(95T1+s)/100=s/5 (2)即:5T1=s第一人从D-E走了:5t+s公里同理可知第三人到第10 人与第二人一样,则车一共送10人次,回头接人(空车)9次则第一人共走了9*(5t+s)=5T2即:9*[5*(100T1-5T1)/105+S]=5T2 (3)由(1),(2)(3)可得:T1=70/13,T2=1200/13,则:T1+T2=1270/13=97.69小时。
1. what could be possible causes for the "Serial0/0 is down"interface status? 这可能是为“Serial0 / 0的可能原因是向下”接口的状态?TWOA.a layer 1 problem exists.1层存在问题D.an incorrect cable is being used。
2.before installing a new,upgraded version of the ios,what should be checked on the router,and which command should be used to gather this information?在安装一个新的,升级的IOS版本,应该怎样检查路由器上,并命令应该被用来收集这些资料?B.the amount of avaiable flash and ram 缴费的闪存和RAM的数量D.show version 显示版本3.refer to the exhibit. which two statements are true about inter VLAN routing in the topology that is shown in the exhibit?(choose two)指展览。
这两个语句是对国际米兰的是在展会上展出的拓扑路由的VLAN是否属实?D. the FastEthernet 0/0 inerface on router1 must be configured with subinterfaces.关于路由器1的在FastEthernet 0/0 inerface 必须配置子接口F.the FastEthernet 0/0 interface on router1 and switch2 trunk ports must be configured using the same encapsulation type. 对在FastEthernet 0/0 接口上路由器1和交换器2中继端口必须配置使用相同的封装类型。

第一部分计划和设计Design a simple LAN using Cisco Technology使用思科技术设计一个简单的局域网1、Which of the following devices can an administrator use to segment their LAN? (Choose all that apply)下列哪个设备能使管理员分段他们的局域网?A. HubsB. RepeatersC. SwitchesD. BridgesE. RoutersF. Media ConvertersG. All of the aboveA 集线器B 中继器C 交换机D 网桥E 路由器F 媒体转换G 所有答案:CDE解析:Routers, switches, and bridges don’t transmit broadcasts. They segment a large Cumber some network, into multiple efficient networks.路由器,交换机,和网桥不能传输广播,它们分一个大的网络,到多个网络错误答案:A. Hubs is incorrect because a hub doesn’t segment a network, it only allows more hosts on one. Hubs operate at layer one, and is used primarily to physically add more stations to the LAN.B. This also incorrect because the job of a repeater is to repeat a signal so it can exceed distance limitations. It also operates at layer one and provides no means for logical LAN segmentation.F. This is incorrect because media converters work by converting data from a different media type to work with the media of a LAN. It also operates at layer one and provides no means for logical LAN segmentation.A 集线器是不正确的因为不能分段,它只允许许多主机在上面,集线器工作在第一层,它用于首先到自身增加许多位置到局域网B 不正确因为中继器的工作是反复一个信号,因此它能超越远距离限制,它也是工作在一层并且提供无意义的局域网逻辑划分F 它不正确是因为媒体转换工作通过从一个不同的媒体类型转换数据到局域网的其他媒体,它也是工作在1层并提供无意义的局域网划分。
2、Routers perform which of the following functions? (Select three)下列哪些是路由器提供的功能?(选3项)A. Packet switchingB. Collision prevention on a LAN segment.C. Packet filteringD. Broadcast domain enlargementE.

A major function of the router is to route packets between networks.C. Through the use of access lists, routers can permit and deny traffic using layer 3 and layer 4 packet information.F. The primary purpose of a router is to route traffic between different networks, allowing for internetworking.A路由器工作在OSI的3层,主要的功能是在网络中路由数据包C通过使用访问控制列表,通过使用3层和4层的包信息路由器能允许和拒绝传输数据F 路由器的主要目的是在不同网络间的路由传送数据,允许网络错误回答:B. While routers can be used to segment LANs, which will reduce the amount of collisions; it can not prevent all collisions from occurring. As long as there are 2 or more devices on a LAN segment, the possibility of a collision exists, whether a router is used or not.D. The broadcast domain of a LAN is often segmented through the use of a router. This results in reducing the size of the broadcast domain.E. Routers do not forward broadcast traffic.B 路由能够用于局域网的分段,它能减少冲突数量,它不能防止所有的冲突事件,只要在分段中有2个或更多的分段,冲突存在的可能性是是否使用路由D 一个LAN的广播域是通过使用路由器分段,这个结论是减少了广播域的大小 E 路由器不是广播传输数据3、Which of the following statements most accurately describes the characteristics of the above networks broadcast and collision domains? (Select the two best answer choices)如图所示,销售部门和生产部门通过一个路由器分开,下列哪个陈述正确的描述了关于网络广博域和冲突域的特征?A. There are two broadcast domains in the network.B. There are four broadcast domains in the network.C. There are six broadcast domains in the network.D. There are four collision domains in the network.E. There are five collision domains in the network.F. There are seven collision domains in the network.A 网络中有2个广播域B、网络中有4个广播域C、网络中有6个广播域D、网络中有4个冲突域E、网络中有5个冲突域F、网络中有7个冲突域答案:AF解析:In this network we have a hub being used in the Sales department, and a switch being used in the Production department. Based on this, we have two broadcast domains: one for each network being separated by a router. For the collision domains, we have 5 computers and one port for E1 so we have 6 collision domains total because we use a switch in the Production Department so 5 are created there, plus one collision domain for the entire Sales department because a hub is being used.在这个网络中我们有一个集线器用于销售部门,和一个交换机用于生产部门。
基于这些,我们有两个广播域:一个通过一个路由器分开。
对于这冲突域,我们有5台计算机都在E1中因此一共有6个冲突域,因为我们使用了一个交换机在生产部门这样看来有5个在一起,在加上整个销售部门的一个冲突域,因为是用一个集线器连接的4、The Testking corporate LAN consists of one large flat network. You decide to segment this LAN into two separate networks with a router. What will be the affect of this change?局域网是由一个大的网络组成。
你打算将这个网络通过一个路由器分成两部分,这样改变的影响是什么?A. The number of broadcast domains will be decreased.B. It will make the broadcasting of traffic between domains more efficient between segments.C. It will increase the number of collisions.D. It will prevent segment 1’s broadcasts from getting to segment 2.E. It will connect segment 1’s broadcasts to segment 2.A、广播域的数量减少B、使在域中的广播段的传输更有效C、增加冲突域的数目D、防止段1的广播到段2中E、连接段1和段2的广播答案:D解析:A router does not forward broadcast traffic. It therefore breaks up a broadcast domain, reducing unnecessary network traffic. Broadcasts from one segment will not be seen on the other segment.一个路由器不能传输广播,它分解广播域,减少不必要的网络传输。
