This route is already part of the initial configurations we provided for you.j. Also, one of the problems in this lab can be solved with multiple frame map ip statements, but that is not the solution we want you to use, Solve the problem with routing, not layer 3 to layer 2 mapping via additional frame map statements!!!(Yes, this is a tricky issue)You have completed lab 1. compare your configurations to the ones we provided. Often there is more than one complete a task so your configurations may be different than ours. If your configuration are different than ours make sure you understand how to complete the lab with our configurations too.Lab 2At the end of this lab verify connectivity to all ports.

A.0C.110D.120正确答案：D有两台运行RSTPPVST＋的交换机,它们之间有4条连接,你想在不牺牲RSTP提供的弹性的情况下提高带宽。
为此,除已提供的默认配置外,你可在这两台交换机之间配置什么?( )6、A.配置PortFast和BPDU防护，以提高会聚速度B.给RSTP PVST+配置非等成本负载均衡C.将全部4条链路捆绑为一条EtherChannelD.配置PPP并使用多链路答案：C7、You are working as a network technician at Ezonexam University, when you get a call from the Engineering Faculty. They’re complaining that they’re receiving obsolete information from the Business Faculty’s network traffic broadcasts.What can you do to contain the Business Faculty’s broadcast while still keeping it connected to the internet and the enterprise services of the University? (Select all valid answer choices)A. Use half and full-duplex Ethernet on the Engineering Department LANB. Establish a VTP domain to minimize the obsolete trafficC. Change the switch IP address of the switchD. Create separate VLANs and subnets for the two departments and route between the twoE. Provide greater bandwidth to the Engineering Department LANF. Place the business department on a separate subnet and route between networks正确答案：DFD,F 解析：Explanation:In order to prevent the broadcast and link level multicast traffic separated between the departments, they need to be isolated at layer two. This can be accomplished in two ways. The first is to create separate VLANs and place each department into a different one. The second method would be to separate the two departments into two completely different networks, and route between them.Incorrect Answers:A. Mixing the use of half and full duplex will make no difference to the number of broadcasts sent.B. Trunking is only useful in networks that already contain VLANs.C. This will make no difference, as all users will still be contained within the same IP subnet.E. The amount of bandwidth involved will not have any impact on the amount of broadcasts that are sent and received.思科为何要开发专用的STP和RSTP扩展PVST＋?( )8、A.通过优化根网桥的配置，提高会聚速度、优化数据流传输路径B.通过优化非根网桥的配置，提高会聚速度、优化数据流传输路径C.PVST+使得能够更迅速地丢弃非IP帧D.PVST+实际上是IEEE标准802.1w答案：A9、Which fields are included in the TCP header? (Choose three).A. Source PortB. Acknowledgement NumberC. Request NumberD. Destination AddressE. WindowF. Data正确答案：ABEA,B,E 解析：Explanation:TCPheader:Sourc e Port: 16 bits.Destination Port: 16 bits.Sequence Number: 32 bits.The sequence number of the first data byte in this segment. If the SYN bit is set, the sequence number is the initial sequence number and the first data byte is initial sequence number + 1.Acknowledgment Number: 32 bits.If the ACK bit is set, this field contains the value of the next sequence number the sender of the segment is expecting to receive. Once a connection is established this is always sent.Data Offset: 4 bits.The number of 32-bit words in the TCP header. This indicates where the data begins. The length of the TCP header is always a multiple of 32 bits.Reserved: 3 bits.Must be cleared to zero.ECN, Explicit Congestion Notification: 3 bits.Added in RFC 3168.Control Bits: 6 bits.Window: 16 bits, unsigned.The number of data bytes beginning with the one indicated in the acknowledgment field which the sender of this segment is willing to accept.Checksum: 16 bits.This is computed as the 16-bit one’s complement of the one’s complement sum of a pseudo header of information from the IP header, the TCP header, and the data, padded as needed with zero bytes at the end to make a multiple of two bytes.Urgent Pointer: 16 bits, unsigned.If the URG bit is set, this field points to the sequence number of the last byte in a sequence of urgent data.Options: 0 to 44 bytes.Options occupy space at the end of the TCP header. All options are included in the checksum. An option may begin on any byte boundary. The TCP header must be padded with zeros to make the header length a multiple of 32 bits.Data: Variable length.10、You need subnet a Ezonexam network segment. How many subnetworks and hosts are available per subnet if you apply a /28 mask to the 210.10.2.0 class C network?A. 30 networks and 6 hosts.B. 6 networks and 30 hosts.C. 8 networks and 32 hosts.D. 32 networks and 18 hosts.E. 16 networks and 14 hosts.F. None of the above正确答案：EE 解析：Explanation:A 28 bit subnet mask (11111111.11111111.11111111.11110000) applied to a class C network uses a 4 bits for networks, and leaves 4 bits for hosts. Using the 2n-2 formula, we have 24-2 (or 2x2x2x2-2) which gives us 14 for the number of hosts, and the number of networks is 24 = 16.Incorrect Answers:A. This would be the result of a /29 (255.255.255.248) network.B. This would be the result of a /27 (255.255.255.224) network.C. This is not possible, as we must subtract two from the subnets and hosts for the network and broadcast addresses.D. This is not a possible combination of networks and hosts.11、Show cdp interface命令是用于显示以下哪一项的（）A.CDP的时间值和接口状态B.邻居路由器的接口配置C.邻居设备的IP地址D.CDP保持时间正确答案：A12、哪个命令用来设置Cisco设备串行接口的默认封装( )A.Router(config)encapsulation hdlcB.Router(config)encapsulation default hdlcC.Router(config-if)encapsulation hdlcD.Router(config-if)encapsulation ppp正确答案：C13、下图中如果允许192.168.1.0/24和10.0.0.0/8的网络之间通信，必须要配置的两条命令是什么( )A.A(config)iproute 10.0.0.0 255.0.0.0 172.16.40.2B.A(config)iproute 10.0.0.0 255.0.0.0 S0/0/0C.A(config)iproute 10.0.0.0 255.0.0.0 10.0.0.1D.B(config)iproute 192.168.1.0 255.255.255.0 172.16.40.1E.B(config)iproute 192.168.1.0 255.255.255.0 172.16.40.2F.Biproute 192.168.1.0 255.255.255.0 192.168.1.1正确答案：AD14、在启用IGRP协议时，所需要的参数是：( )A.网络掩码B.子网号C.自治系统号D.跳数正确答案：C15、请参见图示。

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。

R&S CCIE Practice Lab 1 Version2.00 1-day VersionAt the end of this lab verify connectivity to all ports. You should be able to ping every interface form any router. (don’t worry about being able to ping a local frame-relay interface. Please disregard this statement if you are asked to filter packets, routers or other specific tasks.)1. Initial Configuration –5 pts (30 minutes)a. Use the pre-configuration files to apply proper IP addresses to the router interfaces. Add IP addresses as needed as shown on the network diagram.b. Configure router R7 as a frame-relay switch. Refer to the diagram for interface connections to other routers connected to router R7.c. Connect routers R1,R2, R3, and R5 over the frame-relay cloud. Configure router R1’s S0 interface as a sub-interface. Configure R2,R3, and R5 without using sub-interfaces. Use only one frame-relay PVC on routers R2, R3, and R5. The recommended DLCI numbers 102, 201,103,301,105, and 501 are indicated on the lab diagram.d. Routers R1, R2, R3, and R5 should share network 10.10.x.x 255.255.0.0 on their frame-relay interfaces.e. Router R1 should have network 10.1.x.x with an 8-bit subnet mask on its Ethernet interface( The mask should be 255.255.0.0)f. Make sure all the Ethernet interfaces are in their own broadcast domain if you are using an Ethernet switch for your Ethernet connections.2. OSPF Configuration –25pts (2 hours 30 minutes)a. configure OSPF area 0 on the frame-relay interfaces between R1, R2, R3, and R5.b. Configure router R1’s interface Ethernet 0 for OSPF area 1c.
