Ramesh，s Study Guide(1)-思科认证试题Here is my latest Dump of CCNA exam which i took today with a score of 810.It was quite difficult unlike my expectation. The questions were from from the normal topics except few. However most of these questions were very badly worded Both gramatically and technically to confuse the guys. I think it is deliberately done by Cisco to fail the poor guys and make more money.So Here is Comprehensive Exam Cram for many of you preparing for CCNA. This cram was prepared by myself, quite a lot of hardwork behind this, i am sure you will appreciate it. This is more than enough to pass this exam with a similar score of mine.There are quite lot of short wordings used here only to reduce the time you might take to read this. You will have no problems in understanding this if you have a reasonably good networking knowledge.Ramesh's Study GuideOSI Layers: It allows changes in one layer to occur without changing other layers, It clarifies what general function is to be done rather than how to do it.Application –file, print, message, database, application svcs. identifying communication partners, determining resource availability, and synchng sending & receiving applictns, Eg: SMB, NCP, Telnet, FTP, WWW and SMTP, File Transfer Access and Mangt (FTAM), Virtual Term Proto (VTP), and Common Mangt Info Proto (CMIP).Presentation-Negotiating data xfer Syntax, Data encryption, compression, translation, coding and conversion functions.

CCNA Study Notes1(1)-思科认证试题
CCNA Study Notes1(1)-思科认证试题1. Identify and describe the functions of each of the seven layers of the OSI reference model. Physical LayerThe physical layer defines the electrical, mechanical, procedural, and functional specifications for activating, maintaining, and deactivating the physical link between communicating network systems. Physical layer specifications define such characteristics as voltage levels, timing of voltage changes, physical data rates, maximum transmission distances, and the physical connectors to be used.Data Link LayerThe data link layer provides reliable transit of data across a physical network link. Different data link layer specifications define different network and protocol characteristics, including the following:Physical addressing --Physical addressing (as opposed to network addressing) defines how devices are addressed at the data link layer.Network topology -- Data link layer specifications often define how devices are to be physically connected (such as in a bus or a ring topology).Error notification -- Error notification involves alerting upper layer protocols that a transmission error has occurred.Sequencing of frames --Sequencing of data frames involves the reordering of frames that are transmitted out of sequence.Flow control -- Flow control involves moderating the transmission of data so that the receiving device is not overwhelmed with more traffic than it can handle at one time.The Institute of Electrical and Electronics Engineers (IEEE) has subdivided the data link layer into two sublayers: Logical Link Control (LLC) and Media Access Control (MAC).Network LayerThe network layer provides routing and related functions that allow multiple data links to be combined into an internetwork. This is accomplished by the logical addressing (as opposed to the physical addressing) of devices. The network layer supports both connection-oriented and connectionless service from higher-layer protocols.Transport LayerThe transport layer implements reliable internetwork data transport services that are transparent to upper layers. Transport layer functions typically include the following:Flow control -- Flow control manages data transmission between devices so that the transmitting device does not send more data than the receiving device can process.Multiplexing -- Multi。

思科认证考试题库思科认证考试题库首发网站：1. What are two reasons that a network administrator would use access lists? (Choose two.)A. to control vty access into a routerB. to control broadcast traffic through a routerC. to filter traffic as it passes through a routerD. to filter traffic that originates from the routerE. to replace passwords as a line of defense against security incursionsAnswer: AC解释一下：在VTY线路下应用ACL，可以控制从VTY线路进来的telnet的流量。
也可以过滤穿越一台路由器的流量。
2. A default Frame Relay WAN is classified as what type of physical network?A. point-to-pointB. broadcast multi-accessC. nonbroadcast multi-accessD. nonbroadcast multipointE. broadcast point-to-multipointAnswer: C解释一下：在默认的情况下，帧中继为非广播多路访问链路。
但是也可以通过子接口来修改他的网络的类型。
3．Refer to the exhibit. How many broadcast domains exist in the exhibited topology?A. oneB. twoC. threeD. fourE. fiveF. sixAnswer: C解释一下：广播域的问题，在默认的情况下，每个交换机是不能隔离广播域的，所以在同一个区域的所有交换机都在同一个广播域中，但是为了减少广播的危害，将广播限制在一个更小的范围，有了VLAN的概念，VLAN表示的是一个虚拟的局域网，而他的作用就是隔离广播。
