Introduction Welcome to CCENT Exam Cram! The materials in this book have been prepared with a very clear focus on testable concepts, configurations, and skills. As much extraneous material as possible, beyond what is needed for background comprehension, has been eliminated so that the book is a distillation of the necessary knowledge to take—and pass—the Cisco CCENT exam.
The two sample tests with answer keys at the end of the book should give you a reasonably accurate assessment of your knowledge. We have also included labs to give you the critical hands-on practice you will need to master the simulator questions on the CCENT exam. Exam Cram books help you understand and appreciate the subjects and materials you need to pass Cisco certification exams. Exam Cram books are aimed strictly at test preparation and review. They do not teach you everything there is to know about a topic. Nevertheless, to completely prepare yourself for any Cisco test, we recommend that you begin by taking the Self-Assessment that is included in this book, immediately following this introduction.
The Self-Assessment tool will help you evaluate your knowledge base against the requirements for a CCENT under both ideal and realistic circumstances. Based on what you learn from the Self-Assessment, you might decide to begin your studies with some classroom training, some practice with the Cisco IOS, or some background reading. On the other hand, you might decide to pick up and read one of the many study guides available from Cisco or third-party vendors on certain topics, including the CCNA Exam Prep from Que Publishing. We also recommend that you supplement your study program with visits to www. Book learning is essential, but without a doubt, hands-on experience is the best teacher of all! This book includes a CD that you can use to practice your skills. Passing the ICND1 exam certifies you as CCENT; subsequently passing the ICND2 exam certifies you as CCNA. In the United States and Canada, tests are administered by VUE.
You can contact VUE at www. To sign up for a test, you must either possess a valid credit card or contact VUE for mailing instructions to send a check in the United States. Only when payment is verified or your check has cleared can you actually register for the test. To schedule an exam, you need to call the number or visit the web page at least one day in advance. To cancel or reschedule an exam, you must call before 7 p. When you want to schedule a test, you should have the following information ready:. Your name, organization, and mailing address. Your Cisco test ID. The name and number of the exam you want to take. A method of payment As mentioned previously, a credit card is the most convenient method, but alternative means can be arranged in advance, if necessary.
After you sign up for a test, you are told when and where the test is scheduled. You should try to arrive at least 15 minutes early. You must supply two forms of identification—one of which must be a photo ID—and sign a nondisclosure agreement before you will be admitted into the testing room. In fact, you are not permitted to take anything with you into the testing area, but you are given a blank sheet of paper and a pen or in some cases, an erasable plastic sheet and an erasable pen. In Exam Cram 2 books, this information appears on a tear-out sheet inside the front cover of each book. You are given some time to compose yourself, record this information, and take a sample orientation exam before you begin the real thing. NOTE If you fail a Cisco test, you must wait five full days before you can take it again.
For example, if you failed on Tuesday, you would have to wait until Monday to take it again. Tracking Your Certification Status As soon as you pass the Cisco CCNA single exam, or both the ICND1 and ICND2 tests, you are a CCNA. Passing the ICND1 test certifies you as CCENT, the new entry-level Cisco networker certification. Cisco generates transcripts that indicate which exams you have passed. You can view a copy of your transcript at any time by going to the Cisco website and going to the certifications tracking tool. This tool enables you to print a copy of your current transcript and confirm your certification status. After you pass the necessary set of exams, you are certified.
The package for official certification that arrives includes. A certificate that is suitable for framing, along with a wallet card. A license to use the applicable logo, which means that you can use the logo in advertisements, promotions, and documents, as well as on letterhead, business cards, and so on. Along with the license comes information on how to legally and appropriately use the logos. As an official recognition of hard work and broad knowledge, one of the Cisco credentials is a badge of honor in many IT organizations. The following list of materials can help you study and prepare:. The official Cisco study guides by Cisco Press. Practicing with real equipment or simulators. The CCNA Prep Center at Cisco. com, which features articles, sample questions, games, and discussions to focus and clarify your studies. The exam-preparation advice, practice tests, questions of the day, and discussion groups on the www. com e-learning and certification destination website.
The CCENT Exam Cram—This book gives you information about the material you need to know to pass the tests. Seriously, this is a great book. The CCNA Exam Prep book, also from Que publishing, goes into more detail on topics that are summarized in the Exam Cram. Together, these two books make a perfect pair. These companies aim to help you prepare to pass the CCENT and CCNA exams. Although such training can be expensive, most of the individuals lucky enough to partake find this training to be very worthwhile. What This Book Will Not Do This book will not teach you everything you need to know about networking with Cisco devices, or even about a given topic.
Nor is this book an introduction to computer technology. com, where you will find a whole section dedicated to Cisco certifications and networking in general. This book will review what you need to know before you take the test, with the fundamental purpose dedicated to reviewing the information needed on the Cisco CCENT exam. Again, it is not a comprehensive treatise on Cisco networking. What This Book Is Designed to Do This book is designed to be read as a pointer to the areas of knowledge you will be tested on.
In other words, you might want to read the book one time, just to get an insight into how comprehensive your knowledge of networking with Cisco is. The book is also designed to be read shortly before you go for the actual test and to give you a distillation of the entire field of CCENT knowledge in as few pages as possible. We think you can use this book to get a sense of the underlying context of any topic in the chapters—or to skim read for Exam Alerts, bulleted points, summaries, and topic headings.
Our aim is to walk you through the knowledge you will need—looking over your shoulder, so to speak—and point out those things that are important for the exam Exam Alerts, practice questions, and so on. The CCENT exam makes a basic assumption that you already have a strong background of experience with the general networking and its terminology. Therefore, the topics covered in later chapters might refer to previous discussions in earlier chapters. We suggest that you read this book from front to back. Chapter Formats Each Exam Cram chapter follows a regular structure, along with graphical cues about especially important or useful material. The structure of a typical chapter is as follows:.
We follow the hotlists with a few introductory paragraphs, setting the stage for the rest of the chapter. Alerts—Throughout the topical coverage section, we highlight material most likely to appear on the exam by using a special Exam Alert layout that looks like this: EXAM ALERT This is what an Exam Alert looks like. An Exam Alert stresses concepts, terms, or activities that will most likely appear in one or more certification exam questions. For that reason, we think any information found offset in Exam Alert format is worthy of unusual attentiveness on your part. What appears in the chapter content is critical knowledge. Notes—This book is an overall examination of basic Cisco networking. Where a body of knowledge is deeper than the scope of the book, we use notes to indicate areas of concern or specialty training, or refer you to other resources. Tips—We provide tips that will help you to build a better foundation of knowledge or to focus your attention on an important concept that will reappear later in the book.
Tips provide a helpful way to remind you of the context surrounding a particular area of a topic under discussion. Practice questions—This section presents a short list of test questions related to the specific chapter topic. Each question has a following explanation of both correct and incorrect answers. The practice questions highlight the areas we found to be most important on the exam. The bulk of the book follows this chapter structure, but there are a few other elements that we would like to point out:. Sample tests—The sample tests are very close approximations of the types of questions you are likely to see on the current CCENT exam.
Answer keys—These provide the answers to the sample tests, complete with explanations of both the correct responses and the incorrect responses. Glossary—This is an extensive glossary of important terms used in this book. Cram Sheet—This appears as a tearaway sheet inside the front cover of this Exam Cram book. It is a valuable tool that represents a collection of the most difficult-to-remember facts and numbers we think you should memorize before taking the test. Remember, you can dump this information out of your head onto a piece of paper as soon as you enter 8 CCENT Exam Cram Exam the testing room. You need to remember this information long enough to write it down when you walk into the test room. Be advised that you will be asked to surrender all personal belongings before you enter the exam room itself. You might want to look at the Cram Sheet in your car not while you are driving—can you believe we have to point this out?
or in the lobby of the testing center just before you walk into the testing center. The Cram Sheet is divided under headings, so you can review the appropriate parts just before each test. CD—The CD features an innovative practice test engine powered by MeasureUp, including over practice questions. The practice exam contains both multiple choice and simulation question types covering all the objectives on the CCENT ICND1 exam, providing you with a challenging and realistic exam simulation environment. You can reach us via email at [email protected] and [email protected] Let us know if you found this book to be helpful in your preparation efforts. Thanks for choosing us as your personal trainers, and enjoy the book. Self-Assessment This section helps you to determine your readiness for the CCENT certification exam.
You will be invited to assess your own skills, motivations, education, and experience and see how you compare against the thousands of CCENT candidates we have met. TIP You can also pre-assess your CCENT readiness by using the accompanying CD. In the past few years, Cisco has added router and switch simulators to computer-based tests to test the applied knowledge of candidates, and we can expect this trend to continue. A Cisco certification is still the gold standard for networking professionals. A mastery of technical knowledge—Knowing your stuff is essential, and you must maintain an elevated level of retention and accuracy. The CCNA exam has a pass mark of out of 1, Very little room for technical error exists. Successful candidates know their stuff. A demonstrated ability to apply the technical knowledge—The addition of simulator questions has greatly 10 CCENT Exam Cram Exam reduced the possibility that a candidate can simply memorize all the information and pass the exam.
A CCNA is supposed to be able to apply basic router and switch configurations; the simulator questions help prove that the candidate can do so. Many candidates find that they have little time left when they finish, and indeed many run out of time altogether— and some fail as a result. All of this is intimidating—and unfortunate for the unprepared—so be prepared. In response to feedback from the industry, Cisco has introduced the new Cisco Certified Entry Networking Technician CCENT certification. The CCENT is effectively the first half of CCNA; passing the ICND1 exam certifies you as CCENT, and subsequently passing ICND2 certifies you as CCNA. This graduated approach provides the benefit of a meaningful certification at an entry level while reflecting the nature of CCNA as having evolved into an intermediate instead of introductory certification.
However, the requirements and expectations of a CCENT are not so different from those of a CCNA, and the expectation is that a CCENT will move on to CCNA within a short time. Imagine yourself as an employer looking for a junior networking professional. You want someone who knows their stuff, who can reliably do the actual work of setting up and configuring equipment, and who can do all that under the pressures of time, screaming bosses and customers, and critical deadlines. A combination of skills and experience is the short answer. The successful candidates we have seen—and we have seen thousands from classes that we have taught—had a good mix of the following traits:.
Motivation—Why are you taking the CCENT or CCNA? Here are some of the most common answers to this question that we have seen:. Because I want to further my career and get a promotion. My job is changing, and the company needs me to get the certification. The company needs more Cisco-certified people to gain a certain part- ner status as a reseller. So what motivates you? Who is paying for the training and exams? What are the implications if you fail? Successful candidates are highly motivated. Candidates who have acquired the skills to do this—and rest assured, these are skills that can be learned—will do better than those who have trouble retaining information. Candidates who simply enjoy learning will find it easier and will do better as a result. This book is not aimed at teaching you these skills; other books are. In the absence of the ability to learn and retain quickly, patience and persistence are a good substitute.
If it takes you a year to pass, you have still passed. We have seen candidates with little experience succeed and candidates with extensive experience fail. Experience is not a guarantee, but it absolutely helps. As a guideline, if you have been involved with business-class networks for about a year, you will probably have absorbed enough knowledge to give you an advantage when it comes to the basics. Maybe you know someone who can help you with an objective assessment—a friend, a teacher, or an HR person perhaps. Above all, realize that the following questions and comments simply summarize our experience with CCNA candidates. That experience is pretty solid; we have taught CCNA to more than a thousand people.
By the same token, though, there is no magic formula; every person is a different story. Your best plan is to be as prepared as you can be in all respects. Educational background forms a big part of this preparation. These questions will help to identify education and training that will be of benefit: 1. Have you ever taken any computer science courses at a college level? Most college-level IT courses include an element of networking theory. Also, if you are taking this kind of course, you are probably already interested in this topic and will find it easier to master the basics and pick up the advanced stuff. If you have never taken an IT course at this level, you have a steeper learning curve and might be at a disadvantage. Did you attend college and major in a computer-related field? If so, you should have most of the basics covered—unless you studied programming; in which case, you might not have covered much in the way of networking. Some colleges actually offer the CCNA as part of the curriculum.
Doing a college major in IT is not a prerequisite by any means, but it might be helpful. Have you ever held an IT certification? If you have been certified before, you have some idea of what is coming in terms of the depth of knowledge required and the examination process; it also implies at least some involvement in computers and networking. Which certification s have you held? A previous CCNA will definitely be an asset—but not a guarantee. The CCNA has changed dramatically in the past several years. Do you currently hold any IT certifications? Current information is more relevant, especially in the IT world. Some certifications are more relevant than others, of course, as noted previously. Which certification s do you currently hold? You might hold other Cisco specialization certs, or current certs from Microsoft, CompTia, or Novell. Again, anything that has tested your networking knowledge will be an asset. Have you ever taken any IT training courses in networking?
Many people take training courses but do not certify. Any exposure and knowledge gained from these courses will be useful. How much self-study have you done? The fact that you are holding this book is a very good sign. Read all of it! This is a tricky equation. The longer you study, the more you are likely to know—but the more you are likely to forget, as well. Is there a formal or informal training plan for you at your workplace? Work experience is a great way to gain the knowledge and skills you need for the exam. A training plan can be a good motivator because you might have someone coaching and encouraging you and also because there may be a reward—perhaps a promotion or raise—for completing the program. The new simulator questions require you to actually type in router configurations. Ask yourself the following: 1. Does your job allow you to work with Cisco routers and switches on a regular basis? Is there a lab where you can practice?
Perhaps at home with borrowed or purchased gear? How long have you been working with Cisco equipment? Are you completely fluent in subnetting? At a minimum, you should get a simulator that includes lab exercises for you to practice key skills. If you have access to a lab and equipment you can play with, as you become more advanced, you can build more complicated and realistic test networks. The major skill areas you need hands-on experience in are. Basic configuration: IP addresses, passwords. Dynamic routing protocol configuration. Basic WAN protocols and configuration. Switching, VLANs, VLAN Trunking Protocol, Trunking. IP Access Lists As you think about those areas, picture yourself in front of a Cisco router and assess your level of confidence in being able to quickly and correctly configure it. You should feel no intimidation or uncertainty in being able to tackle these kinds of configurations. Subnetting in particular is heavily emphasized and is one of the main areas where people have difficulty.
You must be totally, unequivocally confident with subnetting or you will face a serious challenge on your exam. You can give yourself experience in this environment by practicing on an exam simulator until you are comfortable. This can be achieved by repetition, but be careful that you do not simply memorize all the questions in the test pool! Technical excellence is achieved with study, training, and self-testing. Applied skills are learned through practice labs and exams, work experience, and hands-on training and experience. The ability to perform under pressure is gained from situational training, such as exam simulators and challenge labs, perhaps with a trainer or mentor.
The goal is to increase your confidence level so that you feel as if you own the material and want to be challenged to a duel by the exam. Good luck; study hard. This chapter introduces the basics of networking and points out some of the concepts that are tested on the CCNA exam s. Components and Terms A network is a set of devices, software, and cables that enables the exchange of information between them. Host devices are computers, servers, laptops, Personal Digital Assistants PDAs , or anything a person uses to access the network. Network devices are hubs, repeaters, bridges, switches, routers, and firewalls to name a few. There are thousands of networkable applications; we are concerned with a small number of them. Topologies A topology describes the layout of a network. You need to know several topologies for the exam. Serial communication is usually point-to-point, but not always. In a star topology, if a host wants to send to another host, it must send traffic through the hub or central device.
Ethernet, if using a hub or a switch and Twisted Pair cabling, is star-wired. FDDI and Token Ring are examples of ring topologies. The term bus comes from an electrical bus, which is a point from which electrical power can be drawn for multiple connections. Ethernet that uses coaxial cable creates a bus topology. The advantage is that you can send data directly from any location to any other location instead of having to send it through a central point. There are more options for sending if one of the connections fails. The disadvantages are that it is expensive and complex to implement a full mesh.
You can compromise and build a partial mesh, which is when only some locations are connected to the other locations. LAN Technologies LAN stands for local area network. LANs are short-range, high-speed networks typically found in schools, offices, and, more recently, homes. Over the years, there have been many types of LANs. Currently, Ethernet is king, and other than wireless technologies, it is the only LAN technology you need to know for the CCNA exam. Ethernet Ethernet is the most common LAN technology in use today. Ethernet is a family of implementations, which have evolved into faster and more reliable solutions all based on a common technology. Ethernet was pioneered by Digital Equipment Corporation, Intel, and Xerox and first published in The IEEE modified it and gave it the specification The way Ethernet works is closely linked to its original connection type: A coaxial cable was used to join all the hosts together.
This formed a segment. On a single segment, only one host could use the cable at a time; because the wire was coaxial, with one positive conductor and one negative conductor, it created a single electrical circuit. This single circuit could be energized by only one host at a time, or a conflict would result as two hosts tried to talk at once and nothing got through. Much the same thing happens when you and a friend try to send at the same time using walkie-talkies; all that is heard is noise. This conflict is called a collision. When a host wants to transmit, it 20 Chapter 1: Networking Fundamentals first listens to the wire to see if anyone else is transmitting at that moment. If it is clear, it can transmit; if not, it will wait for the host that is transmitting to stop. Sometimes, two hosts decide at the same instant that the wire is clear, and collide with each other. When this happens, the hosts that were involved with the collision send a special jam signal that advises everyone on that segment of the collision.
Then all the hosts wait for a random period of time before they check the wire and try transmitting again. This wait time is tiny—a few millionths of a second—and is determined by the backoff algorithm. The backoff algorithm is the mathematical equation a host runs to come up with the random number. The theory is that if each host waits a different amount of time, the wire should be clear for all of them when they decide to transmit again. Any Ethernet segment that uses coaxial cable BASE 2, BASE 5 or a hub with twisted-pair cabling is a collision environment. EXAM ALERT When a collision occurs 1. A Jam Signal is sent. All hosts briefly stop transmitting. All hosts run the backoff algorithm, which decides the random time they will wait before attempting to transmit again. Collisions have the effect of clogging up a network because they prevent data from being sent.
The more hosts you have sharing a wire, and the more data they have to send, the worse it gets. As networks grew, it became necessary to break up collision domains so that there were fewer collisions in each one. This requires four conductors—a positive and negative pair for each circuit. The use of twisted-pair cabling not coax , which has at least four conductors and more likely eight allows us to create a full duplex connection, with simultaneous send and receive circuits. Full-duplex connections eliminate collisions because the host can now send and receive simultaneously.
Modern Ethernet is fast, reliable, and collision free if you set it up right. Speeds of up to 10 gigabits per second are possible with the correct cabling. This is not all of them, just an idea of how far Ethernet has come. TABLE 1. WAN Technologies A wide area network WAN serves to interconnect two or more LANs. WAN technology is designed to extend network connectivity to much greater distances than any LAN technology is capable of. Service providers are in the business of building and selling WAN connectivity; they invest in the equipment, cabling, and training to build transcontinental networks for other businesses to rent. For the CCNA exam, you need to be familiar 22 Chapter 1: Networking Fundamentals with four types of WAN connections and the protocols associated with them.
Dedicated Leased Line Connections A leased line refers to a connection that is installed and provisioned for the exclusive use of the customer. This is good because no other customer can affect your line, as can be the case with other WAN services. You have a lot of control over this circuit to do things such as Quality of Service and other traffic management. The downside is that a leased line is expensive and gets a lot more expensive if you need to connect offices that are far apart. A leased line is typically a point-to-point connection from the head office to a branch office, so if you need to connect to multiple locations, you need multiple leased lines.
Multiple leased lines get even more expensive. Leased-line circuits typically run the Point-to-Point Protocol PPP , High-Level Data-Link Control Protocol HDLC , or possibly Serial Line Internet Protocol SLIP. These protocols are covered in detail in Chapter Circuit-Switched Connections A circuit-switched WAN uses the phone company as the service provider, either with analog dial-up or digital ISDN connections. With circuit-switching, if you need to connect to the remote LAN, a call is dialed and a circuit is established; the data is sent across the circuit, and the circuit is taken down when it is no longer needed. Circuit-switched WANs usually use PPP, HDLC, or SLIP, and they tend to be really slow—anywhere from They can also get expensive because most contracts specify a pay-per-usage billing. This can be an issue sometimes, but it can be managed. So if you have a lot of branch offices and they are far away from the head office, a packet-switched solution is a good idea.
Packet-switched circuits usually use Frame Relay or possibly X. Cell-Switched Connections Cell switching is similar to packet switching; the difference is that with packetswitched networks, the size of the units of data being sent called frames is variable. Cell-switched units cells are of a constant size. This makes dealing with heavy traffic loads easier and more efficient. Cell-switched solutions such as Asynchronous Transfer Mode ATM tend to be big, fast, and robust. Wireless Networks There has been a boom recently in the deployment of wireless networks for both LAN and WAN applications. The IEEE The advantages are the elimination of cables and the freedom of movement; the disadvantages are in range, reliability, and security. Wireless is a good WAN choice for moderate distances less than 10 miles, for example with line-of-sight between them—for example, between buildings in a campus. Special antennas are used to make the wireless signal directional and increase the range, often to more than 20 kilometers.
This service is typically found only in urban business centers where large corporations need high bandwidth, hence the metro name. This is a very high-speed, medium- range system that allows a server or cluster of servers to access an external disk storage array as if it were a locally connected hard drive. Content networks deal with making access to the information faster, as well as logging and controlling access to certain kinds of material. However, these specialized network types are beyond the scope of CCNA. Your boss asks you to explain what happens when a collision occurs on an Ethernet segment. Which of the following are accurate? Choose 3. Every device stops transmitting for a short time. When it is safe to transmit again, the devices that collided get priority access to the wire.
The collision starts a random backoff algorithm. A jam signal is sent to alert all devices of the collision. Only the devices involved in the collision stop transmitting briefly to clear the wire. How is equal access to the wire managed in a collision-oriented environment such as Ethernet? The hosts are given equal access based on the circulation of a token; hosts can only transmit when they hold the token. Hosts are given prioritized access to the wire based on their MAC address. Hosts are given equal access to the wire by being allowed to transmit at specified time intervals.
Hosts signal their desire to transmit by sending a contention alert. Hosts check the wire for activity before attempting to send; if a collision happens, they wait a random time period before attempting to send again. Which of the following are commonly used WAN protocols? PPP 26 Chapter 1: Networking Fundamentals 4. Which of the following are IEEE specifications for Gigabit Ethernet? Choose 2. Which technology is cell-switched? PPP 6. Which devices were designed to segment collision domains? Switch 7. You have just acquired some new office space in a building across the street from your current space, about meters away. You want to arrange for high-speed 10Mbs network connectivity between them; which of the following choices is a valid connection option?
