Four information-packed books in one comprehensive package tohelp networking newcomers prepare for Ciscos CCENTcertification! If youre preparing for your. The CCENT certification is a new, fast-growing certification that tests your knowledge of basic Cisco device-management and networking concepts. It is a great. CCENT Certification All-in-One For Dummies is really four books-in-one: Networking Basics, Cisco Device Basics, Routing and Switching, and Advanced Topics.

Secure Communication: To remotely manage the device, use SSH instead of telnet as the communication is encrypted.

The following are some key points to remember about network cabling. Rollover cable: A rollover cable is also known as a console cable and gets the name rollover because the order of the wires from one end of the cable to the other are totally reversed, or rolled over.

Back-to-back serial cable: The back-to-back serial cable is used to connect two Cisco routers directly together over a serial link. A back-to-back serial link will have one router act as the DCE device with the clock rate set and the other router act as the DTE device.

Straight-through cable: A straight-through cable is used to connect dissimilar devices together. Scenarios that use straight-through cables are computer-to-switch and switch-to-router.

Crossover cable: A crossover cable has wires 1 and 2 switch positions with wires 3 and 6 on one end and is used to connect similar devices together. Scenarios that use crossover cables are computer-to-computer, switch-to-switch, and computer-to-router they are both hosts.

Coaxial cable: A network cable type used in old Ethernet environments, such as 10Base2 and 10Base5. Coaxial cable is seen in high-speed Internet connections with cable companies today. Fiber optic cable: A unique cable type that has a glass core which carries pulses of light as opposed to copper cable carrying electrical signals coax and twisted pair cabling.

The following are some key points to remember about devices and services: Network devices Hub: A hub is a layer-1 device that is used to connect systems together. When a hub receives data in the form of an electrical signal, it sends the data to all other ports in hopes the destination system is at one of those ports.

All ports on the hub create a single collision domain and a single broadcast domain. Repeater: A repeater is a layer-1 device that is used to amplify the signal. As the signal travels along the network, it gets weaker due to interference, so the purpose of the repeater is to regenerate that signal so it can travel more distance.

Bridge: A bridge is a layer-2 device that creates multiple network segments. The bridge maintains a table in memory of what systems reside on what segments by their MAC addresses. When data reaches the bridge, the bridge filters the traffic by only sending the data to the network segment that the destination system resides on. The purpose of the bridge is that it filters traffic by sending the data only to the segment where the destination system resides.

Each segment on the bridge creates a separate collision domain, but it is all one broadcast domain. Switch: The switch, another layer-2 device, is an improvement on a bridge in the sense that each port on the switch acts as a network segment.

This is very useful when you are preparing for the exam; it can help you make sure that you know each point in the objectives. Online Cheatsheet To help you prepare for the CCENT certification exam, and to give you a quick listing of commands for the real world, I have created an online cheatsheet that is designed to give you some of the core facts to remember for the exam.

Be sure to read and understand this book, but the online resource is there as a good refresher.

If you are reading this book, you have most likely decided that you are interested in furthering your career in networking by attaining your first Cisco certification — the Cisco Certified Entry Networking Technician CCENT. I have to say that the CCENT certification is one of my favorite certifications because though it is considered an entry-level certification it ensures the exam candidate has basic networking knowledge and knows the fundamentals of Cisco device configuration.

This chapter is designed to give you information on what to expect on the CCENT certification exam and how to go about registering for it.

Study hard and good luck! This has changed in recent years, and now the first Cisco certification that certification candidates work toward is the CCENT. The reason for the change is that the CCNA exam topics that are now covered have expanded to the point that someone new to Cisco networking would find it very difficult to know the details of all the exam topics — so the CCNA was broken into two different exams.

Cisco decided to provide two options for someone looking to obtain a CCNA. Cisco has many different certification paths that IT professionals can take, such as the Routing and Switching path, Security path, and Wireless path.

The CCENT certification is the first certification exam in all the Cisco certification paths and, as a result, has become a very popular certification. Obtaining the CCENT certification is your way of proving to employers and customers that you have the skills to manage Cisco devices in a small network environment. You can schedule your exam appointment at any VUE testing center by calling one of the following phone numbers or by scheduling it online at www.

Pearson VUE is a company that provides computer-based testing and certification exams and is the testing provider selected by Cisco for the Cisco certification exams. The exam is approximately 90 minutes in length, and you will be presented with 40 to 50 questions. The exam is available in a number of different languages, such as English, Japanese, Chinese, and French — to name just a few.

If for some reason you do not pass the exam, Cisco requires that you wait six days before retaking the exam five days from the day after your last exam.

After passing the CCENT certification exam, the certification is valid for three years, at which point you will need to renew it.

Adaptive exams are shorter exams as they move on to the next topic once you answer a question in a topic area correctly — this is not the case with the CCENT certification exam! Also note that Cisco does not publish the passing score and scoring details as they are subject to change.

This means knowing what to expect on the exam as far as the technical content you need to know and the style of questions on the exam.

Each style of question is designed to test you in a different way. For example, the multiple-choice questions are designed to test your knowledge level the theory , while the simulation questions will test your hands-on skills — ensuring you can perform the task.

You are required to select the best answer from the list of choices. For example, you may be given a list of definitions on the right side of the screen and you need to drop the correct term onto the proper definition. You will first be presented with a scenario and then you will be given four or five multiple-choice questions to answer for that scenario.

The difference is that the scenario is in the form of a simulation. With a simlet, you are asked multiple questions and, in order to answer the questions, you will need to use router commands to view the configuration of the router in the simulator. With a simulation, you are given a number of tasks that need to be performed in the simulator and you are graded on how you do with your configuration within the simulation.

It is very important that you get familiar with how to answer each of the question types discussed above. This exam tutorial shows you what each of the question types look like as well as how you go about answering the questions. The URL for the exam tutorial is www. When you actually begin your exam on test day, Cisco will ask if you would like to take the exam tutorial. I highly recommend doing the exam tutorial as it will give you a chance to see how to use the test engine.

It only takes a few minutes to do the tutorial, and the time does not come off your exam time. Again, you want to be as prepared as possible! One last point to make about the exam questions is that you cannot mark questions and go back to them at a later time like you can with Microsoft or CompTIA exams.

Once you have answered a question, you cannot change the answer after moving on to the next question. Also note that it is best to select an answer to a question even if you do not know the answer because you are unable to go back to the question at a later time.

The following is a list of the major exam objectives that you will be tested on, with a quick description of that objective. This objective is designed to test your knowledge of basic networking concepts, and it includes an understanding of the OSI model, the different types of networking devices, and the pathway of communication on a network. This objective tests your knowledge of the different types of connectors that exist on Cisco switches and the basic concepts of Cisco switches.

You will also be tested on configuration tasks such as disabling ports and configuring port security on a switch.

You are also tested on IP addressing and troubleshooting communication problems that are due to IP addressing issues. In this objective, you are tested on the basic configuration of a router and the routing process.

You are required to know how to implement static routing and dynamic routing using the RIP and RIPv2 routing protocols. This objective is also designed to cover tasks such as backing up your router configuration. This objective is designed to test you on basic wireless terminology and security protocols surrounding wireless.

CCENT Certification All-In-One For Dummies

This objective tests you on basic security principles with networks and networking equipment. You are also tested on best practices with router configuration and location of equipment. The last objective tests you on basic WAN terminology and configuration of a serial link on a Cisco router. When you have finished your exam, you will get a printout indicating your score and whether you have passed or failed.

The exam results printout also gives you your score as a percentage of the objectives listed above. This lets you know what areas you need to work on to improve your knowledge when working with Cisco devices.

Ccent Books

It is important to make sure that after reading a chapter, you spend some time on an actual Cisco device or in a simulator practicing the topics covered in that chapter. You can download simulators from many different Web sites for a fee; for example, you can download the Network simulator for CCENT from www.

The best way to use this book to prepare for the exam is to first read a chapter, starting with the Quick Assessments section, to determine how much you know about the topic before you start reading.

Then, read the chapter again — but this time, spend some time trying out the commands that are discussed in the chapter. After practicing the commands as you read through the chapter, try the lab exercises at the end of the chapter. After you have done the lab exercises for a chapter, do the review questions located in the Prep Test at the end of the chapter.

These questions are designed to review the concepts presented in the chapter and give you an idea of the types of questions you may be asked on the exam.

I highly recommend not doing the practice tests on the CD until you have completed the entire book. I know a lot of people try the practice exams as they are reading through the book just to gauge their progress — as a result, they know all the practice test answers by the time they are done with the book.Also configure the enable secret for access to priv exec mode.
