iv31 Days Before Your CCENT Certification ExamAbout the AuthorAllan Johnson entered the academic world in 1999 after ten years as a business owner/operator to dedicate his efforts to his passion for teaching. He holds both an MBA andan M.Ed. in occupational training and development. He taught CCNA courses at thehigh school level for seven years and has taught both CCNA and CCNP courses at DelMar College in Corpus Christi, Texas. In 2003, Allan began to commit much of his timeand energy to the CCNA Instructional Support Team, providing services to NetworkingAcademy instructors worldwide and creating training materials. He now works full time forCisco Networking Academy as a learning systems developer.About the Technical ReviewerSteve Stiles is a Cisco Networking Academy Instructor for Rhodes State College and aCisco Certified Instructor Trainer, having earned CCNA Security and CCNP level certifications. He was the recipient of the 2012 Outstanding Teacher of the Year award by the OhioAssociation of Two Year Colleges and co-recipient of the Outstanding Faculty of the Yearaward at Rhodes State College.
vDedicationFor my wife, Becky. Without the sacrifices you made during the project, this work wouldnot have come to fruition. Thank you for providing me the comfort and resting place onlyyou can give.
vi31 Days Before Your CCENT Certification ExamAcknowledgmentsWhen I began to think of whom I would like to have as a technical editor for this work,Steve Stiles immediately came to mind. With his instructor and industry background, aswell as his excellent work building activities for the new Cisco Networking Academy curriculum, he was an obvious choice. Thankfully, when Mary Beth Ray contacted him, he waswilling and able to do the arduous review work necessary to make sure that you get a bookthat is both technically accurate and unambiguous.This book is a concise summary of the work of Cisco Press CCNA authors. WendellOdom’s Cisco CCENT/CCNA ICND1 100-101 Official Cert Guide and AnthonySequeira’s Interconnecting Cisco Network Devices, Part 1 (ICND1) Foundation LearningGuide were two of my main sources. The different approaches that these two authors—both CCIEs—take toward the CCNA material gives the reader the breadth and the depthneeded to master the CCNA exam topics.The Cisco Networking Academy authors for the online curriculum and series ofCompanion Guides take the reader deeper, past the CCNA exam topics, with the ultimategoal of not only preparing the student for CCNA certification, but also for more advancedcollege-level technology courses and degrees. Thank you especially to Amy Gerrie and herteam of authors—Rick Graziani, Wayne Lewis, and Bob Vachon—for their excellent treatment of the material; it is reflected throughout this book.Mary Beth Ray, executive editor, amazes me with her ability to juggle multiple projects atonce, steering each from beginning to end. I can always count on her to make the toughdecisions. Thank you, Mary Beth, for bringing this project to me.This is my fifth project with Christopher Cleveland as development editor. His dedication toperfection pays dividends in countless, unseen ways. Thank you again, Chris, for providingme with much needed guidance and support. This book could not be a reality without yourpersistence.

xxiiiIntroductionYou are almost there! If you’re reading this Introduction, you’ve probably already spent aconsiderable amount of time and energy pursuing your CCENT certification. Regardlessof how you got to this point in your travels through your CCENT studies, 31 Days BeforeYour CCENT Certification Exam most likely represents the last leg of your journey onyour way to the destination: to become a Cisco Certified Entry Networking Technician.However, if you are like I am, you might be reading this book at the beginning of yourstudies. If such is the case, this book provides you with an excellent overview of the material that you must now spend a great deal of time studying and practicing. However, I mustwarn you: Unless you are extremely well-versed in networking technologies and have considerable experience configuring and troubleshooting Cisco routers and switches, this bookwill not serve you well as the sole resource for CCENT exam preparation. Therefore, let mespend some time discussing my recommendations for study resources.Study ResourcesCisco Press offers an abundance of CCNA-related books to serve as your primary sourcefor learning how to install, configure, operate, and troubleshoot small- to medium-sizerouted and switched networks.Primary ResourcesFirst on the list must be Wendell Odom’s Cisco CCENT/CCNA ICND1 100-101 OfficialCert Guide (ISBN: 9781587143854). If you do not buy any other books, buy this one.Wendell’s method of teaching, combined with his technical expertise and down-to-earthstyle, is unsurpassed in our industry. As you read through his books, you sense that he issitting right there next to you walking you through the material. The practice exams andstudy materials on the DVD in the back of the book are worth the price of the book. Thereis no better resource on the market for a CCNA candidate.Next on the list must be Anthony Sequeira’s Interconnecting Cisco Network Devices,Part 1 (ICND1) Foundation Learning Guide (ISBN: 9781587143762). This book is indispensable to those students who take the first of two Cisco-recommended training classfor CCNA preparation: Interconnecting Cisco Network Devices 1 (ICND1). These courses,available through Cisco Training Partners in a variety of formats, are usually of a veryshort duration (one to six weeks) and are geared toward the industry professional alreadyworking in the field of networking. Anthony’s book serves the reader well as a concise, butthorough, treatment of the CCENT exam topics. His method and approach often differ andcomplement Wendell’s approach. I recommend that you also refer to this book.If you are a Cisco Networking Academy student, you are blessed with access to the onlineversion of the CCNA Routing and Switching curriculum and the wildly popular PacketTracer network simulator. Although there are currently two paths for the CCNA curriculum,I used the Introduction to Networking (ITN) and Routing and Switching Essential (RSE)courses in my daily review of the exam topics. ITN introduces basic concepts of computernetworks, including deep dives into the seven layers of the OSI model, IP addressing, andthe fundamentals of Ethernet. Successfully completing the course means that you shouldbe able to build small LANs and implement basic addressing and configurations on routers
xxiv31 Days Before Your CCENT Certification Examand switches. RSE expands on ITN, taking the student further into basic router and switchconfiguration. Successfully completing the course means that you should be able to configure and troubleshoot routers and switches using a variety of technologies including RIPv2,single-area OSPF, VLANs, and inter-VLAN routing for both IPv4 and IPv6 networks. Tolearn more about CCNA Routing and Switching courses and to find an Academy near you,visit www.netacad.com.However, if you are not an Academy student but would like to benefit from the extensiveauthoring done for these courses, you can buy any or all the CCNA Routing and SwitchingCompanion Guides (CG) and Lab Manuals (LM) of the Academy’s popular online curriculum. Although you will not have access to the Packet Tracer network simulator software, you will have access to the tireless work of an outstanding team of Cisco AcademyInstructors dedicated to providing students with comprehensive and engaging CCNA preparation course material. The titles and ISBNs for the CCNA Routing and Switching CGs andLMs are as follows:QIntroduction to Networks Companion Guide (ISBN: 9781587133169)QIntroduction to Networks Lab Manual (ISBN: 9781587133121)QRouting and Switching Essentials Companion Guide (ISBN: 9781587133183)QRouting and Switching Essentials Lab Manual (ISBN: 9781587133206)You can find these books at www.ciscopress.com by clicking the Cisco NetworkingAcademy link.Supplemental ResourcesIn addition to the book you hold in your hands, there are four more supplemental resourcesI recommend to augment your final 31 days of review and preparation.First, a plug for my own book, the CCENT Practice and Study Guide, Exercises,Activities and Scenarios to Prepare for the ICND1/CCENT (100-101) CertificationExam (ISBN: 9781587133459). The subtitle is a concise summary of what you will get.Although an appropriate resource for anyone, this book is specifically geared toward theCisco Networking Academy instructors and students who want a resource to supplementthe online curriculum. Mirroring the chapter layout of the first two online courses, theCCENT PSG offers exercises that help you learn the concepts and configurations that arecrucial to your success as a CCENT candidate.Second, Wendell Odom and Sean Wilkins have created over 250 structured labs that areavailable in the Cisco CCENT ICND1 100-101 Network Simulator (ISBN: 9780789750433).These simulations map precisely to chapters in his book, but are also a great practiceresource for anyone. The four types of labs in this product present you with progressivelymore difficult real-world challenges. Skill builder labs help you practice short, focusedconfiguration tasks. Subnetting exercises help you improve the speed and accuracy of yoursubnetting calculations. Complex Configuration Scenario labs present realistic multilayered,multitechnology configuration tasks. Finally, challenging Troubleshooting Scenario labsprovide you with an opportunity to test your problem identification and resolution skills. Ifyou need that extra edge or are struggling with a particular configuration or troubleshooting concept, you’ll find these simulations very helpful.
xxvThird, Eric Rivard is the author of Cisco CCENT ICND1 100-101 Flash Cards and ExamPractice Pack (ISBN: 9781587203992). The text portion of the book includes over 450flash cards that quickly review exam topics in bite-sized pieces. Also included is over 100pages in the Quick Reference Guide, which is designed for late-stage exam preparation. Andon the included CD, you will find a test engine with over 150 CCENT practice exam questions.NOTE: If you are certain that you will be also pursuing your CCNA certification, the moreeconomical purchase might be to buy the Cisco CCNA Routing and Switching 200-120Flash Cards and Exam Practice Pack (ISBN: 9781587204005). The first half of this book isa repeat of the CCENT version.Fourth, there is Scott Empson’s very popular CCNA Routing and Switching PortableCommand Guide, Third Edition (ISBN: 9781587204302). This guide is way more than justa listing of commands and what they do. Yes, it summarizes all the CCNA certification-levelIOS commands, keywords, command arguments, and associated prompts. But it also provides you with tips and examples of how to apply the commands to real-world scenarios.Configuration examples throughout the book provide you with a better understanding ofhow these commands are used in simple network designs.The Cisco Learning NetworkFinally, if you have not done so already, you should now register with The Cisco LearningNetwork at https://learningnetwork.cisco.com. Sponsored by Cisco, The Cisco LearningNetwork is a free social learning network where IT professionals can engage in the commonpursuit of enhancing and advancing their IT careers. Here you will find many resources tohelp you prepare for your CCNA exam as well as a community of like-minded people readyto answer your questions, help you with your struggles, and share in your triumphs.So which resources should you buy? That question is largely up to how deep your pocketsare or how much you like books. If you’re like I am, you must have it all! I admit it. Mybookcase is a testament to my Cisco “geekness.” But if you are on a budget, choose oneof the primary study resources and one of the supplemental resources, such as WendellOdom’s certification book and my practice study guide. Whatever you choose, you will bein good hands. Any or all of these authors will serve you well.Goals and MethodsThe main goal of this book is to provide you with a clear and succinct review of theCCENT objectives. Each day’s exam topics are grouped into a common conceptual framework and use the following format:QA title for the day that concisely states the overall topicQA list of one or more CCENT 100-101 ICND1 Exam Topics to be reviewedQA Key Topics section to introduce the review material and quickly orient you to theday’s focusQAn extensive review section consisting of short paragraphs, lists, tables, examples, andgraphics
