Congratulations! If you’re reading far enough to look at this book’s Introduction, you’ve probably already decided to go for your Cisco certification, and the CCNA certification is the one place to begin that journey. If you want to succeed as a technical person in the networking industry at all, you need to know Cisco. Cisco has a ridiculously high market share in the router and switch marketplace, with more than 80 percent market share in some markets. In many geographies and markets around the world, networking equals Cisco. If you want to be taken seriously as a network engineer, Cisco certification makes perfect sense.
The first few pages of this Introduction explain the core features of the Cisco Career Certification program, of which the Cisco Certified Network Associate (CCNA) serves as the foundation for all the other certifications in the program. This section begins with a comparison of the old to the new certifications due to some huge program changes in 2019. It then gives the key features of CCNA, how to get it, and what’s on the exam.
Cisco announced sweeping changes to its career certification program around mid-year 2019. Because so many of you will have read and heard about the old versions of the CCNA certification, this Introduction begins with a few comparisons between the old and new CCNA as well as some of the other Cisco career certifications.
First, consider the Cisco career certifications before 2019, as shown in Figure I-1. At that time, Cisco offered 10 separate CCNA certifications in different technology tracks. Cisco also had eight Professional-level (CCNP, or Cisco Certified Network Professional) certifications.
Why so many? Cisco began with one track—Routing and Switching—back in 1998. Over time, Cisco identified more and more technology areas that had grown to have enough content to justify another set of CCNA and CCNP certifications on those topics, so Cisco added more tracks. Many of those also grew to support expert-level topics with CCIE (Cisco Certified Internetwork Expert).
In 2019, Cisco consolidated the tracks and moved the topics around quite a bit, as shown in Figure I-2.
All the tracks now begin with the content in the one remaining CCNA certification. For CCNP, you now have a choice of five technology areas for your next steps, as shown in Figure I-2. (Note that Cisco replaced “Routing and Switching” with “Enterprise.”)
Cisco made the following changes with the 2019 announcements:
CCENT: Retired the only entry-level certification (CCENT, or Cisco Certified Entry Network Technician), with no replacement.
CCNA: Retired all the CCNA certifications except what was then known as “CCNA Routing and Switching,” which became simply “CCNA.”
CCNP: Consolidated the professional-level (CCNP) certifications to five tracks, including merging CCNP Routing and Switching and CCNP Wireless into CCNP Enterprise.
CCIE: Achieved better alignment with CCNP tracks through the consolidations.
Cisco needed to move many of the individual exam topics from one exam to another because of the number of changes. For instance, Cisco announced the retirement of all the associate certifications—nine CCNA certifications plus the CCDA (Design Associate) certification—but those technologies didn’t disappear! Cisco just moved the topics around to different exams in different certifications. (Note that Cisco later announced that CCNA Cyber Ops would remain, and not be retired, with details to be announced.)
Consider wireless LANs as an example. The 2019 announcements retired both CCNA Wireless and CCNP Wireless as certifications. Some of the old CCNA Wireless topics landed in the new CCNA, whereas others landed in the two CCNP Enterprise exams about wireless LANs.
For those of you who want to learn more about the transition, check out my blog (https://blog.certskills.com) and look for posts in the News category from around June 2019. Now on to the details about CCNA as it exists starting in 2019!
As you saw in Figure I-2, all career certification paths now begin with CCNA. So how do you get it? Today, you have one and only one option to achieve CCNA certification:
Take and pass one exam: the Cisco 200-301 CCNA exam.
To take the 200-301 exam, or any Cisco exam, you will use the services of Pearson VUE (vue.com). The process works something like this:
Establish a login at https://home.pearsonvue.com/ (or use your existing login).
Register for, schedule a time and place, and pay for the Cisco 200-301 exam, all from the VUE website.
Take the exam at the VUE testing center.
You will receive a notice of your score, and whether you passed, before you leave the testing center.
The Cisco CCNA and CCNP exams all follow the same general format, with these types of questions:
Testlet (one scenario with multiple multiple-choice questions)
Simulated lab (sim)
Although the first four types of questions in the list should be somewhat familiar to you from other tests in school, the last two are more common to IT tests and Cisco exams in particular. Both use a network simulator to ask questions so that you control and use simulated Cisco devices. In particular:
Sim questions: You see a network topology and lab scenario, and can access the devices. Your job is to fix a problem with the configuration.
Simlet questions: This style combines sim and testlet question formats. As with a sim question, you see a network topology and lab scenario, and can access the devices. However, as with a testlet, you also see multiple multiple-choice questions. Instead of changing or fixing the configuration, you answer questions about the current state of the network.
These two question styles with the simulator give Cisco the ability to test your configuration skills with sim questions, and your verification and troubleshooting skills with simlet questions.
Before taking the test, learn the exam user interface by watching some videos Cisco provides about the interface. To find the videos, just go to www.cisco.com and search for “Cisco Certification Exam Tutorial Videos.”
Ever since I was in grade school, whenever a teacher announced that we were having a test soon, someone would always ask, “What’s on the test?” We all want to know, and we all want to study what matters and avoid studying what doesn’t matter.
Cisco tells the world the topics on each of its exams. Cisco wants the public to know the variety of topics and get an idea about the kinds of knowledge and skills required for each topic for every Cisco certification exam. To find the details, go to www.cisco.com/go/certifications, look for the CCNA page, and navigate until you see the exam topics.
This book also lists those same exam topics in several places. From one perspective, every chapter sets about to explain a small set of exam topics, so each chapter begins with the list of exam topics covered in that chapter. However, you might want to also see the exam topics in one place, so Appendix G, “Exam Topics Cross-Reference,” lists all the exam topics. You may want to download Appendix G in PDF form and keep it handy. The appendix lists the exam topics with two different cross-references:
A list of exam topics and the chapter(s) that covers each topic
A list of chapters and the exam topics covered in each chapter
Reading and understanding the exam topics, especially deciding the depth of skills required for each exam topic, require some thought. Each exam topic mentions the name of some technology, but it also lists a verb that implies the depth to which you must master the topic. The primary exam topics each list one or more verbs that describe the skill level required. For example, consider the following exam topic:
Configure and verify IPv4 addressing and subnetting
Note that this one exam topic has two verbs (configure and verify). Per this exam topic, you should be able to not only configure IPv4 addresses and subnets, but you also should understand them well enough to verify that the configuration works. In contrast, the following exam topic asks you to describe a technology but does not ask you to configure it:
Describe the purpose of first hop redundancy protocol
The describe verb tells you to be ready to describe whatever a “first hop redundancy protocol” is. That exam topic also implies that you do not then need to be ready to configure or verify any first hop redundancy protocols (HSRP, VRRP, and GLBP).
Finally, note that the configure and verify exam topics imply that you should be able to describe and explain and otherwise master the concepts so that you understand what you have configured. The earlier “Configure and verify IPv4 addressing and subnetting” does not mean that you should know how to type commands but have no clue as to what you configured. You must first master the conceptual exam topic verbs. The progression runs something like this:
Describe, Identify, Explain, Compare/Contrast, Configure, Verify, Troubleshoot
For instance, an exam topic that lists “compare and contrast” means that you should be able to describe, identify, and explain the technology. Also, an exam topic with “configure and verify” tells you to also be ready to describe, explain, and compare/contrast.
Take a moment to navigate to www.cisco.com/go/certifications and find the list of exam topics for the CCNA 200-301 exam. Did your eyes go straight to the list of exam topics? Or did you take the time to read the paragraphs above the exam topics first?
That list of exam topics for the CCNA 200-301 exam includes a little over 50 primary exam topics and about 50 more secondary exam topics. The primary topics have those verbs as just discussed, which tell you something about the depth of skill required. The secondary topics list only the names of more technologies to know.
However, the top of the web page that lists the exam topics also lists some important information that tells us some important facts about the exam topics. In particular, that leading text, found at the beginning of Cisco exam topic pages of most every exam, tells us these important points:
The guidelines may change over time.
The exam topics are general guidelines about what may be on the exam.
The actual exam may include “other related topics.”
Interpreting these three facts in order, I would not expect to see a change to the published list of exam topics for the exam. I’ve been writing the Cisco Press CCNA Cert Guides since Cisco announced CCNA back in 1998, and I’ve never seen Cisco change the official exam topics in the middle of an exam—not even to fix typos. But the introductory words say that they might change the exam topics, so it’s worth checking.
As for the second item in the preceding list, even before you know what the acronyms mean, you can see that the exam topics give you a general but not detailed idea about each topic. The exam topics do not attempt to clarify every nook and cranny or to list every command and parameter; however, this book serves as a great tool in that it acts as a much more detailed interpretation of the exam topics. We examine every exam topic, and if we think a concept or command is possibly within an exam topic, we put it into the book. So, the exam topics give us general guidance, and these books give us much more detailed guidance.
The third item in the list uses literal wording that runs something like this: “However, other related topics may also appear on any specific delivery of the exam.” That one statement can be a bit jarring to test takers, but what does it really mean? Unpacking the statement, it says that such questions may appear on any one exam but may not; in other words, they don’t set about to ask every test taker some questions that include concepts not mentioned in the exam topics. Second, the phrase “…other related topics…” emphasizes that any such questions would be related to some exam topic, rather than being far afield—a fact that helps us in how we respond to this particular program policy.
For instance, the CCNA 200-301 exam includes configuring and verifying the OSPF routing protocol, but it does not mention the EIGRP routing protocol. I personally would be unsurprised to see an OSPF question that required a term or fact not specifically mentioned in the exam topics, but not one that’s some feature that (in my opinion) ventures far away from the OSPF features in the exam topics. Also, I would not expect to see a question about how to configure and verify EIGRP.
And just as one final side point, note that Cisco does on occasion ask a test taker some unscored questions, and those may appear to be in this vein of questions from outside topics. When you sit down to take the exam, the small print mentions that you may see unscored questions and you won’t know which ones are unscored. (These questions give Cisco a way to test possible new questions.) Yet some of these might be ones that fall into the “other related topics” category but then not affect your score.
You should prepare a little differently for any Cisco exam, in comparison to, say, an exam back in school, in light of Cisco’s “other related questions” policy:
Do not approach an exam topic with an “I’ll learn the core concepts and ignore the edges” approach.
Instead, approach each exam topic with a “pick up all the points I can” approach by mastering each exam topic, both in breadth and in depth.
Go beyond each exam topic when practicing configuration and verification by taking a little extra time to look for additional show commands and configuration options, and make sure you understand as much of the show command output that you can.
By mastering the known topics, and looking for places to go a little deeper, you will hopefully pick up the most points you can from questions about the exam topics. Then the extra practice you do with commands may happen to help you learn beyond the exam topics in a way that can help you pick up other points as well.
When we created the Official Cert Guide content for the CCNA 200-301 exam, we considered a few options for how to package the content, and we landed on releasing a two-book set. Figure I-3 shows the setup of the content, with roughly 60 percent of the content in Volume 1 and the rest in Volume 2.
The two books together cover all the exam topics in the CCNA 200-301 exam. Each chapter in each book develops the concepts and commands related to an exam topic, with clear and detailed explanations, frequent figures, and many examples that build your understanding of how Cisco networks work.
As for choosing what content to put into the books, note that we begin and finish with Cisco’s exam topics, but with an eye toward predicting as many of the “other related topics” as we can. We start with the list of exam topics and apply a fair amount of experience, discussion, and other secret sauce to come up with an interpretation of what specific concepts and commands are worthy of being in the books or not. At the end of the writing process, the books should cover all the published exam topics, with additional depth and breadth that I choose based on the analysis of the exam. As we have done from the very first edition of the CCNA Official Cert Guide, we intend to cover each and every topic in depth. But as you would expect, we cannot predict every single fact on the exam given the nature of the exam policies, but we do our best to cover all known topics.
This book includes many study features beyond the core explanations and examples in each chapter. This section acts as a reference to the various features in the book.
Each chapter of this book is a self-contained short course about one small topic area, organized for reading and study, as follows:
“Do I Know This Already?” quizzes: Each chapter begins with a pre-chapter quiz.
Foundation Topics: This is the heading for the core content section of the chapter.
Chapter Review: This section includes a list of study tasks useful to help you remember concepts, connect ideas, and practice skills-based content in the chapter.
Figure I-4 shows how each chapter uses these three key elements. You start with the DIKTA quiz. You can use the score to determine whether you already know a lot, or not so much, and determine how to approach reading the Foundation Topics (that is, the technology content in the chapter). When finished, use the Chapter Review tasks to start working on mastering your memory of the facts and skills with configuration, verification, and troubleshooting.
In addition to these three main chapter features, each “Chapter Review” section uses a variety of other book features, including the following:
Review Key Topics: Inside the “Foundation Topics” section, the Key Topic icon appears next to the most important items, for the purpose of later review and mastery. While all content matters, some is, of course, more important to learn, or needs more review to master, so these items are noted as key topics. The Chapter Review lists the key topics in a table. Scan the chapter for these items to review them. Or review the key topics interactively using the companion website.
Complete Tables from Memory: Instead of just rereading an important table of information, you will find some tables have been turned into memory tables, an interactive exercise found on the companion website. Memory tables repeat the table but with parts of the table removed. You can then fill in the table to exercise your memory and click to check your work.
Key Terms You Should Know: You do not need to be able to write a formal definition of all terms from scratch; however, you do need to understand each term well enough to understand exam questions and answers. The Chapter Review lists the key terminology from the chapter. Make sure you have a good understanding of each term and use the Glossary to cross-check your own mental definitions. You can also review key terms with the “Key Terms Flashcards” app on the companion website.
Labs: Many exam topics use verbs such as configure and verify; all these refer to skills you should practice at the user interface (CLI) of a router or switch. The Chapter and Part Reviews refer you to these other tools. The upcoming section titled “About Building Hands-On Skills” discusses your options.
Command References: Some book chapters cover a large number of router and switch commands. The Chapter Review includes reference tables for the commands used in that chapter, along with an explanation. Use these tables for reference, but also use them for study. Just cover one column of the table and see how much you can remember and complete mentally.
Review DIKTA Questions: Although you have already seen the DIKTA questions from the chapters, re-answering those questions can prove a useful way to review facts. The Part Review suggests that you repeat the DIKTA questions but using the Pearson Test Prep (PTP) exam.
The book organizes the chapters into parts for the purpose of helping you study for the exam. Each part groups a small number of related chapters together. Then the study process (described just before Chapter 1) suggests that you pause after each part to do a review of all chapters in the part. Figure I-5 lists the titles of the eight parts and the chapters in those parts (by chapter number) for this book.
The Part Review that ends each part acts as a tool to help you with spaced review sessions. Spaced reviews—that is, reviewing content several times over the course of your study—help improve retention. The Part Review activities include many of the same kinds of activities seen in the Chapter Review. Avoid skipping the Part Review, and take the time to do the review; it will help you in the long run.
We created an electronic version of every Chapter and Part Review task that could be improved though an interactive version of the tool. For instance, you can take a “Do I Know This Already?” quiz by reading the pages of the book, but you can also use our testing software. As another example, when you want to review the key topics from a chapter, you can find all those in electronic form as well.
All the electronic review elements, as well as other electronic components of the book, exist on this book’s companion website. The companion website gives you a big advantage: you can do most of your Chapter and Part Review work from anywhere using the interactive tools on the site. The advantages include
Easier to use: Instead of having to print out copies of the appendixes and do the work on paper, you can use these new apps, which provide you with an easy-to-use, interactive experience that you can easily run over and over.
Convenient: When you have a spare 5–10 minutes, go to the book’s website and review content from one of your recently finished chapters.
Untethered from the book: You can access your review activities from anywhere— no need to have the book with you.
Good for tactile learners: Sometimes looking at a static page after reading a chapter lets your mind wander. Tactile learners might do better by at least typing answers into an app, or clicking inside an app to navigate, to help keep you focused on the activity.
The interactive Chapter Review elements should improve your chances of passing as well. Our in-depth reader surveys over the years show that those who do the Chapter and Part Reviews learn more. Those who use the interactive versions of the review elements also tend to do more of the Chapter and Part Review work. So take advantage of the tools and maybe you will be more successful as well. Table I-1 summarizes these interactive applications and the traditional book features that cover the same content.

CCNA 200-301 Network Simulator Lite: This lite version of the best-selling CCNA Network Simulator from Pearson provides you with a means, right now, to experience the Cisco command-line interface (CLI). No need to go buy real gear or buy a full simulator to start learning the CLI. Just install it from the companion website.
CCNA Simulator: If you are looking for more hands-on practice, you might want to consider purchasing the CCNA Network Simulator. You can purchase a copy of this software from Pearson at http://pearsonitcertification.com/networksimulator or other retail outlets. To help you with your studies, Pearson has created a mapping guide that maps each of the labs in the simulator to the specific sections in each volume of the CCNA Cert Guide. You can get this mapping guide free on the Extras tab on the book product page: www.ciscopress.com/title/9781587147135.
PearsonITCertification.com: The website www.pearsonitcertification.com is a great resource for all things IT-certification related. Check out the great CCNA articles, videos, blogs, and other certification preparation tools from the industry’s best authors and trainers.
Author’s website and blogs: The author maintains a website that hosts tools and links useful when studying for CCNA. In particular, the site has a large number of free lab exercises about CCNA content, additional sample questions, and other exercises. Additionally, the site indexes all content so you can study based on the book chapters and parts. To find it, navigate to https://blog.certskills.com.
The CCNA 200-301 Official Cert Guide, Volume 1, contains 29 chapters, while this book has 19 core chapters. Each chapter covers a subset of the topics on the CCNA exam. The book organizes its chapters into parts of three to five chapters as follows:
Chapter 1, “Introduction to TCP/IP Transport and Applications,” completes most of the detailed discussion of the upper two layers of the TCP/IP model (transport and application), focusing on TCP and applications.
Chapter 6, “Implementing Switch Port Security,” explains the concepts as well as how to configure and verify switch port security, a switch feature that does basic MAC-based monitoring of the devices that send data into a switch.
Chapter 8, “DHCP Snooping and ARP Inspection,” shows how to implement two related switch security features, with one focusing on reacting to suspicious DHCP messages and the other reacting to suspicious ARP messages.
Chapter 10, “Network Address Translation,” works through the complete concept, configuration, verification, and troubleshooting sequence for the router NAT feature, including how it helps conserve public IPv4 addresses.
Chapter 12, “Miscellaneous IP Services,” discusses several topics for which the exam requires conceptual knowledge but no configuration knowledge, including FHRPs (including HSRP), SNMP, TFTP, and FTP.
Chapter 15, “Cloud Architecture,” explains the basic concepts and then generally discusses the impact that cloud computing has on a typical enterprise network, including the foundational concepts of server virtualization.
Chapter 16, “Introduction to Controller-Based Networking,” discusses many concepts and terms related to how Software-Defined Networking (SDN) and network programmability are impacting typical enterprise networks.
Appendix B, “CCNA 200-301 Volume 2 Exam Updates,” is a place for the author to add book content mid-edition. Always check online for the latest PDF version of this appendix; the appendix lists download instructions.
The Glossary contains definitions for many of the terms used in the book, including the terms listed in the “Key Terms You Should Know” sections at the conclusion of the chapters.
You need skills in using Cisco routers and switches, specifically the Cisco command-line interface (CLI). The Cisco CLI is a text-based command-and-response user interface: you type a command, and the device (a router or switch) displays messages in response. To answer sim and simlet questions on the exams, you need to know a lot of commands, and you need to be able to navigate to the right place in the CLI to use those commands.
This next section walks through the options of what is included in the book, with a brief description of lab options outside the book.
Some router and switch features require multiple configuration commands. Part of the skill you need to learn is to remember which configuration commands work together, which ones are required, and which ones are optional. So, the challenge level goes beyond just picking the right parameters on one command. You have to choose which commands to use, in which combination, typically on multiple devices. And getting good at that kind of task requires practice.
Each Config Lab lists details about a straightforward lab exercise for which you should create a small set of configuration commands for a few devices. Each lab presents a sample lab topology, with some requirements, and you have to decide what to configure on each device. The answer then shows a sample configuration. Your job is to create the configuration and then check your answer versus the supplied answer.
Config Lab content resides outside the book at the author’s blog site (https://blog.certskills.com). You can navigate to the Config Lab in a couple of ways from the site, or just go directly to https://blog.certskills.com/category/hands-on/config-lab/ to reach a list of all Config Labs. Figure I-6 shows the logo that you will see with each Config Lab.
These Config Labs have several benefits, including the following:
Untethered and responsive: Do them from anywhere, from any web browser, from your phone or tablet, untethered from the book.
Designed for idle moments: Each lab is designed as a 5- to 10-minute exercise if all you are doing is typing in a text editor or writing your answer on paper.
Two outcomes, both good: Practice getting better and faster with basic configuration, or if you get lost, you have discovered a topic that you can now go back and reread to complete your knowledge. Either way, you are a step closer to being ready for the exam!
Blog format: The format allows easy adds and changes by me and easy comments by you.
Self-assessment: As part of final review, you should be able to do all the Config Labs, without help, and with confidence.
Note that the blog organizes these Config Lab posts by book chapter, so you can easily use these at both Chapter Review and Part Review.
The decision of how to get hands-on skills can be a little scary at first. The good news: You have a free and simple first step to experience the CLI: install and use the Pearson Network Simulator Lite (or NetSim Lite) that comes with this book.
This book comes with a lite version of the best-selling CCNA Network Simulator from Pearson, which provides you with a means, right now, to experience the Cisco CLI. No need to go buy real gear or buy a full simulator to start learning the CLI. Just install it from the companion website.
The CCNA 200-301 Network Simulator Lite Volume 2 software contains 13 labs covering ACL topics from Part I in the book. So, make sure to use the NetSim Lite to learn the basics of the CLI to get a good start.
Of course, one reason that you get access to the NetSim Lite is that the publisher hopes you will buy the full product. However, even if you do not use the full product, you can still learn from the labs that come with NetSim Lite while deciding about what options to pursue.
The Config Labs and the Pearson Network Simulator Lite both fill specific needs, and they both come with the book. However, you need more than those two tools.
The single best option for lab work to do along with this book is the paid version of the Pearson Network Simulator. This simulator product simulates Cisco routers and switches so that you can learn for CCNA certification. But more importantly, it focuses on learning for the exam by providing a large number of useful lab exercises. Reader surveys tell us that those people who use the Simulator along with the book love the learning process and rave about how the book and Simulator work well together.
Of course, you need to make a decision for yourself and consider all the options. Thankfully, you can get a great idea of how the full Simulator product works by using the Pearson Network Simulator Lite product included with the book. Both have the same base code, same user interface, and same types of labs. Try the Lite version to decide if you want to buy the full product.
Note that the Simulator and the books work on a different release schedule. For a time in 2020, the Simulator will be the one created for the previous versions of the exams (ICND1 100-101, ICND2 200-101, and CCNA 200-120). Interestingly, Cisco did not add a large number of new topics that require CLI skills to the CCNA 200-301 exam as compared with its predecessor, so the old Simulator covers most of the CCNA 200-301 CLI topics. So, during the interim before the products based on the 200-301 exam come out, the old Simulator products should be quite useful.
On a practical note, when you want to do labs when reading a chapter or doing Part Review, the Simulator organizes the labs to match the book. Just look for the Sort by Chapter tab in the Simulator’s user interface. However, during the months in 2020 for which the Simulator is the older edition listing the older exams in the title, you will need to refer to a PDF that lists those labs versus this book’s organization. You can find that PDF on the book product page under the Downloads tab here: www.ciscopress.com/title/9781587147135.
If you decide against using the full Pearson Network Simulator, you still need hands-on experience. You should plan to use some lab environment to practice as much CLI as possible.
First, you can use real Cisco routers and switches. You can buy them, new or used, or borrow them at work. You can rent them for a fee. If you have the right mix of gear, you could even do the Config Lab exercises from my blog on that gear or try to recreate examples from the book.
Cisco also makes a simulator that works very well as a learning tool: Cisco Packet Tracer. Cisco now makes Packet Tracer available for free. However, unlike the Pearson Network Simulator, it does not include lab exercises that direct you as to how to go about learning each topic.

Cisco offers a virtualization product that lets you run router and switch operating system (OS) images in a virtual environment. This tool, the Virtual Internet Routing Lab (VIRL), lets you create a lab topology, start the topology, and connect to real router and switch OS images. Check out http://virl.cisco.com for more information.
You can even rent virtual Cisco router and switch lab pods from Cisco, in an offering called Cisco Learning Labs (https://learningnetworkstore.cisco.com/cisco-learning-labs).
This book does not tell you what option to use, but you should plan on getting some hands-on practice somehow. The important thing to know is that most people need to practice using the Cisco CLI to be ready to pass these exams.
