Why Become a CCENT and CCNA R/S?
Cisco, like Microsoft and other vendors that provide certification, has
created the certification process to give administrators a set of skills and
to equip prospective employers with a way to measure those skills or
match certain criteria. And as you probably know, becoming a CCNA R/S
is certainly the initial, key step on a successful journey toward a new,
highly rewarding, and sustainable networking career.
The CCNA program was created to provide a solid introduction not only
to the Cisco Internetwork Operating System (IOS) and Cisco hardware
but also to internetworking in general, making it helpful to you in areas
that are not exclusively Cisco's. And regarding today's certification
process, it's not unrealistic that network managers—even those without
Cisco equipment—require Cisco certifications for their job applicants.
Rest assured that if you make it through the CCNA and are still interested
in Cisco and internetworking, you're headed down a path to certain
success!
What Skills Do You Need to Become a CCNA
R/S?
This ICND1 exam (100-105) tests a candidate for the knowledge and skills
required to successfully install, operate, and troubleshoot a small branch
office network. The exam includes questions on the operation of IP data
networks, LAN switching technologies, IPv6, IP routing technologies, IP
services, network device security, and basic troubleshooting. The ICND2
exam (exam 200-105) tests a candidate for the knowledge and skills
required to successfully install, operate, and troubleshoot a small- to
medium-size enterprise branch network. The exam includes questions on
LAN switching technologies, IP routing technologies, security,
troubleshooting, and WAN technologies.
How Do You Become a CCNA R/S
If you want to go straight for our CCNA R/S and take only one exam, all
you have to do is pass the CCNA Composite exam (200-125). Oh, but
don't you wish it were that easy? True, it's just one test, but it's a
whopper, and to pass it you must possess enough knowledge to
understand what the test writers are saying, and you need to know
everything I mentioned previously, in the sections on the ICND1 and
ICND2 exams! Hey, it's hard, but it can be done!
What does the CCNA Composite exam (200-125) cover? Pretty much the
same topics covered in the ICND1 and ICND2 exams. Candidates can
prepare for this exam by taking the Todd Lammle authorized Cisco boot
camps. 200-125 tests a candidate's knowledge and skills required to
install, operate, and troubleshoot a small- to medium-size enterprise
branch network.
While you can take the Composite exam to get your CCNA, it's good to
know that Cisco offers the two-step process I discussed earlier in this
Introduction. And this book covers both those exams too! It may be easier
than taking that one ginormous exam for you, but don't think the two-test
method is easy. It takes work! However, it can be done; you just need to
stick with your studies.
The two-test method involves passing the following:
Exam 100-105: Interconnecting Cisco Networking Devices Part 1
(ICND1)
Exam 200-105: Interconnecting Cisco Networking Devices Part 2
(ICND2)
I can't stress this point enough: It's critical that you have some hands-on
experience with Cisco routers. If you can get a hold of some basic routers
and switches, you're set, but if you can't, I've worked hard to provide
hundreds of configuration examples throughout this book to help
network administrators, or people who want to become network
administrators, learn the skills they need to pass the CCENT and CCNA
R/S exams.
For Cisco certification hands-on training with CCSI Todd
Lammle, please see:
www.lammle.com/ccna
. Each student will get
hands-on experience by configuring at least three routers and two
switches.no sharing of equipment!
What Does This Book Cover?
This book covers everything you need to know to pass the ICND1 (100-
105) and ICND2 (200-105) exams, as well as the CCNA Composite (200-
125) exam. But regardless of which path you choose, as I've said, taking
plenty of time to study and practice with routers or a router simulator is
the real key to success.
You will learn the following information in this book:
Chapter 1: Internetworking Chapters 1.14 map to the ICND1 exam.
In Chapter 1, you will learn the basics of the Open Systems
Interconnection (OSI) model the way Cisco wants you to learn it. There
are written labs and plenty of review questions to help you. Do not even
think of skipping the fundamental written labs in this chapter!
Chapter 2: Ethernet Networking and Data Encapsulation This
chapter will provide you with the Ethernet foundation you need in order
to pass both the CCENT and CCNA exams. Data encapsulation is
discussed in detail in this chapter as well. And as with the other chapters,
this chapter includes written labs and review questions to help you.
Chapter 3: Introduction to TCP/IP This chapter provides you with
the background necessary for success on the exam, as well as in the real
world with a thorough presentation of TCP/IP. This in-depth chapter
covers the very beginnings of the Internet Protocol stack and goes all the
way to IP addressing and understanding the difference between a
network address and a broadcast address before finally ending with
network troubleshooting.
Chapter 4: Easy Subnetting You'll actually be able to subnet a
network in your head after reading this chapter if you really want to! And
you'll find plenty of help in this chapter as long as you don't skip the
written labs and review questions at the end.
Chapter 5: VLSMs, Summarization, and Troubleshooting
TCP/IP Here, you'll find out all about variable length subnet masks
(VLSMs) and how to design a network using VLSMs. This chapter will
finish with summarization techniques and configurations. As with
Chapter 4, plenty of help is there for you if you don't skip the written lab
and review questions.
Chapter 6: Cisco's Internetworking Operating System (IOS)
This chapter introduces you to the Cisco Internetworking Operating
System (IOS) and command-line interface (CLI). In this chapter you'll
learn how to turn on a router and configure the basics of the IOS,
including setting passwords, banners, and more. Hands-on labs will help
you gain a firm grasp of the concepts taught in the chapter. Before you go
through the hands-on labs, be sure to complete the written lab and review
questions.
Chapter 7: Managing a Cisco Internetwork This chapter provides
you with the management skills needed to run a Cisco IOS network.
Backing up and restoring the IOS, as well as router configuration, are
covered, as are the troubleshooting tools necessary to keep a network up
and running. As always, before tackling the hands-on labs in this chapter,
complete the written labs and review questions.
Chapter 8: Managing Cisco Devices This chapter describes the boot
process of Cisco routers, the configuration register, and how to manage
Cisco IOS files. The chapter finishes with a section on Cisco's new
licensing strategy for IOS. Hands-on and written labs, along with review
questions, will help you build a strong foundation for the objectives
covered in this chapter.
Chapter 9: IP Routing This is a fun chapter because we will begin to
build our network, add IP addresses, and route data between routers. You
will also learn about static, default, and dynamic routing using RIP and
RIPv2. Hands-on labs, a written lab, and the review questions will help
you fully nail down IP routing.
Chapter 10: Layer 2 Switching This chapter sets you up with the solid
background you need on layer 2 switching, how switches perform address
learning and make forwarding and filtering decisions. In addition, switch
port security with MAC addresses is covered in detail. As always, go
through the hands-on labs, written lab, and review questions to make
sure you've really got layer 2 switching down!
Chapter 11: VLANs and Inter-VLAN Routing Here I cover virtual
VLANs and how to use them in your internetwork. This chapter covers
the nitty-gritty of VLANs and the different concepts and protocols used
with VLANs. I'll also guide you through troubleshooting techniques in
this all-important chapter. The hands-on labs, written lab, and review
questions are there to reinforce the VLAN material.
Chapter 12: Security This chapter covers security and access lists,
which are created on routers to filter the network. IP standard, extended,
and named access lists are covered in detail. Written and hands-on labs,
along with review questions, will help you study for the security and
access-list portion of the Cisco exams.
Chapter 13: Network Address Translation (NAT) New
information, commands, troubleshooting, and detailed hands-on labs will
help you nail the NAT CCENT objectives.
Chapter 14: Internet Protocol Version 6 (IPv6) This is a fun
chapter chock-full of some great information. IPv6 is not the big, bad
scary creature that most people think it is, and it's a really important
objective on the latest exam, so study this chapter carefully—don't just
skim it. And make sure you hit those hands-on labs hard!
Chapter 15: Enhanced Switched Technologies Chapter 15 is the
first chapter of Part 2 of this book, which maps to the ICND2 exam. This
chapter will start off with STP protocols and dive into the fundamentals,
covering the modes, as well as the various flavors of STP. VLANs, trunks,
and troubleshooting are covered as well. EtherChannel technologies,
configuration, and verification are also covered. There are hands-on labs,
a written lab, and plenty of review questions to help you. Do not even
think of skipping the fundamental written and hands-on labs in this
chapter!
Chapter 16: Network Device Management and Security
Managing Cisco Devices This chapter describes the boot process of
Cisco routers, the configuration register, and how to manage Cisco IOS
files. The chapter finishes with a section on Cisco's new licensing strategy
for its IOS. Hands-on and written labs, along with review questions, will
help you build a strong foundation for the objectives covered in this
chapterhow to mitigate threats at the access layer using various security
techniques. AAA with RADIUIS and TACACS+, SNMP and HSRP are also
covered in this chapter. Don't skip the hands-on labs that are included, as
well as a written lab and review questions at the end of the chapter.
Chapter 17: Enhanced IGRP EIGRP was not covered in the ICND1
(CCENT) chapters, so this is a full chapter on nothing but EIGRP and
EIGRPv6. There are lots of examples, including configuration,
verification, and troubleshooting labs, with both IP and with IPv6. Great
hands-on labs are included, as well as a written lab and review questions.
Chapter 18: Open Shortest Path First (OSPF) Chapter 9 dives into
more complex dynamic routing by covering OSPF routing. The written
lab, hands-on labs, and review questions will help you master this vital
routing protocol.
Chapter 19: Multi-Area OSPF The ICND1 (CCENT) portion of this
book had a large chapter on OSPF, so before reading this chapter, be sure
you have the CCENT objectives down pat with a strong OSPF foundation.
This chapter will take off where that ICND1 chapter left off and add
multi-area networks along with advanced configurations and then finish
with OSPv3. Hands-on labs, a written lab, and challenging review
questions await you at the end of the chapter.
Chapter 20: Troubleshooting IP, IPv6, and VLANs I want to say
this is the most important chapter in the book, but that's hard to say. You
can decide that yourself when you take the exam! Be sure to go through
all the troubleshooting steps for IP, IPv6, and VLANs. The hands-on labs
for this chapter will be included in the free bonus material and dynamic
labs that I'll write and change as needed. Don't skip the written lab and
review questions.
Chapter 21: Wide Area Networks This is the longest, and last,
chapter in the book. It covers multiple protocols in depth, especially
HDLC, PPP, and Frame Relay, along with a discussion on many other
technologies. Good troubleshooting examples are provided in the PPP
and Frame Relay configuration sections, and these cannot be skipped!
Hands-on labs meant to focus squarely on the objectives are included at
the end of the chapter, as well as a written lab and challenging review
questions.
Chapter 22: Evolution of Intelligent Networks I saved the hardest
chapter for last. What makes this chapter challenging is that there is no
configuration section to you really need to dive deep into the cloud, APIC-
EM and QoS sections with an open and ready mind. I stuck as close to the
objectives as possible in order to help you ace the exam. The written lab
and review questions are spot on for the objectives.
Appendix A: Answers to Written Labs This appendix contains the
answers to the book's written labs.
Appendix B: Answers to Chapter Review Questions This
appendix provides the answers to the end-of-chapter review questions.
Appendix C: Disabling and Configuring Network Services
Appendix C takes a look at the basic services you should disable on your
routers to make your network less of a target for denial of service (DoS)
attacks and break-in attempts.

How to Use This Book
If you want a solid foundation for the serious effort of preparing for the
Interconnecting Cisco Network Devices Part 1 and 2 exams, or the CCNA
R/S Composite exam, then look no further. I've spent hundreds of hours
putting together this book with the sole intention of helping you to pass
the Cisco exams, as well as really learn how to correctly configure Cisco
routers and switches!
This book is loaded with valuable information, and you will get the most
out of your study time if you understand why the book is organized the
way it is.
So to maximize your benefit from this book, I recommend the following
study method:
1. Take the assessment test that's provided at the end of this
introduction. (The answers are at the end of the test.) It's okay if you
don't know any of the answers; that's why you bought this book!
Carefully read over the explanations for any questions you get wrong
and note the chapters in which the material relevant to them is
covered. This information should help you plan your study strategy.
2. Study each chapter carefully, making sure you fully understand the
information and the test objectives listed at the beginning of each one.
Pay extra-close attention to any chapter that includes material
covered in questions you missed.
3. Complete the written labs at the end of each chapter. (Answers to
these appear in Appendix A.) Do not skip these written exercises
because they directly relate to the Cisco exams and what you must
glean from the chapters in which they appear. Do not just skim these
labs! Make sure you completely understand the reason for each
correct answer.
4. Complete all hands-on labs in each chapter, referring to the text of the
chapter so that you understand the reason for each step you take. Try
to get your hands on some real equipment, but if you don't have Cisco
equipment available, try the LammleSim IOS version, which you can
use for the hands-on labs found only in this book. These labs will
equip you with everything you need for all your Cisco certification
goals.
5. Answer all of the review questions related to each chapter. (The
answers appear in Appendix B.) Note the questions that confuse you,
and study the topics they cover again until the concepts are crystal
clear. And again—do not just skim these questions! Make sure you
fully comprehend the reason for each correct answer. Remember that
these will not be the exact questions you will find on the exam, but
they're written to help you understand the chapter material and
ultimately pass the exam!
6. Try your hand at the practice questions that are exclusive to this book.
The questions can be found only at
www.wiley.com/go/sybextestprep
.
And be sure to check out
www.lammle.com/ccna
for the most up-to-
date Cisco exam prep questions, videos, Todd Lammle boot camps,
and more.
7. Test yourself using all the flashcards, which are also found on the
download link. These are brand-new and updated flashcards to help
you prepare for the CCNA R/S exam and a wonderful study tool!
To learn every bit of the material covered in this book, you'll have to
apply yourself regularly, and with discipline. Try to set aside the same
time period every day to study, and select a comfortable and quiet place
to do so. I'm confident that if you work hard, you'll be surprised at how
quickly you learn this material!
If you follow these steps and really study—doing hands-on labs every
single day in addition to using the review questions, the practice exams,
the Todd Lammle video sections, and the electronic flashcards, as well as
all the written labs—it would actually be hard to fail the Cisco exams. But
understand that studying for the Cisco exams is a lot like getting in shape
—if you do not go to the gym every day, it's not going to happen!
Where Do You Take the Exams?
You may take the ICND1, ICND2, or CCNA R/S Composite or any Cisco
exam at any of the Pearson VUE authorized testing centers. For
information, check
www.vue.com
or call 877-404-EXAM (3926).
To register for a Cisco exam, follow these steps:
1. Determine the number of the exam you want to take. (The ICND1
exam number is 100-105, ICND2 is 100-205, and CCNA R/S
Composite is 200-125.)
2. Register with the nearest Pearson VUE testing center. At this point,
you will be asked to pay in advance for the exam. At the time of this
writing, the ICND1 and ICND2 exams are $150, and the CCNA R/S
Composite exam is $250. The exams must be taken within one year of
payment. You can schedule exams up to six weeks in advance or as
late as the day you want to take it—but if you fail a Cisco exam, you
must wait five days before you will be allowed to retake it. If
something comes up and you need to cancel or reschedule your exam
appointment, contact Pearson VUE at least 24 hours in advance.
3. When you schedule the exam, you'll get instructions regarding all
appointment and cancellation procedures, the ID requirements, and
information about the testing-center location.
Tips for Taking Your Cisco Exams
The Cisco exams contain about 40-50 questions and must be completed
in about 90 minutes or less. This information can change per exam. You
must get a score of about 85 percent to pass this exam, but again, each
exam can be different.
Many questions on the exam have answer choices that at first glance look
identical—especially the syntax questions! So remember to read through
the choices carefully because close just doesn't cut it. If you get
commands in the wrong order or forget one measly character, you'll get
the question wrong. So, to practice, do the hands-on exercises at the end
of this book's chapters over and over again until they feel natural to you.
Also, never forget that the right answer is the Cisco answer. In many
cases, more than one appropriate answer is presented, but the correct
answer is the one that Cisco recommends. On the exam, you will always
be told to pick one, two, or three options, never "choose all that apply."
The Cisco exam may include the following test formats:
Multiple-choice single answer
Multiple-choice multiple answer
Drag-and-drop
Router simulations
Cisco proctored exams will not show the steps to follow in completing a
router interface configuration, but they do allow partial command
responses. For example,
show run, sho running
, or
sh running-config
would be acceptable.
Here are some general tips for exam success:
Arrive early at the exam center so you can relax and review your study
materials.
Read the questions carefully. Don't jump to conclusions. Make sure
you're clear about exactly what each question asks. "Read twice,
answer once," is what I always tell my students.
When answering multiple-choice questions that you're not sure about,
use the process of elimination to get rid of the obviously incorrect
answers first. Doing this greatly improves your odds if you need to
make an educated guess.
You can no longer move forward and backward through the Cisco
exams, so doublecheck your answer before clicking Next since you
can't change your mind.
After you complete an exam, you'll get immediate, online notification of
your pass or fail status, a printed examination score report that indicates
your pass or fail status, and your exam results by section. (The test
administrator will give you the printed score report.) Test scores are
automatically forwarded to Cisco within five working days after you take
the test, so you don't need to send your score to them. If you pass the
exam, you'll receive confirmation from Cisco, typically within two to four
weeks, sometimes a bit longer.
