Introduction

Introduction

Congratulations on your decision to pursue a Cisco Certification! If you're reading far enough to look at the introduction to this book, you likely already have a sense of what you ultimately would like to achieve—the Cisco CCNA Security certification. Achieving Cisco CCNA Security certification requires that you pass the Cisco IINS (640-553) exam. Cisco certifications are recognized throughout the networking industry as a rigorous test of a candidate's knowledge of and ability to work with Cisco technology. Through its quality technologies, Cisco has garnered a significant market share in the router and switch marketplace, with more than 80 percent market share in some markets. For many industries and markets around the world, networking equals Cisco. Cisco certification will set you apart from the crowd and allow you to display your knowledge as a networking security professional.

Historically speaking, the first entry-level Cisco certification is the Cisco Certified Network Associate (CCNA) certification, first offered in 1998.

With the introduction of the CCNA Security certification, Cisco has for the first time provided an area of focus at the associate level. The CCNA Security certification is for networking professionals who work with Cisco security technologies and who want to demonstrate their mastery of core network security principles and technologies.

Format of the IINS Exam

The 640-553 IINS exam follows the same general format of other Cisco exams. When you get to the testing center and check in, the proctor gives you some general instructions and then takes you into a quiet room with a PC. When you're at the PC, you have a few things to do before the timer starts on your exam. For instance, you can take a sample quiz, just to get accustomed to the PC and the testing engine. If you have user-level PC skills, you should have no problems with the testing environment. Additionally, Chapter 16 points to a Cisco website where you can see a demo of the actual Cisco test engine.

When you start the exam, you are asked a series of questions. You answer the question and then move on to the next question. The exam engine does not let you go back and change your answer. When you move on to the next question, that's it for the earlier question.

The exam questions can be in one of the following formats:

  • Multiple-choice (MC)

  • Testlet

  • Drag-and-drop (DND)

  • Simulated lab (Sim)

  • Simlet

The first three types of questions are relatively common in many testing environments. The multiple-choice format simply requires that you point and click a circle beside the correct answer(s). Cisco traditionally tells you how many answers you need to choose, and the testing software prevents you from choosing too many answers. Testlets are questions with one general scenario, with multiple MC questions about the overall scenario. Drag-and-drop questions require you to click and hold, move a button or icon to another area, and release the mouse button to place the object somewhere else—typically in a list. For example, to get the question correct, you might need to put a list of five things in the proper order.

The last two types both use a network simulator to ask questions. Interestingly, these two types allow Cisco to assess two very different skills. Sim questions generally describe a problem, and your task is to configure one or more routers and switches to fix the problem. The exam then grades the question based on the configuration you changed or added. Interestingly, Sim questions are the only questions that Cisco (to date) has openly confirmed that partial credit is given for.

The Simlet questions may well be the most difficult style of question on the exams. Simlet questions also use a network simulator, but instead of answering the question by changing the configuration, the question includes one or more MC questions. The questions require that you use the simulator to examine the current behavior of a network, interpreting the output of any show commands that you can remember to answer the question. Whereas Sim questions require you to troubleshoot problems related to a configuration, Simlets require you to analyze both working networks and networks with problems, correlating show command output with your knowledge of networking theory and configuration commands.

What's on the IINS Exam?

Cisco wants the public to know both the variety of topics and the kinds of knowledge and skills that are required for each topic, for every Cisco certification exam. To that end, Cisco publishes a set of exam topics for each exam. The topics list the specific subjects, such as ACLs, PKI, and AAA, that you will see on the exam. The wording of the topics also implies the kinds of skills required for that topic. For example, one topic might start with "Describe...", and another might begin with "Describe, configure, and troubleshoot...". The second objective clearly states that you need a thorough and deep understanding of that topic. By listing the topics and skill level, Cisco helps you prepare for the exam.

Although the exam topics are helpful, keep in mind that Cisco adds a disclaimer that the posted exam topics for all its certification exams are guidelines. Cisco makes an effort to keep the exam questions within the confines of the stated exam topics. I know from talking to those involved that every question is analyzed to ensure that it fits within the stated exam topics.

IINS Exam Topics

Table I-1 lists the exam topics for the 640-553 IINS exam. Although the posted exam topics are not numbered at Cisco.com, Cisco Press does number the exam topics for easier reference. Notice that the topics are divided among nine major topic areas. The table also notes the part of this book in which each exam topic is covered. Because it is possible that the exam topics may change over time, it may be worthwhile to double-check the exam topics as listed on Cisco.com (http://www.cisco.com/go/certification). If Cisco later adds exam topics, you may go to http://www.ciscopress.com and download additional information about the newly added topics.

IINS Course Outlines

Another way to get some direction about the topics on the exams is to look at the course outlines for the related courses. Cisco offers one authorized CCNA Security-related course: Implementing Cisco IOS Network Security (IINSv1.0). Cisco authorizes Certified Learning Solutions Providers (CLSP) and Certified Learning Partners (CLP) to deliver these classes. These authorized companies can also create unique custom course books using this material, in some cases to teach classes geared toward passing the 640-553 IINS exam.

About the CCNA Security Official Exam Certification Guide

As mentioned earlier, Cisco has outlined the topics tested on the 640-553 IINS exam. This book maps to these topic areas and provides some background material to give context and to help you understand these topics.

This section lists this book's variety of features. A number of basic features included in this book are common to all Cisco Press Official Exam Certification Guides. These features are designed to help you prepare to pass the official certification exam, as well as help you learn relevant real-world concepts and procedures.

Objectives and Methods

The most important and somewhat obvious objective of this book is to help you pass the 640-553 IINS exam. In fact, if the primary objective of this book were different, the book's title would be misleading! However, the methods used in this book to help you pass the exams are also designed to make you much more knowledgeable about how to do your job.

This book uses several key methodologies to help you discover the exam topics on which you need more review, to help you fully understand and remember those details, and to help you prove to yourself that you have retained your knowledge of those topics. So, this book does not try to help you pass the exams only by memorization, but by truly learning and understanding the topics. The CCNA Security certification is the foundation of the professional level Cisco certification in security, the CCSP, so it is important that this book also help you truly learn the material. This book is designed to help you pass the CCNA Security exam by using the following methods:

  • Helping you discover which exam topics you have not mastered

  • Providing explanations and information to fill in your knowledge gaps

  • Supplying exercises that enhance your ability to recall and deduce the answers to test questions

  • Providing practice exercises on the topics and the testing process via test questions on the CD
