Excerpts

Introduction Introduction Welcome to the world of CCNA Voice! As technology continues to evolve, the realm of voice, which was traditionally kept completely separate from data, has now begun to merge with the data network. This brings together two different worlds of people: data technicians--historically accustomed to working with routers, switches, servers, and the like--and voice technicians, historically accustomed to working with PBX systems, digital handsets, and trunk lines. Regardless of your background, one of the primary goals of the new CCNA Voice certification is to bridge these two worlds together. In June 2008, Cisco announced new CCNA specialties, including CCNA Security, CCNA Wireless, and CCNA Voice. These certifications, released 10 years after the initial CCNA, represent Cisco's growth into new and emerging industries. Certification candidates can now specialize in specific areas of study. Figure I.1 shows the basic organization of the certifications and exams used to achieve your CCNA Voice certification. Figure I.1 Cisco Certifications and CCNA Voice Certification Path As you can see from Figure I.1, a traditional CCNA certification is a prerequisite before you venture into the CCNA Voice certification. As of June 2009, the CCNA Voice certification will become a prerequisite before you are able to pursue the Cisco Certified Voice Professional (CCVP) certification. Goals and Methods The most important and somewhat obvious goal of this book is to help you pass the Implementing Cisco IOS Unified Communications (IIUC) exam (640-460). In fact, if the primary objective of this book were different, then the book's title would be misleading. The methods used in this book to help you pass the IIUC exam are designed to also make you much more knowledgeable about how to do your job. This book uses several key methodologies to help you discover the exam topics that you need to review in more depth, 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 by memorization, but helps you truly learn and understand the topics. The CCNA Voice exam is the foundation for many of the Cisco professional certifications, and it would be a disservice to you if this book did not help you truly learn the material. Therefore, this book will help you pass the CCNA Voice exam by using the following methods: Helping you discover which test topics you have not mastered Providing explanations and information to fill in your knowledge gaps Supplying exercises and scenarios 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-ROM. In addition, this book uses quite a different style from typical certification-preparation books. The newer Cisco certification exams have adopted a style of testing that essentially says, "If you don't know how to do it, you won't pass this exam." This means that most of the questions on the certification exam will require you to deduce the answer through reasoning or configuration rather than just memorizing facts, figures, or syntax from a book. To accommodate this newer testing style, the authors have written this book as a "real world" explanation of Cisco VoIP topics. Most concepts are explained using real-world examples rather than showing tables full of syntax options and explanations, which are freely available on Cisco.com. As you read through this book, you will definitely get a feeling of, "This is how I can dothis," which is exactly what you need for the newer Cisco exams. Who Should Read This Book? The purpose of this book is twofold. The primary purpose is to tremendously increase your chances of passing the CCNA Voice certification exam. The secondary purpose is to provide the information necessary to deploy a VoIP solution using Cisco Unified Communication Manager Express (CME) or the Smart Business Communications System (SBCS). Cisco's new exam approach provides an avenue to write the book with both a real-world and certification-study approach at the same time. As you read through this book and study the configuration examples and exam tips, you will have a true sense of understanding how you could deploy a VoIP system, while at the same time feeling equipped to pass the CCNA Voice certification exam. Strategies for Exam Preparation Strategies for exam preparation will vary depending on your existing skills, knowledge, and equipment available. Of course, the ideal exam preparation would consist of building a small voice lab with a Cisco Unified Communications Manager Express 2801 Integrated Services Router and Cisco Unity Express capabilities, a switch, and a few IP phones, which you could then use to work through the configurations as you read through this book. However, not everyone has access to this equipment, so the next best step you can take is to read through the chapters in this book, jotting notes down with key concepts or configurations on a separate notepad. Each chapter begins with a "Do I Know This Already?" quiz designed to give you a good idea of the chapter's content and your current understanding of it. In some cases, you might already know most of or all the information covered in a given chapter. After you have read through the book, have a look at the current exam objectives for the CCNA Voice exam listed on Cisco.com (http://www.cisco.com/certification). If there are any areas shown in the certification exam outline that you would still like to study, find those sections in the book and review them. When you feel confident in your skills, attempt the practice exam included on the CD with this book. As you work through the practice exam, note the areas where you lack confidence and review those concepts or configurations in the book. After you have reviewed the areas, work through the practice exam a second time and rate your skills. Keep in mind that the more you work through the practice exam, the more familiar the questions will become, so the practice exam will become a less accurate judge of your skills. After you have worked through the practice exam a second time and feel confident with your skills, schedule the real IIUC (640-460) exam through Vue (http://www.vue.com). You should typically take the exam within a week from when you consider yourself ready to take the exam, so that the information is fresh in your mind. Keep in mind that Cisco exams are very difficult. Even if you have a solid grasp of the information, there are many other factors that play into the testing environment (stress, time constraints, and so on). If you pass the exam on the first attempt, fantastic! If not, know that this happens commonly. The next time you attempt the exam, you will have a major advantage: you have experienced the exam first-hand. Although future exams may have different questions, the topics and general "feel" of the exam will remain the same. Take some time to study areas from the book where you felt weak on the exam. Retaking the exam the same or following day from your first attempt is a little aggressive; instead, schedule to retake it within a week, while you are still familiar with the content. 640-460 IIUC Exam Topics Table I.1 lists the exam topics for the 640-460 IIUC exam. This table also lists the book parts in which each exam topic is covered. Table I.1 640-460 IIUC Exam Topics
