Appendix J. Additional Scenarios

Each chapter of this book focuses on a small set of related topics so that you can more easily digest the material. However, the CCNA exams require that you be able to apply a relatively wide set of topics to answer an individual question. Oftentimes, the skills for applying the wide-ranging topics to solve a single problem can be best learned through experience. Even so, many CCNA candidates may not get on-the-job experience with all technologies on the CCNA exams, and some may not get any experience. The scenarios included in this book attempt to provide some of the same exam-preparation benefits as would on-the-job experience.

You can think of each scenario as a slice of what you might do in a real networking job, with an experienced mentor walking through the solutions with you after you have tried to solve a particular problem. Each scenario presents a variety of internetwork topologies, concepts, commands, and protocols, with a variety of tasks. By reading over the scenarios, and doing the exercises and answering the open-ended questions listed with the scenarios, you can practice applying different knowledge areas to the same scenario. By reading the answers, you can see at least one possible solution to the problems listed in the scenario, along with the reasons why that solution makes sense.
