The Course Booklet is a basic, economical paper-based resource to help you succeed with the Cisco Networking Academy online course.
The goal is to develop an understanding of how switches are interconnected and configured to provide network access to LAN users. This course also teaches how to integrate wireless devices into a LAN. The specific skills covered in each chapter are described at the start of each chapter. More than just information This computer-based learning environment is an important part of the overall course experience for students and instructors in the Networking Academy.
These online course materials are de- signed to be used along with several other instructional tools and activities. Schools, colleges, universities and other entities in over countries participate in the program. The material in this course encompasses a broad range of technologies that facilitate how people work, live, play, and learn by communicating with voice, video, and other data.
Networking and the Internet affect people differently in different parts of the world. Although we have worked with instructors from around the world to create these materials, it is important that you work with your instructor and fellow students to make the material in this course applicable to your local situation.
Keep in Touch These online instructional materials, as well as the rest of the course tools, are part of the larger Networking Academy. There you will obtain access to the other tools in the program such as the assessment server and student grade book , as well as informational updates and other relevant links.
It is important to realize, however, that the instructional materials and the instructor can only facilitate the process. You must make the commitment yourself to learn new skills. Below are a few suggestions to help you learn and grow. Take notes. Professionals in the networking field often keep Engineering Journals in which they write down the things they observe and learn.
Taking notes is an important way to help your understanding grow over time. Think about it. The course provides information both to change what you know and what you can do.
Stop and ask questions when you are confused. Try to find out more about topics that interest you. If you are not sure why something is being taught, consider asking your instructor or a friend. Think about how the different parts of the course fit together. Learning new skills requires practice.
We believe this is so important to e-learning that we have a special name for it. We call it e-doing. Practice again. Just like learning any new skill like a sport, game, or language, learning a professional skill requires patience and repeated practice before you can say you have truly learned it.
The online instructional materials in this course provide opportunities for repeated practice for many skills. Take full advantage of them. You can also work with your instructor to extend Packet Tracer, and other tools, for additional practice as needed. Teach it. Teaching a friend or colleague is often a good way to reinforce your own learning.
To teach well, you will have to work through details that you may have overlooked on your first reading. Conversations about the course material with fellow students, colleagues, and the instructor can help solidify your understanding of networking concepts.
Make changes as you go. The course is designed to provide feedback through interactive activities and quizzes, the online assessment system, and through interactions with your instructor. You can use this feedback to better understand where your strengths and weaknesses are.
If there is an area that you are having trouble with, focus on studying or practicing more in that area. Seek additional feedback from your instructor and other students.
Explore the world of networking This version of the course includes a special tool called Packet Tracer 4. Packet Tracer is a net- working learning tool that supports a wide range of physical and logical simulations.
It also pro- vides visualization tools to help you to understand the internal workings of a network. The Packet Tracer activities included in the course consist of network simulations, games, activi- ties, and challenges that provide a broad range of learning experiences. Create your own worlds You can also use Packet Tracer to create your own experiments and networking scenarios. We hope that, over time, you consider using Packet Tracer — not only for experiencing the activities in- cluded in the course, but also to become an author, explorer, and experimenter.
This integration may also work on other operating systems using Windows emulation. The goal is to develop an understanding of how a switch communicates with other switches and routers in a small- or medium-sized business network to implement VLAN segmentation. This course focuses on Layer 2 switching protocols and concepts used to improve redundancy, propagate VLAN information, and secure the portion of the network where most users access net- work services.
Switching technologies are relatively straightforward to implement; however, as with routing, the underlying protocols and algorithms are often quite complicated. This course will go to great lengths to explain the underlying processes of the common Layer 2 switching technologies.
The better the underlying concepts are understood, the easier it is to implement, verify, and trou- bleshoot the switching technologies. Each switching concept will be introduced within the context of a single topology for each chapter.
The individual chapter topologies will be used to explain protocol operations as well as providing a setting for the implementation of the various switching technologies.
The labs and Packet Tracer activities used in this course are designed to help you develop an un- derstanding of how to configure switching operations while reinforcing the concepts learned in each chapter. In particular, hierarchical network design utilizing the core-distribution-access layer model is introduced and referenced throughout the remainder of the course.
Chapter 2 Basic Switch Concepts and Configuration — Chapter 2 introduces switch forward- ing methods, symmetric and asymmetric switching, memory buffering, and Layer 2 and Layer 3 switching.
An integral role of a switch administrator is to maintain a secure network; to this end, you learn to configure various passwords on the switch as well as SSH to mitigate common security attacks. You learn to configure, verify, and troubleshoot VTP imple- mentations. The configuration of STP is fairly straightforward, but the underlying processes are quite complicated. IEEE RSTP convergence time is approximately five times faster than conver- gence with RSTP introduces several new concepts, such as link types, edge ports, alter- nate ports, backup ports, and the discarding state.
You will learn to configure both the original IEEE You learn the various methods of inter-VLAN routing. You learn to implement inter-VLAN routing in the router-on-a-stick topology, where a trunk link connects a Layer 2 switch to a router configured with logical subinterfaces paired in a one-to-one fashion with VLANs. Chapter 7 Basic Wireless Concepts and Configuration — Wireless LAN standards are evolving for voice and video traffic, with newer standards being supported with quality of service.
An ac- cess point connects to the wired LAN provides a basic service set to client stations that associate to it. Enterprise solutions such as WPA2 and End users have to configure a wireless NIC on their client stations which communicates with and asso- ciates to a wireless access point. When configuring a wireless LAN, you should ensure that the de- vices have the latest firmware so that they can support the most stringent security options.
Consequently, a properly designed LAN is a fundamental requirement for doing business today. You must be able to recognize a well-designed LAN and select the ap- propriate devices to support the network specifications of a small- or medium-sized business.

Затем взял ботинки и постучал каблуками по столу, точно вытряхивая камешек. Просмотрев все еще раз, он отступил на шаг и нахмурился. - Какие-то проблемы? - спросил лейтенант.
Стратмор ответил ей тоном учителя, терпеливого и умеющего держать себя в руках: - Да, Сьюзан, ТРАНСТЕКСТ всегда найдет шифр, каким бы длинным он ни. - Он выдержал длинную паузу. - Если только… Сьюзан хотела что-то сказать, но поняла, что сейчас-то Стратмор и взорвет бомбу. Если только - .
Потом закрыл глаза и глубоко вздохнул. Беккер не сразу почувствовал, что его кто-то подталкивает. Подняв глаза, он увидел старика с усыпанным родинками лицом, который стоял перед ним, намереваясь пройти.
Неужели. - Да. После того как я вскрыл алгоритм Попрыгунчика, он написал мне, что мы с ним братья по борьбе за неприкосновенность частной переписки. Сьюзан не могла поверить своим ушам.
Джабба посмотрел на ВР. - Около двадцати минут.
