Бросил все другие книги, и читаю только CCNA Exploration. Это самое лучшее учебное пособие для подготовки к сертификационному экзамену CCNA. Сейчас мне от всей души жаль те несколько десятков USD, которые были потрачены на оригинальные книги Cisco Press и Sybex. Все также нравятся книги в бумажном варианте, но наличие в бесплатном доступе такого ценного материала сводит на нет желание их приобретать. В этой статье есть ссылка на онлайн курс CCNA Exploration. Ниже в этой статье приведено оглавление курса для того, чтобы легко найти нужную часть.
This course introduces the architecture, structure, functions, components, and models of the Internet and other computer networks. It uses the OSI and TCP layered models to examine the nature and roles of protocols and services at the application, network, data link, and physical layers. The principles and structure of IP addressing and the fundamentals of Ethernet concepts, media, and operations are introduced to provide a foundation for the curriculum. Labs use a “model Internet” to allow students to analyze real data without affecting production networks. Packet Tracer (PT) activities help students analyze protocol and network operation and build small networks in a simulated environment. At the end of the course, students build simple LAN topologies by applying basic principles of cabling; performing basic configurations of network devices, including routers and switches; and implementing IP addressing schemes.
