Ccie Fundamentals

It is impossible to understand the history of modern Europe without some knowledge of the Weimar Republic. The brief fourteen-year period of democracy between the Treaty of Versailles and the advent of the Third Reich was marked by unstable government, economic crisis and hyperinflation and the rise of extremist political movements. At the same time, however, a vibrant cultural scene flourished, which continues to influence the international art world through the aesthetics of Expressionism and the Bauhaus movement. In the fields of art, literature, theatre, cinema, music and architecture – not to mention science – Germany became a world leader during the 1920s, while her perilous political and economic position ensured that no US or European statesman could afford to ignore her. Incorporating original research and a synthesis of the existing historiography, this book will provide students and a general readership with a clear and concise introduction to the history of the first German Republic.

Cisco IOS 12.0 Bridging and IBM Network Solutions contains configuration scenarios and command reference information that demonstrate bridging and IBM networking options. Written for network administrators, this guide explores transparent and source-route transparent bridging, Source-Route Bridging (SRB), data link switching plus (DLSw+), serial tunnel and block serial tunnel, SDLC and LLC2 parameters, and advanced peer-to-peer networking.

Data Center Virtualization Fundamentals For many IT organizations, today’s greatest challenge is to drive more value, efficiency, and utilization from data centers. Virtualization is the best way to meet this challenge. Data Center Virtualization Fundamentals brings together the comprehensive knowledge Cisco professionals need to apply virtualization throughout their data center environments. Leading data center expert Gustavo A. A. Santana thoroughly explores all components of an end-to-end data center virtualization solution, including networking, storage, servers, operating systems, application optimization, and security. Rather than focusing on a single product or technology, he explores product capabilities as interoperable design tools that can be combined and integrated with other solutions, including VMware vSphere. With the author’s guidance, you’ll learn how to define and implement highly-efficient architectures for new, expanded, or retrofit data center projects. By doing so, you can deliver agile application provisioning without purchasing unnecessary infrastructure, and establish a strong foundation for new cloud computing and IT-as-a-service initiatives. Throughout, Santana illuminates key theoretical concepts through realistic use cases, real-world designs, illustrative configuration examples, and verification outputs. Appendixes provide valuable reference information, including relevant Cisco data center products and CLI principles for IOS and NX-OS. With this approach, Data Center Virtualization Fundamentals will be an indispensable resource for anyone preparing for the CCNA Data Center, CCNP Data Center, or CCIE Data Center certification exams.
