CCDE Study Guide

CCDEs are recognized for their expert-level knowledge and skills in network infrastructure design. The deep technical networking knowledge that a CCDE brings ensures that they are well qualified to address the most technically challenging network infrastructure design assignments. In order to examine the CCDE candidate skills, knowledge and expertise the CCDE practical exam is divided into multiple design scenarios each of which has different type of network and set of requirements. In addition, each design scenario is structured using multiple domains and tasks that CCDE candidate has to go through in order to demonstrate expert level capabilities when dealing with full network design lifecycle.

CCDE Study Guide is written and reviewed by CCDE engineers and helps you to both improve your design skills and to study for and pass the CCDE exam. Network design is an art, combining broad technology knowledge and experience. This book covers a broad number of technologies, protocols and design options and considerations that can bring these aspects together and show how they can be used and thought about based on different requirements and business goals. Therefore, this book does not attempt to teach foundational technology knowledge, instead each section will:

• Highlight, discuss, and compare the limitations and advantages of the different design options in terms of scalability, performance, flexibility, availability, complexity , security etc. to simplify the job and help you understand what technology, protocol or design options should be selected and why, based on the business or application requirements or to fix a broken design that need to be optimized
•Cover design aspects of different protocols and technologies, and how they map with different requirements
• Highlight drivers toward using these technologies whether it is intended for enterprise or service provider network, depending on the topic and technology

Using a business-driven approach, CCDE Study Guide helps you analyze business and technical requirements and develop network designs that are based on these business needs and goals, taking into account both the technical and non-technical design constraints. The various “scenario-based” design examples discussed in this book will help you craft design approaches and requirements analysis on such topics as converged enterprise network architectures, service provider network architectures, and data centers. The book also addresses high availability, IPv6, multicast, QoS, security, and network management design considerations, presenting you with an in-depth evaluation of a broad range of technologies and environments.

Whether you are preparing for the CCDE exam or simply wish to gain better insight into the art of network design in a variety of environments, this book helps you learn how to think like an expert network designer in a business driven approach as well as analyze and compare the different design options, principles, and protocols based on different design requirements.
