<p style="margin:0px">Cisco CCDEs demonstrate expert-level knowledge and skills in network infrastructure design, ensuring their exceptional qualifications for addressing the most technically challenging design assignments. To earn this elite credential, candidates must pass the CCDE practical exam, organized into multiple design scenarios, each with its own type of network and set of challenging requirements. Each design scenario, in turn, is structured to encompass tasks in multiple domains, requiring the candidate to demonstrate expert level capabilities across the full network design lifecycle.</p><p style="margin:0px">&nbsp;</p><p style="margin:0px"><b>CCDE Study Guide</b> is Cisco's definitive CCDE preparation resource. Written and reviewed by CCDE engineers, it will help you to both improve your network design skills, and to systematically prepare for passing your exam. The authors cover a broad range of technologies, protocols, design options, and considerations showing how these can be integrated; how to choose and apply them based on each network's requirements and business goals; and how to fix broken designs that need to be optimized. Each section:</p><ul><li><div style="margin:0px">Highlights, discusses, and compares the limitations and advantages of key design options in terms of scalability, performance, flexibility, availability, complexity, and security</div></li><li><div style="margin:0px">Covers design aspects of different protocols and technologies, and shows how they map to different requirements</div></li><li><div style="margin:0px">Highlights drivers toward using these technologies -- whether for enterprise networks, service provider networks, or both</div></li><li><div style="margin:0px">Presents authoritative recommendations for further reading on each technology and concept</div></li></ul><p style="margin:0px"><b>CCDE Study Guide</b> concludes with two sample CCDE practical exams: one for service provider networks, and another for enterprise networks. Each provides a detailed scenario and background information, and guides you through the entire infrastructure design process: gathering and analyzing information; identifying issues; and proposing, developing, and applying your design.</p><p style="margin:0px">&nbsp;</p><p style="margin:0px">Wherever you stand in your CCDE journey, <b>CCDE Study Guide</b> will help you deepen your expertise, strengthen your confidence, earn your credential, and design more effective, higher-value networks.</p>
