CCDA Exam Certification Guide, Second Edition Reviewer Name: David Mahler, Technical Trainer/Network Administrator Rating: **** out of ***** The CCDA Exam Certification Guide (Anthony Bruno, Cisco Press, ISBN 1-58720-076-7) is a good choice for CCDA candidates from a large range of experience and backgrounds. As a technical trainer I look for texts that present material in a way that is clear to understand and emphasizes recall and review. I look for clear diagrams and charts that are relevant to their context and aid understanding of difficult concepts. This text meets all these objectives well. The text is labeled as a “Self-Study” guide. However, I would recommend it regardless of whether the reader is receiving formal training or is studying independently. This is a good text for someone who has completed the CCNA program and wishes to broaden his or her knowledge by going for the CCDA Many of my CCNA students read a chapter of their text and wrongly assume they have acquired enough knowledge about a topic. With a few review questions they find they understand less than they initially thought, but they know what is lacking. Anthony Bruno’s text gives so many opportunities for review. Review questions and summaries are included at the beginning and end of every chapter. Bruno’s text includes “Do I Know This Already?” quizzes at the beginning of every chapter and “Q&A” at the end of every chapter. “Do I Know This Already?” gives readers a good idea of their strengths/weaknesses in knowledge before starting a chapter. It even allows for skimming or skipping chapters based on solid understanding of a concept. The Q&A at the end of every chapter allows one to test understanding and review what didn’t quite sink in the first time. The only drawback to these sections is that there are several errors, which are somewhat frustrating and can confuse readers. There is also a CD-ROM that provides an exam simulation for final preparation for the CCDA. This saves so much time in searching the web/other texts for practice questions. The explanations of concepts are generally high quality. However, there are areas that assume a level of understanding that not all CCDA candidates have or are expected to have. Some explanations could stand to be a bit clearer and contain errors. However, a little on-line research can go a long way to fill in some gaps a reader may have. All in all it cuts the middle between an experienced candidate and someone new to networking well. The illustrations and charts are first-rate. I always find Cisco Press’ illustrations to be superior to other texts in clarity and relevance to the text. Charts are included every time they need to be to aid understanding. The most important charts are reproduced in the summaries of every chapter. This is something I always find lacking in non-Cisco Press texts. I would definitely recommend this text to my students going for the CCDA. Someone who reads the text, goes through all the review questions, and conducts on-line research/study should be well prepared for the CCDA. I wouldn’t recommend this for someone who has not already gone through a CCNA program or has CCNA level experience (just do that first!). On a scale of 1-5, I’d rate this text a 4.
