Designing for Cisco Internetwork Solutions (DESGN) (Authorized CCDA Self-Study Guide) (Exam 640-863)
-
Preparing for the practical portion of your Cisco Certified Internetwork Engineer (CCIE) examination, in which you have to configure and troubleshoot networks on Cisco equipment in a testing lab, can be scary. There's simply so much the test proctor can throw at you, and you have to be prepared for it all. CCIE Practical Studies Volume 1 does a fantastic job of preparing you for much of what you can expect to see on the first day of your CCIE lab exam (when you build a system to specifications). Karl Solie, a CCIE himself, approaches each subject on the CCIE syllabus first with a quick academic overview ("here's what frame relay", for instance, "is for, and here's how Cisco equipment thinks of it"). That gives way to a series of examples ("here's a typical set of customer requirements, and here are the IOS commands and configuration files that satisfy them"). Finally, a series of subject-specific lab exercises (which are shorter than a typical day-long CCIE assignment) drill you on the Cisco skills related to the technology at hand. Solie explains how he'd solve the lab--in wonderful detail--immediately after the pages that describe these small lab tasks.At the end of the book, you'll find five full-scale CCIE labs, very similar to the ones you'll have to complete in eight-and-a-half hours on test day. There are instructions on how to pre-stage your equipment (as the exam proctor would normally do), and what you need to accomplish. You can time yourself on these labs and get a very good idea of your preparedness. Solie could make the next edition of this book better by devoting even more discussion to the troubleshooting techniques appropriate to different kinds of systems. Problems inevitably crop up in CCIE configurations, and there's rarely time to start over in the lab. Regardless, provided you have the equipment and discipline required to work through his exercises independently, this book is a better deal than almost any commercial training course. --David Wall

Of the preparation guides available for the Cisco Certified Design Associate exam (640-861), CCDA: Cisco Certified Design ssociate Study Guide comes out on top. Authors Todd Lammle and Donald Porter clearly explain what you need to know, both to pass the exam and to prove yourself a competent network technician once on the job. Some of the material that appears in these pages--a table listing various Cisco router product lines, their capabilities, and suitable applications for them, to cite one example--makes great reading, and will prove useful long after the exam is over.The authors' presentation style uses text to great effect, explaining potentially confusing topics with clear, fact-rich prose that rewards close attention from the reader. There are plenty of helpful conceptual diagrams (illustrating network segmentation with a bridge, for example) and flow charts (a good one illustrates packet-switching logic) as well.
It's sometimes possible to forget that this is an exam preparation aid, but realistic problems and multiple-choice review questions bring readers back to the task at hand. Elaborate solutions to the problems and quick answers to the review questions appear in the back of this book (along with an excellent, extensive glossary), but the answer key would be more helpful if it included brief discussions explaining the reasoning behind the correct answers. --David Wall
Topics covered: All proscribed elements of the CCDA exam (640-861), including the Open Systems Interconnect (OSI) reference model, Ethernet, network topologies, network protocols, routing, bridging, switching, and the fundamentals of Cisco hardware and software products.

A typical entry in Cisco's Certification Training Series, Designing Cisco Networks is jammed with good technology and business information. Intended as an accompaniment to an eponymous course that is part of the Cisco Certified Design Associate certificate program, the book's goal is to provide a blueprint for designing networks for small and medium- sized companies. And it does a good job of that, even though it's never clear how the editor, the technical reviewers, or Cisco define that particular market segment.Because the authors assume a fairly sophisticated level of networking knowledge, they buzz through the basics--technologies, protocols and devices--in the first chapter. This section, and the rest of the book for that matter, is characterised by pithy phrasing that leaves no room for interpretation, which is a blessing for this type of publication. For example, local area networks (LANs) are given these attributes: "fast, belongs to you, is there all the time."
Later sections deal with the steps involved in characterising an existing network and determining how to update it for the customer's needs. Obvious but good points are made, such as identifying technological and business-related bottlenecks. In addition, readers are pointed to a series of tools, such as NetFlow and CiscoWorks, that can help with network assessment and design. From there, the inner workings of developing a network technology are explored, as is the challenge of figuring out which protocols, devices and management tools and strategies make the most sense for the environment. Case studies and sample CCDA test questions are woven throughout the book and it wraps up with 12 appendices on topics such as PIX firewalls and DNS spoofing, plus a glossary. --Sarah L. Roberts-Witt
