Let Me Just Start Off by Saying That I Wish I Had Wendell Odom S Cisco Dqos Exam Certification

Cisco DQOS Exam Certification Guide Reviewer Name: Israel Lang, Systems Engineer Reviewer Certifications: CCNP and Cisco Voice Specialist

Let me just start off by saying that I wish I had Wendell Odom’s Cisco DQOS Exam Certification Guide a few months ago when I was studying for this exam. I had looked at a number of other Cisco Press and non-Cisco Press books and could not find one that adequately covered the topics in the exam. This one covers all of them and more.

The book starts off by listing all the exam topics that will be covered in both DQOS 9E0-601 and QOS 642-641 exams and then explains how to interpret those often nebulous expectations. Do not get me wrong. It does not give you a blow by blow of what is on the exam but rather informs you of how test makers come up with course objectives and a method to use in studying. I found this very helpful. In fact, I wish someone had taught me that as a freshman in college.

If you are familiar with Cisco Press Exam Certification Guides you will not be disappointed in the familiar format. Each chapter starts with an overview and “Do I Know This Already?” quiz. I always find these helpful in determining my level of knowledge on a particular subject and those areas I need to study.

It then proceeds to the meat of each chapter. They are filled with many useful diagrams and tables that do a wonderful job complimenting and expanding Odom’s covering of each chapter. There are plenty of switch and router configurations that also provide help in giving real life examples of how QoS is implemented.

Each chapter then wraps up with an excellent Foundation Summary and Q&A section. Answers to the questions are found in an appendix in the back of the book.

In general I found all of the topics covered as well, if not better, than the DQOS class I took to pass the test. In particular I found the first two chapters great in providing a great overview of QoS, it’s architectures and tools. I have used Odom’s example of bank teller lines, with a number of customers, to provide a way of explaining the difficult topic of QoS and it quickly resonates with them.

I also found the last two chapters on QoS Design and LAN QoS very useful. The LAN QoS chapter provides information on the 3550s and latest Modules/Supervisor Engine cards for the Catalyst 6500 and 4500/4000. I have already used this information as a resource on a project. The design chapter has also been useful in helping me “flesh out” customer’s goals and providing design recommendations based upon those goals.

In conclusion, I always feel that for a study guide to truly be useful, it must have some use after the exam. Wendell Odom’s Cisco DQOS Exam Certification Guide certainly does that well. It will not only be sufficient in providing you the information that you need to study for and pass the test, but it will certainly be useful as a quick reference guide on many of the topics covered. I plan on having it with me from the project planning stages to optimizing and troubleshooting stages (although if your good and follow his teachings on the former you probably will not have much of the latter). Thanks Wendell for another well written and useful book.
