They will give out recommendations to for example keep certain values at their default settings, but will also explain what these settings do, and what the reasoning is behind this default value behavior. This means that you can follow their recommendation, but can also make an educated decision to change the setting in your setup. Either way, you now know why you changed or didn't change the setting, which makes for a better vSphere environment.
The book also gives you a lot of basic design principles, which can help tremendously when you are planning a new environment, and it also covers many of the advanced settings that allow you to better understand and "tweak" the inner workings of your setup. You might want to first test those advanced settings in a lab environment though. :-)
The way the book is written, the clear graphics, and the explanation behind reasonings or formulas used, make this a definite recommendation to not only get a better grip on the basic workings of HA and DRS, but also make it great as a travel companion and reference guide when you are on the road visiting customers (as a consultant perhaps) or changing/reviewing/renewing your environment!
The book is clearly written, a special emphasis has been made on making it understandable even for professionals like me who use vSphere daily yet do not manage huge production environments. The book goes to great lengths to explain all possible scenarios and I found answers to all my questions. Not only sections cover HOW the technology works, but the authors go as far as explaining the way the algorithms are working, which will satisfy the curiosity of everyone.
Finally, as a cherry on top of the cake, the graphs and workflows are done with great taste and are pleasant to look at (The DPM throttle one is great!). Kindle owners such as me may find them a bit dull on grayscale compared to what I've seen of the color printed version on Duncan Epping's blog.
A great, concise and useful technical book, that every virtualization administrator/architect should own.
This book is certainly intended for a specific audience of VMware professionals although even those who do not feel the need to really get into the deep dive can benefit greatly. Frank and Duncan regular provide "Basic Design Principles" at the end of most sections that should guide the reader on how to make their decision while knowing that the information needed for reinforcing and understanding their decision can be found in preceding paragraphs. One disappointment in this edition however was the lack of appendices found in the original HA & DRS Technical Deep Dive which included a breakdown of all of the "Basic Design Principles" and Advanced Settings. This can be forgiven I believe since a quick look at the table of contents for the component you're interested in means you can confident locate their recommendations.
The complete explanations provide the reader all of the information needed to make informed decisions about their environment with excellent diagrams to provide strong visual reinforcements. I personally found a few components not initially easily understood quickly brought to light through their full-color visualizations. If you are weighing between the color or black-and-white print versions you will be well served to go color. I purchased the toddler-proof Kindle version which also provides the full color diagrams on my iPad, iPhone, and PC.

I especially find value in the explanations on customizable settings throughout the book and how to properly address them. More importantly they let you know when it may be best to just leave things at default and why those defaults settings might have been chosen by VMware.
Not ready for vSphere 5? No worries since throughout the book the authors regularly explain any difference between version 5 and its predecessors. I will suggest that if at time of reading you are preparing for one of the VCAP4 certifications you may wish to read this carefully and make sure you understand the vSphere 4 architecture properly. Otherwise feel confident that once you hit page 348 you will have a comprehensive and well organized explanation of VMware's vSphere 5 clustering architecture by two of the VMware communities most respected gurus.
