Most technical books have a certain level of innacuracy due to the fact that nobody's perfect. This book is riddled with them. Most of them are cases of a schizophrenic book contradicting itself. About half of the errors can be found at Sybex's website. A person serious about studying for any certification should get study guides from at least two different perspectives. By this I mean two different books, not one book with two different personalities.Sybex is well known for high quality publications. How did this one get past your technical editors? It only seems to get worse with newer revisions.
