Good book with tons of errors

It's a very good written book, but the shame is: too many errors in the book. And the worse part is, in ciscopress site, the errota didn't include any of them. The "Do I know This already Quiz" is terriblly written, and the answer keys are wrong all the time. Very funny the end of Chapter Q&A, same question, but the answer is one that's deemed to be wrong in the "Do I know this Already Quiz". The end of Chapter Q&A normally is the right answer.
Another ridiculous part is: For example, a question with for choices, A state this, B state that, D says both A and B correct. for this kind of question, the answer key sometime is ABD, sometime is AB, sometime is D. You got the point both A and B are right, but when you check the keys, you found you got wrong answer, it's super annoying.

Another major drawback of the questions is: too many trivial questions, like which model has how many interfaces etc. Is this really the purpose of this exam? and the answer seems to be yes. Because I just took the exam, passed it, and I saw a lot of such questions in real exam. Why should we mechanically memorize those models?
