Negative Positive
Title: The only book you need (as well as practical experience)
Review: I would say the book is sufficient for passing the exam. However, practice is also necessary and I read the book through twice as this was necessary to make all the pieces fit together. In my exam I was hardly asked about IP addresses, classes or subnets... amazing (and I knew them really well). I would recommend people to get further information on RAS as the book does not cover this subject sufficiently.
Is the review positive or negative?
