Negative Positive
Title: Useless on the test, but good general reference
Review: I have been in tech support for a decade, and picked up this book to cover the stuff my job does not. I drilled down on it, studied it, passed its practice tests with 80-90%And it was utterly USELESS when I showed up at the test site. It does not cover the run-line commands, does not cover nearly enough on installation questions or protocols. It's a great book for everything BUT what you need to pass.
Is the review positive or negative?
