INTRODUCTION
Congratulations on your decision to become Linux+ certified! By purchasing this book,
you??™ve taken the first step toward earning one of the hottest certifications around.
Being Linux+ certified provides you with a distinct advantage in today??™s IT job market.
When you obtain your Linux+ certification, you prove to your employer, your co-workers, and to
yourself that you truly know your stuff with Linux.
This is a big issue. Over the years, I??™ve had the opportunity to interview a number
of job applicants for open positions in my organization. I learned early on that you
can??™t rely on the Skills and Knowledge section of an applicant??™s r?©sum?© to get an
accurate picture of what they can and can??™t do. Case in point: Back in the late 1990s
my group had a position open that required an exceptionally strong background in
computer hardware and networking. The job posting listed ???extensive background
with computers and networking??? as one of the requirements for the position.
