101 Labs – Linux LPIC1 is out

I am the Technical Editor for the new Paul Browning book, 101 Labs – Linux LPIC1.

Experts agree that we retain only 10% of what we read but 90% of what we do. Perhaps this explains why the global pass rate for most IT exams is a ghastly 40%.

101 Labs’ mission is to turn you into an IT expert by doing instead of reading. Using free software and free trials, the labs take you by the hand and walk you through every aspect of the protocols and technologies you will encounter in your IT career.

Configuration tips and tricks are shared with you as well as how to avoid the common mistakes many novice engineers make, which can quickly become career-ending.

You can get a free preview or buy the ebook below.

101 Labs – Linux LPIC1 takes you through the beginner exam syllabus, the LPI Linux Essentials in case you are a novice and want to learn the basics of Linux or simply just brush up your skills. You then tackle all the main LPIC1 topics broken into the two exams 101 and 102.
