You know Linux is going mainstream when the folks at CompTIA -- the “A+” people -- create an exam for it. And no wonder. Millions of companies are now saving a bundle with Linux servers. You might even encounter Linux workstations at your next company. While others have created Linux certifications before, CompTIA’s Linux+ certification may well be the best place to start -- and Linux+ In Depth covers every bit of it.
Linux+ is considered “entry level”: CompTIA figures you’ll have about six months’ experience with Linux by the time you take it. But don’t let that fool you: There’s a lot to know. Installation alone covers three chapters, from gathering pre-installation information through advanced RAID configuration -- and of course, troubleshooting.
You’ll find detailed coverage of Linux filesystems (from mount points to directory ownership and quotas); introductory BASH scripting; the boot process; the X Window System; and Linux processes. Linux+ In Depth next moves on to administering users, groups, and printers; system backup; software installation, performance optimization; and more. You’ll wrap up with an overview of Linux networking, including the rudiments of email and Windows file access.
The accompanying CD-ROM adds the powerful CertBlaster test engine and a large library of sample questions. You can practice in “Study Mode” (get instant feedback) or Certification Mode (randomly generated exams, complete with timed “countdowns”). It’ll also give you “Focus Drills” on questions you’ve missed, even make personalized study plans for you. Bill Camarda
