    Linux Foundation certifications are taking off | 1Z0-403 true Questions and VCE practice Test

    According to a study conducted earlier this year by Dice, the tech career site, 93 percent of hiring managers are looking to employ Linux professionals. If you want one of those jobs, a much way to extend your chances is to retract to human resources with one of the Linux Foundation's new certifications as a Certified SysAdmin (LFCS) or Certified Engineer (LFCE).


    The fact that Linux jobs are passionate has not gone unnoticed. According to Dan Brown, The Linux Foundation's PR & Marketing Manager, "The Linux Foundation’s Intro to Linux Massive Open Online Course (MOOC) , which can serve with basic prep for the LF Certified SysAdmin Exam, has had over 270,000 registrations from 100+ countries." That has made this online class the biggest MOOC ever.

    While these Linux Foundation certifications are designed to live complementary to the lower-level Linux Professional Institute (LPI) certifications, they're more comparable to high-level certifications such as Red Hat's Red Hat Certified System Administrator (RHCSA) in that they're not simple to pass. 

    The exams are everybitof conducted from a Linux shell — no easy-to-use graphical tools here! — and enjoy a pass-rate of below 60 percent. As tough as they are, however, 80 percent of the people who've taken the exam would recommend seeking the certification to a friend.

    Scared of those odds? Well, I can't weakness you, but there's now a free exam prep guide to serve you Get ready and build up your courage.

    In addition, The Linux Foundation's CMO Amanda McPherson, recently blogged, "When you note up for the exam you can set the date to buy it well in the future or you can pick a date when you’re ready. It’s not an instant process since a proctor has to live scheduled and so on. They hearten you to note up for the exam and Get your testing date scheduled so you can Get your preparation underway. You enjoy 12 months from the time you note up to buy the exam, so you can give yourself as much time as needed to prepare and you’ll live in the system for updates or changes."

    The Linux Foundation will moreover live publishing stories about people's experiences with the exams. The first of these tells the tale of Will Sheldon, an IT manager for open source consulting company Appnovation Technologies, who took the LFCE exam and passed. If you enjoy hearing about how other people faced the identical situation you're getting ready for, stories enjoy Will's can live helpful.

    Unlike the Red Hat exams, which are Red Hat Enterprise Linux (RHEL)-specific, there are three varieties of Linux Foundation exams: Ubuntu, CentOS, and openSUSE. So far, half of the exam takers enjoy chosen Ubuntu with 45 percent taking the CentOS exam, and only 5 percent opting for the openSUSE test.

    The LFCS and LFCE exams cost $300 each. Certification holders will receive a graphical stamp designating their completion of the exam that can live displayed on resumes, LinkedIn profiles, Web sites and more. If you elect to buy one, I wish you everybitof the luck in the world.

    Q & A with the Authors of "UNIX and Linux System Administration Handbook" | 1Z0-403 true Questions and VCE practice Test

    Evi Nemeth, Ben Whaley, Garth Snyder, and Trent Hein are everybitof experienced sysadmins who bring a profound scholarship of UNIX and Linux to the table. Matthew Helmke recently had the break to inquireof them some questions about their new book, interacting with readers, and whether after 4 editions they admiration themselves sysadmins or authors.

    From the author of 

    UNIX and Linux System Administration Handbook is now in its fourth edition. This classic text is consistently one of the highest rated and most respected books on the topic. In the 20 years since the first edition, the book has continually upped the ante. Already the world's best-selling book on UNIX system administration, it has been improved for this edition with material on several of the leading Linux distributions, such as Ubuntu, RHEL, and OpenSUSE. It is moreover being offered as an eBook for the first time ever.

    I had the haphazard to inquireof the authors a few questions. Ben Whaley, Evi Nemeth, Garth Snyder, and Trent Hein are everybitof experienced sysadmins who bring a profound scholarship of UNIX and Linux to the table, combine it with a covet to participate their scholarship with others who enjoy an interest in the topic, and add to it a bit of wit. The discontinue product is a book that is filled with clearly presented, character information that is enjoyable to read. It turns out they are moreover enjoyable to interview.

    Matthew Helmke: What is your relish with UNIX and Linux system administration?

    Ben Whaley: I started with Red Hat Linux in 1999 while working for very small, family-owned computer repair shop in Wyoming. It was a true tribulation by fire. I bethink that an FTP server I ran was hacked and served pirated software for some unknown length of time. I exchanged email with the author of the exploit (the software was left in unpretentious text on the hacked system) and he said, "Hmm, that works only on poorly configured servers." I learned that lesson the first time, and that's really where my interest in security began.

    At the University of Colorado I had more relish administering Solaris servers in the central UNIX services department. After I left school and started at AppliedTrust, I quickly expanded to larger UNIX and Linux environments. I focused on Red Hat technologies since they remain the leader in enterprise Linux deployments.

    Garth Snyder: My first exposure to system administration came while working for Evi at the University of Colorado during the summers I was in college in the late 1980s. Three of the authors (me, Trent, and Scott Seebass, a coauthor of the first edition) emerged from that milieu. The systems—mostly Sun workstations, Pyramids, and DEC Vaxes running BSD—were incredibly primitive by today's standards, but in many ways it's surprising how petite the major issues of system administration enjoy changed.

    Evi Nemeth: I started with Bell Labs version 6 on a PDP11/45 that I used for teaching computer science at SUNY-Utica. They had no sysadmins, just people enjoy me who liked to tinker and explore. Over the years I migrated from the trenches to supervising student sysadmins and teaching UNIX system administration and networking in the computer science program at the University of Colorado.

    Trent Hein: I started using UNIX in 1984 on Honeywell minicomputer, but really became a system administrator at the University of Colorado in 1987 under Evi's guidance. I've administered Linux systems since the early 1990's.

    Matthew: How did you settle to write this book (or connect the project)?

    Ben: I was fortunate enough to work alongside Trent at Applied Trust. He asked if I'd live interested in working on a few chapters for the 2nd edition of the Linux Administration Handbook, which I gladly accepted. Apparently my contributions weren't too harmful to the book, and the primary author team offered to add me as an author to ULSAH/4E, which I moreover happily agreed to.

    Garth: The original book was everybitof Evi's idea. There was a huge necessity for a book to cover this territory, but nothing was available, so they knew the break was there. They set aside a summer to work complete time on the first edition, and as ludicrous as that seems now, that the book has swelled to almost 1,350 pages, they pretty much completed the initial draft in that time frame. These days, it takes several years to prepare a new edition.

    Evi: In the late 1980s, as I was figuring it out and teaching others, there were no reference materials other than the man pages and UNIX documents. They told you what to do, but not why or when. Visiting publisher representatives, who would often inquireof if I didn't want to write a book, planted the seed, and I recruited two undergraduates who worked with me summers (Garth Snyder from Swarthmore College and Scott Seebass from UC Berkeley) to help. They cranked out a brace of chapters and sent them and the table of contents to three publishers; Prentice Hall accepted us.

    Trent: I appeared on the scene at the University of Colorado around the time that Evi, Garth, and Scott were working on USAH/1E. I was a reviewer for that edition and joined as an author for USAH/2E in 1995.

    Matthew: There are many books on this topic; what distinguishes UNIX and Linux System Administration Handbook from everybitof the rest?

    Ben: I'm a latecomer to the series; my first exposure was using the USAH 3rd edition as the text in a course in school. The string is very well written and highly opinionated. Unlike most desiccate material on the subject, ULSAH makes light of destitute design decisions or confusing aspects of the operating system. No vendor is spared, but Microsoft is ridiculed more than most.

    Garth: Their multiplatform approach is moreover quite unusual, I think—not because they conclude it in a particularly uncanny way, but because relatively few technical books address such a wide variety of systems. Comparisons among systems enjoy been a feature of their book from the very start. ULSAH4E is one of the few resources you can consult to Get a feel for how different it is to manage, say, Ubuntu vs. OpenSolaris systems.

    Evi: In the late 80s, technical books were desiccate and formal and no fun to read. With 2/3 of their team smart undergraduates, they aimed for a tone that would live absorbing to read, disrespectful when things were done wrong by their vendors, and fun. This was furthered when Prentice Hall, a bit worried about new authors, asked for a sample chapter for their copy editors to review and espy how badly they wrote. They sent the finished adduser chapter. The copy editor informed us that company policy was to never exhaust the word "etc.", but to exhaust "and so on" instead. Needless to say, the /"and so on"/passwd file would not fly, and gave us license to ignore copy editors and incorporate an undergraduate tone, making the book both technically amend and fun to read. This tone was enriched by the cartoons at the birth of each chapter, done by a University of Colorado CS undergraduate, Tyler Stevens. They enjoy everybitof new cartoons for this edition, thanks to Lisa Haney, a professional artist.

    Trent: We're professional system administrators, not professional writers. They really conclude this stuff every day.

    Matthew: What has changed in this edition? What new things enjoy you added?

    Ben: Lots of changes in this version! We've added completely new chapters on server virtualization, scripting technologies, and green IT. AIX is now a covered UNIX variant, as well as three Linux distributions. The cover technique and chapter cartoons are everybitof new thanks to Lisa Haney's excellent work.

    Garth: More time and trouble enjoy been dedicated to this edition than to any prior version of the book. In addition to everybitof the new chapters and the new extras (such as the UNIX history section by Peter Salus and a short dialogue with one of their technical commenters, Dan Foster, about AIX), we've expanded the scope of many existing chapters. For example, the discussion of email systems now includes everybitof three of the major platforms: sendmail, Exim, and Postfix. The storage chapter covers technologies such as solid condition arduous drives, Solaris's ZFS filesystem, and the explosive growth of SAN networks.

    Evi: They started this edition as a 20th anniversary edition, expecting it to live published in 2009, and trying to incorporate at least 20 new topics. But alas, they missed their deadline by almost a year; however, 21 is an essential birthday, too, at least in the USA. We've tried to embrace the latest technology and moreover to lose some of their prior Berkeley UNIX biases (e.g., bind and sendmail) with coverage of other competing systems. We've moreover had to admit that Microsoft Windows is here to stay, and they had better embrace it rather than gripe about it; there is a concerted trouble to complicated how to exhaust the best of both Windows and UNIX in a mixed environment.

    Trent: My favorite new addition to this edition is the Green IT chapter. System administrators can reclaim the planet!

    Matthew: What was one of the most surprising things you learned while preparing, writing, and revising this book?

    Ben: I'm not positive that this should live a surprise, but it's clear that modern IT moves more quickly than the writing process. Keeping material current and germane was my biggest challenge. Also, really rooting out the facts of some tangled and unclear protocols and applications (for instance, identity mapping in NFS version 4) is a tough task with everybitof the misinformation on blogs, forums, and the like.

    Garth: Prior to the debut of OpenSolaris, they were seeing the major UNIX vendors gradually cede a lot of ground to Linux distributions in the areas of innovation, configuration management, and common meet and finish. But OpenSolaris and Solaris 11 enjoy surprised and impressed me with their talent to shudder off some of the shackles of the past and to incorporate new and better approaches from the Linux world. It's going to live very absorbing to espy what becomes of these systems now that Oracle is in charge.

    Evi: My biggest surprise, as always, was the huge amount of time it takes to revise a chapter that is only a brace of years out of date. I was happily exploring the San Blas islands of Panama on my sailboat when the muster went out for a 20th anniversary edition. I came home in February, 2009 to work on the book and only flew back a year later on the terminal day my ticket was valid. The other authors picked up the slack in integrating external reviewers' comments and indexing for my chapters.

    Trent: As a system administrator, it's arduous to maintain track of changes in OS versions (and in the industry), such as Oracle's flabbergast renaming of Sun Solaris to Oracle America Solaris. It's even harder as a writer.

    Matthew: conclude readers ever contact you about the book? Why?

    Garth: They do, they do! Usually it's pretty friendly—despite everybitof the inflammatory statements in the book, they don't receive a lot of disapprove mail. The most common request is for answers to the exercise questions at the discontinue of each chapter. Unfortunately, many of those questions (e.g., "Is UNIX doomed?") are designed more to excite thought and provide opportunities for structured analysis than to check for specific factual knowledge. So evaluating someone's answers demands some subjective judgment and familiarity with the subject matter.

    Evi: Yes, in fact a few years ago they had to dump everybitof mail to (our domain denomination for the book) because the spammers instructed recipients to email if they wanted to live removed from the spam mailing list. They typically reply email from users, although as Garth says, it’s often [from readers] requesting answers to the exercises.

    Trent: They hear from readers a lot, actually. Usually they enjoy a chilly legend about how the book helped them, or they enjoy a question about some specific situation. I hope that more than anything they give folks a foundation of scholarship that they can exhaust to decipher any problem, not just the problems specifically covered in the book.

    Matthew: When you read a technical book, what conclude you ogle for?

    Ben: I buy books for accuracy, relevance, and principles. I can find command-line flags and syntax answers via Google. For me, the purpose of a book is to understand higher-level concepts and implementation design. I hope that ULSAH offers a petite of both.

    Garth: A book's intended audience makes a huge difference. I Get the most out of books that assume a technical background similar to mine and that try to buy me to the specific places I want to go. If those factors are a match, I find that many of the other details don't matter so much. Unfortunately, that's a arduous lesson for us to internalize as authors since they know they enjoy readers at many levels of technical skill. They try to flat the playing field by eliminating material that isn't of direct practical capitalize to the majority of readers.

    Evi: I don't read many technical books any more, but in sailing books, the thing I value most is accuracy. Incorrect coordinates on a reef are a total drag! Their review process, first by their coauthors and then by external experts, tends to maintain USLAH pretty accurate. They try to amend any typos or errors that remain in subsequent printings and, of course, list them on their website.

    Trent: Technical accuracy!! It drives me nuts when I find errors.

    Matthew: There are four people listed as coauthors of this edition, but you and I know many more are involved in the process of publishing a book. declare us a petite bit about the collaborative process; both working together as authors as well as working with the people whose names are not on the cover.

    Ben: The author team primarily worked together through Skype conference calls, video conferences, and email. Evi spent much of the writing trouble in Boulder with Trent and me. Garth lives and works in Seattle. During the weighty writing phase, they would spend Tuesday evenings with Garth's face projected on their conference margin wall via Skype while working on their individual chapters.

    We had several contributing authors to manage as well—quality and timeliness were the biggest challenges. Garth is really the project manager/editor extraordinaire behind the writing effort. They each took a few different subtasks to serve push the book forward. For example, I worked with IBM to obtain an AIX sample system. Trent helped us with an HP-UX and Solaris system. The network of industry contacts was moreover immensely useful. I'm very haughty and humbled that Tim O'Reilly wrote the foreword.

    Garth: Every chapter has a primary owner who prepares an initial draft and who shepherds the chapter through a gauntlet of reviews and development. However, each of the primary authors reads and annotates everybitof the material several times, so it's very much a collaborative process, even at the finest flat of granularity.

    Evi: On the collaborative front, their biggest challenge was managing the "ghosties," as they muster them—the people who are better experts in one particular region than they are and who allow themselves to live arm-twisted into writing a chapter or fraction of a chapter. They everybitof enjoy full-time jobs and families; half are better at deadlines than they are, but the other half needed an extra push now and then to Get the chores done. They moreover learned that a conducive sysadmin in a particular region doesn't always besubstantive a conducive writer of the facts for that area.

    Trent: At this point, there's such a community behind this book that it's Amazing how much serve and back they get. They concede dozens of people in the front of the book, and that only scratches the surface. As far as primary authors go, I absolutely loved working with their team on this edition—it's the best group we've ever had. And, for the most part, we're silent speaking to each other!

    Matthew: When you deem about yourself, conclude you admiration yourself primarily a writer or a sysadmin? Why?

    Ben: absorbing question. I deem of myself as a technical sysadmin with a penchant for writing. A solid background in writing is terribly useful as a technical person, of course. Being able to communicate technical concepts clearly is a rare skill in IT, and one that I continue to hone in my career.

    Garth: I esteem software and software systems generally. At this point, I've spent more time as a software developer than as a system administrator, but to declare the truth, I don't espy much dissimilarity between the two. System administration has many of the identical rewards and challenges as, say, web development.

    Evi: Since retiring from the Computer Science faculty at the University of Colorado, I've been more of a sailor than either a sysadmin or a writer. But I've probably spent more time writing than fighting with the administration of my laptop.

    Trent: I'm a system administrator. That's my day job. Writing is just a way of sharing that.

    Matthew: conclude you enjoy any counsel for people who want to become sysadmins or writers?

    Ben: For sysadmins, I'd jabber the most essential thing is to Get your hands dirty. Practice, practice, practice. I was lucky enough to start at a very immature age (14) and quickly logged a great number of hours doing work on the computer. scholarship is easily transferable, so lessons learned on one system/application/environment are very portable to other areas.

    Garth: If you can deem logically, you can learn to write. For someone that wants to write about technical subjects, I'd suggest putting the accent on the subject matter rather than on writing per se. An entire editorial industry is devoted to fixing up people's imperfect English. However, relatively few people can catch technical errors in your flawlessly written prose.

    Evi: conclude it. You don't really understand something unless you enjoy to conclude it or instruct it. Sysadmins can grab any number of open-source operating systems, install them on commodity hardware, and play away. Volunteering to serve out often opens doors in student labs. Try your hand at writing things enjoy a lab manual for your school computing lab.

    If software is your strength, volunteer for one of the open source projects. You can't just jabber I'm Joe/Jane Undergrad and I want to work on the Linux kernel, too; but you can start contributing patches to software bugs you find or tools that you enjoy written. Reading the mailing lists of open-source projects can acquaint you with the community.

    Trent: The world needs more sysadmins—I deem everyone who's detail-oriented, a conducive problem solver, and likes multitasking should admiration it as a career. As I declare everybitof the folks I work with, this is one job where you are NEVER bored.

    Matthew: Thank you everybitof for your time and absorbing responses.
