What is LPIC-1 Certification?
Saturday, 23 October 2021
The People Behind the Learning Portal: Marco Colombo, Learning Materials Author and Translator
With this post, we get acquainted with Marco Colombo, an LPI certified professional who started his journey of developing LPI-related learning books years ago and is now part of the Learning Portal Team.
Marco, what is your academic and professional background?
I have a degree in Telecommunications Engineering, and I am currently working as a network administrator in an organization operating in higher education. I have always been a lover of technology and Linux, and I love to stay up to date, especially in the open source field. I do believe that in life you never stop learning and that you must always give the best of yourself, loving what you do.
When and how did you decide to use your skill in developing learning materials?
Immediately after earning the LPIC-1 certification.
The idea of collaborating with LPI in writing completely free educational material was undoubtedly a great way to put into practice what I learned during my certification journey, while allowing me to further hone my Linux skills. It's "Learn by Doing", quite literally!
While on my LPIC-1 certification journey, I started creating a series of exercises that could help me learn Linux. I decided to redesign the exercises into a series of questions and answers, perfectly matching the actual LPI exams. All that work became two, let’s call them "simulation books" for the 101-500 and 102-500 LPI exams. The books had quite a great success.
My vision behind them was to create educational material that could help anyone become an LPIC-1 certified professional. Each book consists of 250 questions and answers divided into 4 practice exams—simulating the actual exam—and 1 assessment test.
All the questions are explained step by step, so the reader can fully understand the general background to which each question refers. Now the books LPIC-1 101-500 Practice Exams and LPIC-1 102-500 Practice Exams are part of the official LPI Learning Materials too: Thank you, LPI!
What is your contribution, so far, to the Learning Portal, and what's next for you in this project?
Working on the Learning Portal, I have designed lessons for the Linux Essentials, LPIC-1, BSD Specialist, and Web Development certifications.
In the future, I would also like to contribute to the translation of the Learning Materials into Italian. The LPI Learning Portal is indeed a fascinating and engaging project.
Being a certified professional and a learning material writer makes you aware of the two sides of the coin: From this particular point of view, what is your advice to people studying for their LPI Exams?
My advice is: “practice, practice, practice!”Of course you need to know, but you must make skills out of that knowledge: hence, you need to practice a lot. Because once you earn your Certification, you will have to face the actual work environment, and you need to be ready for it. Just stuffing in concepts is entirely useless, so: practice, practice, practice!
And how do you advise teachers and, more broadly, people involved in the use and even the production of Linux and open source learning material?
As I said, the LPI Learning Portal is an exciting project: I take this opportunity to invite teachers and Linux and lovers of open source to come forward and collaborate in the drafting of educational material that can help others. If each of us makes our knowledge available, the community will benefit a lot, in addition to empowering the community's individuals.
The LPI Learning Portal is a community, as you say: what is your experience so far, what tools and features do you use in the process? What can you tell us about the workflow? And what "opensourceness" can you recognize in a project about education?
The experience within the community is just brilliant. Each person who decides to collaborate is entrusted with a specific activity based on abilities and availability. The drafting, verification, and translation activities are expertly coordinated by professionals who are always ready to provide their invaluable help if needed.

LPIC 1 vs Linux+: Where to Start
If you're ready to set down the path of Linux specialization, there are several key certifications that will help you. While some exams are tailored to vendor-specific distributions, Red Hat certifications being the most notable, there are two that stand out in the vendor-neutral, entry-level space: CompTIA Linux+ and Linux Professional Institute (LPI) LPIC-1.
Until April 2019, CompTIA and the LPI had a partnership that guaranteed LPIC-1 certification to anyone who passed CompTIA's Linux+ exam. CompTIA's reasoning and the LPI's explanation diverge on a few details of their breakup, but that's not entirely the point here.
Here's what matters: which certification should you pursue? Is Linux+ or LPIC-1 right for you?
A Look at Linux+: A Breakdown
According to CompTIA, it's new Linux+ certification exam targets IT pros who use or will use Linux to manage everything from cars and smartphones to servers and supercomputers. It also will help candidates who work in enterprise environments that use Linux. The biggest change from the previous Linux+ exam is that it covers security in-depth, alongside new topics like kernel modules, cloud management, and DevOps.
If you're in the early stages of your system admin career and want to establish a solid groundwork for working in Linux environments, Linux+ is a great option. The fact that it's distro-neutral means that it's applicable to any Linux system, which will make you a valuable asset to wider range of organizations.
CompTIA is a well-known name in the IT certification industry. Their certifications certainly add a great deal of weight to a professional resume, especially in the United States, where their vendor-neutral certifications are easily recognizable. For U.S.-based IT professionals, especially those interested in working for organizations such as the Department of Defense, Linux+ offers attractive credibility. CompTIA certifications are DoD-approved.
Linux+ certification is also a great option for professionals who want to continue further down the CompTIA certification path, for example with cybersecurity certs like CySA+ and CASP+.
However, Linux+ does have its drawbacks. It's generally considered one of the easier IT certification exams, and many professionals believe that it doesn't carry the same weight as more prestigious certifications. Others claim that these faults result in an exam that doesn't indicate whether or not a professional is up to the task of Linux administration.
A Look at LPIC-1: The Breakdown
The LPIC-1 is the first certification in the Linux Professional Institute's multi-level Linux certification program. The LPIC-1 validates "the candidate's ability to perform maintenance tasks on the command line, install and configure a computer running Linux and configure basic networking."Because the LPIC-1 certification requires two exams, it's generally regarded as more difficult than the CompTIA exam, as it casts a wider net and contains more extensive questions.
The LPIC-1 was released in 1999, making it the oldest available vendor-neutral Linux certification. The LPI is a non-profit organization that embodies Linux's open-source ethos. There are 175,000 certificate holders across over 180 countries, so this organization has unparalleled clout on a global scale. Put together, this makes the LPIC one of the world's most recognized certifications for Linux professionals, especially among the IT community itself.
LPIC-1 is also distro-neutral and ideal for IT professionals interested in pursuing positions such as system administrator, network administrator, and system engineer. Because the LPI embodies the community-driven nature of open-source software, this alignment makes LPIC-1 certification an even more attractive option.
Linux+ vs LPIC1: Which Should You Earn?
First, in a vacuum, we recommend the LPIC-1. We believe that LPI's position as a globally recognized body of Linux experts who strive to uphold the technology's foundational principles sets it apart from the competition. No matter where you are or what type of Linux environment you'll be working in, LPIC-1 certification will always be useful and relevant.
Secondly, what are your career goals and desired trajectory? If you're a devoted Linux fan who wants to climb the LPIC ladder toward LPIC-3, then you'll want to start with LPIC-1. Another reason in LPIC-1's favor is if you're applying to positions outside the U.S. or want to work in IT, the hiring manager is more likely to have a tech background and therefore value LPI certifications.
If you're a U.S. professional, want to pursue a career that doesn't focus so heavily on Linux administration, or applying with an organization that isn't as IT-centric, then Linux+ may be a better option. In this case, the CompTIA certification will be more recognizable and provide a better pathway.
Final Thoughts
Linux is found in nearly every server room these days. Long gone are the days of it being a fad or an OS for hobbyists. In fact, many enterprises are now using Linux in some form or another. Even Microsoft has embraced Linux after years of dismissing open source technologies.
As a result, the demand for IT pros with Linux skills has increased rapidly in recent years. The best way to start building a Linux foundation is through certification — and you can't go wrong with LPIC-1 or Linux+. Start adding Linux to your IT skill set today.

LPIC-1 exams available online in Spanish
In 2020, Linux Professional Institute (LPI) started offering its certification exams online. Since then, the exam development team has been working hard to offer these online exams in different languages as well. In addition to English and Japanese, the LPIC-1 exams are now available online in Spanish.
For some time, candidates for Linux certification have been able to take the first-level exams, LPIC-1, in Spanish. But to do so, candidates needed to travel to test centers or other places where exams are held. This is difficult for people outside major urban centers, and dangerous in many regions following the spread of the COVID-19 virus. Today LPI announces the availability of LPIC-1 exams in Spanish online from a home, workplace, or college, through the Pearson VUE OnVUE testing system.
The mission of LPI is to promote the use of open source by supporting the people who work with it. As part of this mission, it has expanded test-taking in two important ways: by translating exams and Learning Materials into more and more languages, and by offering them online to give more and more people around the world the chance to take them.

LPIC-1 101 Learning Materials released in Spanish and Portuguese
The LPIC-1 Learning Materials for the 101 exam are now available in Spanish and Portuguese. This comprehensive guide is part of a series of Learning Materials developed by Linux Professional Institute (LPI) volunteers around the world to alert candidates to the topics they will encounter on the LPI exams. The Learning Materials are not meant to be a substitute for the other sources of information: training programs, books that are available through many publishers, and--of course--intensive, hands-on experience with the computer systems themselves.
Also Read: 101-500: Linux Administrator - 101 (LPIC-1 101)
LPI is committed to providing access to knowledge about free and open source software to as wide a range of users and administrators as possible. As part of that goal, LPI has been translating both its tests and its training materials into a number of languages.A growing number of the exams is available online in Spanish and Portuguese, using the Pearson OnVUE service. Where pandemic conditions allow people to gather in person, the LPIC-1 exams are also available in these languages.
"With the translation of the Learning Materials for the first LPIC-1 exam into Spanish and Portuguese, we have reached another important milestone," says Dr. Markus Wirtz, Manager Education Programs LPI. "My special thanks go to the translators and reviewers for their great work."
Further translation efforts are underway, and will be reported on lpi.org
