The New CompTIA Linux+: Your Questions Answered

by Kristin Ludwig | Apr 03, 2019

From emerging tech and the cloud to cybersecurity and DevOps, Linux is everywhere and used to manage everything from cars and smartphones to servers and supercomputers. This week, CompTIA launched the latest version of CompTIA Linux+ (XK0-004), which was revised in many ways beyond the obvious change from two exams to one. The new CompTIA Linux+ validates the skills you need to use Linux in today’s tech environment in jobs such as systems administrator, network administrator, web administrator, Linux software developers and more.

We know you have questions about the new exam, so we’ve asked Zach Hill from I.T. Career Questions to help you understand what’s on the new exam and how it will help you in your IT career.

What’s on the new CompTIA Linux+ exam?

The new CompTIA Linux+ validates the competencies required of an early career IT professional supporting Linux systems.

In addition to topics traditionally associated with systems administration tasks, such as configuring, managing, operating and troubleshooting in a Linux environment, the new exam has an increased focus on the following areas:

  • Security
  • Kernel Modules
  • Storage and virtualization
  • Enterprise-level device management
  • DevOps basics, through Git and automation
  • Networking and firewalls, especially involving security issues
  • Server side and command line, for server management in a multi-server environment
  • Troubleshooting
  • SELinux, with a focus on implementation of this robust security system

Why would I choose to take CompTIA Linux+ instead of other Linux certifications?

CompTIA Linux+ is the only job-focused Linux certification covering the latest foundational skills demanded by hiring managers. Unlike other certifications, the new exam includes performance-based and multiple-choice questions to identify the employees who can do the job.

The exam covers tasks associated with all major distributions of Linux, setting the foundation for advanced vendor/distro-specific knowledge.

How much time will I need to prepare for CompTIA Linux+?

Can I still take the CompTIA Linux+ LX0-103/104?

Yes, the CompTIA Linux+ (LX0-103/104) will be available until October 1, 2019.  Proof of successful completion of CompTIA Linux+ (LX0-103/104) can also be submitted to LPI for LPIC-1 certification (not available with CompTIA Linux+ (XK0-104)).

I already passed CompTIA Linux+ LX0-103, but I haven’t taken LX0-104 yet. What should I do?

To earn your CompTIA Linux+ certification, you need to successfully complete either LX0-103 and 104 or XK0-004. So, if you’ve already passed LX0-103, continue preparing for and take LX0-104. Just make sure you take your exam before it expires on October 1, 2019.

I’ve been studying for CompTIA Linux+ (LX0-103/104). Should I switch gears and study for CompTIA Linux+ (XK0-004) instead?

If you’ve been studying for the CompTIA Linux+ (LX0-103/104), we would recommend reviewing the exam objectives to see how much of what you’ve already studied is on the new exam. If it makes sense for your time and level of knowledge, you may want to switch gears and prepare for the new exam (XK0-004). 

Some of the benefits of taking the new CompTIA Linux+ is that it covers the latest subject matter and it costs less, since you’ll take just one exam instead of two.

Keep in mind that if you choose to pursue LX0-103/104, you must take both exams by October 1, 2019, in order to get your CompTIA Linux+ certification.

    In the original Sneak Peak and the Partner Webinar back in September of last year, you all stated that the Linux+ was not going to be part of the CE Program. However, results of the Beta exams have came out, as well as what we are seeing on the Linux+ page, makes it seems like the this decision was changed. Can we get some clarification on this. We haven't seen any official annoucement and even this page doesn't mention that it's going to be part of the CE Program.

    Linux is also the foundation for most Cloud Native Container applications. As an example, Kubernetes is an open-source container orchestration system for automating application deployment, scaling, and management. It was originally designed by Google, and is now maintained by the Cloud Native Computing Foundation.

    Will the LPIC-1 path be removed from CompTIAs exams entirely when the old 2 part exam is retired?

  • Monday, April 8, 2019

    Hi, Adam! Thanks for your question. The new CompTIA Linux+ is not reciprocal with LPIC-1.

    If I get certified under the two-part exam before it retires, will that still be lifetime?

  • Thursday, April 11, 2019

    Hi, Billy! Yes, if you take 103/104, it is good for life.

    Where in the line up on the certification branch/tree will Linux+ be? After Security+, on the Cyber security line/branch or by itself like project management?

    Am I understanding that this new one will no longer be a for life certification?

  • Daniel Miller

    Friday, April 12, 2019

    Where can I find study material for the XK0-004 Linux +?

  • Friday, April 12, 2019

    Hi, Sharon! Thanks for your question. Although Linux certainly applies to cybersecurity, CompTIA Linux+ is in the CompTIA Infrastructure Career Pathway. While the certifications in the CompTIA Cybersecurity Career Pathway tend to build upon each other, the certifications in our infrastructure pathway tend to be more parallel. There is no set order in which to take them - choose the ones that make the most sense for your career path. That said, we recommend taking the core certifications (CompTIA A+, CompTIA Network+ and CompTIA Security+) before embarking on either pathway and waiting to get certified until you have the recommended level of experience. Good luck!

  • Friday, April 12, 2019

    Hi, Travis! Thanks for your question. You are correct - the new Linux+ is a CE exam, which means you need to renew it every three years to keep it active. Good luck!

  • Friday, April 12, 2019

    Hi, Daniel! Thanks for your question. First, you can download the exam objectives and practice questions from this website. When you're ready to take your training to the next level, check out the CompTIA Store for the Official Study Guide for CompTIA Linux+ (print or eBook) as well as a full line of CertMaster eLearning products that cover learning, hands-on practice and exam prep. Good luck!

    Hello! I do not find the material to study for the new certification XK0-004 in the website Where can I find books and material? Many thanks! Matteo

  • Tuesday, April 30, 2019

    Hi, Matteo! Thanks for your questions. If you are looking for the exam objectives and practice tests, navigate to Training > Practice Test or Exam Objectives. After you complete the download form, scroll to the bottom of the list to get the objectives for CompTIA Linux+ XK0-004. If you are interested in purchasing training material, like the official study guide or CertMaster products, go to and navigate to Training > Linux+. There you'll find products for both versions of Linux+. Good luck!

    I earned Linux+ in 2013. Can I have that certification converted to the new CE certification?

  • Monday, May 13, 2019

    Hi, Nick! Thanks for your question. The Linux+ you earned in 2013 is good for life, which means it won't expire. If you would like to obtain the CE version, you'll need to take and pass the new exam - you may not convert your good for life cert to CE. Good luck!

  • David

    Monday, June 10, 2019

    Will CompTIA allow Linux+ good for life cert holders to sign up for CE in order to obtain the new Linux+, similar to what they did with Security+ good for life cert holders?

  • Monday, June 10, 2019

    Hi, David! Thanks for your question. Due to the major subject matter enhancements to Linux+, we are unable to offer the same option we did for Security+.

  • Iris

    Friday, June 28, 2019

    Will getting the new Linux+ exam extend A+, Network+, and Security+ expiration dates if we have them? Will the old Linux+ exams extend them?

  • Monday, July 1, 2019

    Hi, Iris! Thanks for your question. All available versions of Linux+ will renew CompTIA A+. Getting Linux+ would not renew any other CompTIA certifications. You can learn more about higher-level CompTIA certs here: Good luck!

    Does the new XK0-004 certification need to be renewed every 3 years or is it good for life?

  • Friday, August 2, 2019

    Hi, Peter! Thanks for your question. Yes, Linux+ XK0-004 is a CE certification, which means you need to renew it through continuing education activities every three years.

  • Bryan Hernandez

    Wednesday, August 7, 2019

    What happens if I cannot take the second test after it's end of life?

  • Wednesday, August 7, 2019

    Hi, Bryan! Thanks for your question. In order to earn Linux+ by passing LX0-103/104, you would need to pass both exams by October 1, 2019. If you do not, you would need to take XK0-004 to earn Linux+. The old exams will no longer be available after the retirement date. Good luck!

  • Ryan

    Sunday, August 18, 2019

    So I just want to clarify something here... I don't have Linux+ yet. If I take the old 2 exams before the October end of life, I will have Linux+ certification for life without having to renew it. But if I wait and take the newer (arguably better) exam, I will have to renew it periodically, right? So I should probably hurry and take the old ones to have Linux+ for life right?

  • Tuesday, August 20, 2019

    Hi, Ryan! Thanks for your question. That is truly a personal decision, and you have to weigh your options to see what makes the most sense for you. Employers who look for CompTIA certifications know the difference between good for life and CE, and they may be looking for someone who is keeping their skills up to date by taking the newest version of the exam and keeping up on continuing education. The old exam also costs more since you are paying for two vouchers. And, if you choose to get higher-level certifications later on (CompTIA or otherwise), those could automatically renew your Linux+. You also have to decide if you can successfully speed through the process to study for and pass two exams in two months. If you attempt the old version and aren't able to pass both exams in time, you will have to buy another voucher to take the new one anyway. Good luck!
