CompTIA Linux+ Certification:
Training, Practice Tests, and Exam Vouchers
CompTIA Linux+ is a certification that proves you can configure, manage, secure and troubleshoot Linux servers, the systems that run most of the cloud, the web and the enterprise data center. It’s built for IT professionals with about a year of hands-on Linux experience who want to show they can handle real administration work, from storage and services to scripting, containers and automation.
The current exam is XK0-006. Total Seminars sells the official voucher for $356.99, 11% below the $399 retail price, plus the video training and practice tests that get you ready to certify.

What the CompTIA Linux+ exam covers
CompTIA Linux+ (XK0-006) proves you can run Linux servers in a modern IT environment. The exam spans five domains:
- System management (23%): Understand the boot process and filesystem hierarchy, manage devices and storage with LVM and RAID, configure networking, work in the shell, back up and restore servers, and run virtual machines with KVM.
- Services and user management (20%): Manage files, accounts, processes and jobs, install and configure software, control services with systemd, and run applications in containers with Docker and Podman.
- Security (18%): Configure firewalls, harden the operating system and user accounts, apply SELinux and access controls, secure remote access, use encryption and follow compliance and audit procedures.
- Automation, orchestration and scripting (17%): Automate with Ansible, Puppet and OpenTofu, orchestrate with Kubernetes, write shell scripts, use Python for administration, manage code with Git and apply AI responsibly.
- Troubleshooting (22%): Monitor systems and diagnose hardware, storage, OS, networking, security and performance problems.
Where to focus: System Management and Troubleshooting together make up 45% of the exam. Hands-on time at the command line pays off in both.
Exam Format, Scoring and Career Path
Question format: You get up to 90 questions and 90 minutes, so about a minute per question. Most are multiple choice, but Linux+ also uses performance-based questions that put you at a command line or in a scenario and ask you to complete a task, not just describe it.
How the exam is scored: Two things are worth knowing before test day:
- Wrong answers don’t count against you. CompTIA doesn’t take away points for incorrect answers, so answer every question, even if you aren’t sure.
- The score is scaled. Results are reported on a scale of 100–900, and you need 720 to pass. Performance-based questions take longer, so flag them, work through the quick wins and come back.
Where Linux+ Can Take You
Linux runs most of the world’s servers, cloud platforms and containers, so Linux skills open doors across IT. Linux+ is vendor-neutral and covers the major distribution families, so what you learn applies whether your organization runs Red Hat, Ubuntu, Debian or SUSE.
It’s a strong fit for Linux and systems administrators, cloud support engineers, junior DevOps engineers and site reliability engineers. With automation, containers and scripting built into the exam, it also prepares you for the infrastructure-as-code work modern teams depend on.

Is Linux+ right for you?
Who the Linux+ exam was written for, and how your background shapes the challenge.
Linux+ sits on CompTIA’s infrastructure path alongside Server+ and Cloud+, and it’s built for the people who manage the machines everything else runs on.
CompTIA recommends about a year of hands-on Linux server experience before you sit the exam. Recommends, but does not require. People with less experience do pass. But that recommendation tells you who the exam was written for, and it’s the best predictor of how hard Linux+ will feel to you.
How your background shapes the challenge
If you already administer Linux, most of the exam will feel familiar. Your work is filling gaps in areas you don’t touch every day, such as Kubernetes, Python or SELinux.
If you come from Windows administration or help desk, the concepts will make sense, but the command line won’t be automatic yet. Plan extra time for hands-on practice.
If you’re new to IT, Linux+ is a big step. Build a foundation with A+ and Network+ first, or plan a longer study timeline with plenty of lab work.
Short on experience? Build it while you study
Linux is free. Install a distribution in a virtual machine or spin one up in the cloud, and practice each objective as you learn it. Use one RPM-based and one Debian-based distribution, such as Rocky Linux and Ubuntu, to cover both sides of the exam. A few months of daily practice can close much of the gap the recommendation describes.
How Hard Is the CompTIA Linux+ Exam?
Linux+ tests whether you can run a Linux server, not just name the commands. Here are the three things that make it hard and how to know you're ready.
Linux+ is written for someone with about a year of hands-on time on Linux servers, and it tests whether you can run a Linux system, not just recognize the commands. That’s what makes it tougher than it looks. It’s also what makes it worth having.
But “tough” doesn’t mean “out of reach.” The objectives are fully published, the passing score leaves room for mistakes, and every skill it tests can be learned with the right kind of practice.
The three things that make it hard
1. You have to know the command, not just the concept. Performance-based questions ask you to complete a task. Knowing that LVM exists won’t help if you can’t remember whether you need lvextend or vgextend.
2. The range is wide. In one sitting you might configure a firewall, read a systemd unit, troubleshoot a full filesystem, fix a Bash script and answer questions about Kubernetes. Almost everyone has gaps to fill.
3. Linux isn’t just one system. The exam covers both sides of common splits: RPM vs. dpkg, firewalld vs. ufw, NetworkManager vs. Netplan. If you’ve only used one distribution, the other side can catch you off guard.
How to know you’re ready
- You can perform common tasks from memory on a real Linux system, such as managing users, mounting storage, setting permissions and restarting services.
- You can explain why an answer is right, not just recognize it.
- You pass timed practice exams comfortably across several attempts, not just barely once.
The video course and TotalTester practice tests above are built to get you there.
