ExploreAbout this exam
CompTIA Linux+ (V8) is a vendor-neutral certification, exam series XK0-006, that validates the ability to manage, secure, automate, and troubleshoot Linux systems in cloud and hybrid environments. It launched on July 15, 2025, and is aimed at practitioners who already have roughly 12 months of hands-on experience with Linux servers; CompTIA A+, Network+, or Server+ (or comparable knowledge) is recommended before you start. The credential is positioned for roles such as Linux systems administrator, systems engineer, and network engineer - people who support and protect the Linux platforms businesses depend on.
The exam is delivered in English, contains a maximum of 90 questions mixing multiple-choice and performance-based items, and runs 90 minutes, with a passing score of 720 on a scale of 100–900. Objectives are weighted as System Management (23%), Services and User Management (20%), Security (18%), Automation, Orchestration, and Scripting (17%), and Troubleshooting (22%). Content spans boot and storage management, networking, permissions and accounts, process and software management, containers and virtualization, firewalls and hardening, shell scripting, Python, Git, configuration management, and systematic fault diagnosis.
Preparation typically combines structured instruction with hands-on lab work on real or simulated Linux hosts. CompTIA markets CertMaster Perform, Learn, Practice, and Labs, and bundles vouchers with Retake Assurance.
What you'll study
About CompTIA Linux+ preparation
How many questions are on the Linux+ V8 exam and how long do I have?
A maximum of 90 questions in 90 minutes. The item mix is multiple-choice and performance-based, so budget time carefully: performance-based tasks can consume far more minutes than a single multiple-choice question. Practice pacing yourself on hands-on tasks before exam day.
What score do I need to pass?
720 on a scale of 100–900. Because the scale is not a raw percentage, you cannot convert it directly to "questions correct." Aim to be comfortably consistent across all five domains rather than maximizing one area, since every domain carries meaningful weight.
What is the exam code and version?
The exam series code is XK0-006 and the version is V8, launched July 15, 2025. Use the code when registering and when checking that any study material you buy maps to V8 objectives - older editions cover different content and weighting.
In what languages is the exam offered?
English. CompTIA lists English as the available language for this exam. If English is not your first language, factor extra preparation time into reading long scenario-based and performance-based prompts under a 90-minute limit.
Do I need experience before taking it?
CompTIA recommends 12 months of hands-on experience with Linux servers, plus CompTIA A+, Network+, or Server+, or comparable knowledge. In practice, candidates with no command-line comfort struggle most with the performance-based items, which require real configuration rather than recall.
How long is the certification valid?
CompTIA states the exam is usually retired about three years after launch, estimated 2028 for V8. Specific continuing-education and renewal requirements are not detailed in the source material, so confirm current recertification policy with CompTIA before you plan your renewal cycle.
Is there a retake if I fail?
CompTIA's Linux+ bundles pair a voucher with Retake Assurance, which provides a built-in exam retake for peace of mind. A standalone retake policy and its pricing or waiting period are not published in the source material, so verify the current terms at purchase time.
What should I study first?
Follow the weights: System Management (23%) and Troubleshooting (22%) are the largest, then Services and User Management (20%), Security (18%), and Automation, Orchestration, and Scripting (17%). Build a working Linux lab early so storage, networking, containers, and scripting objectives become practice rather than memorization.
How much study time should I plan for?
CompTIA's own product tiers estimate roughly 30–60 hours for the full Perform package, 25–40 hours for Learn, 10–20 for Practice, and 15–25 for Labs. Treat those as guided-content estimates; candidates starting below the recommended experience usually need considerably more lab time.
Where do candidates lose the most points?
The usual weak spots are hands-on troubleshooting (boot, mount, DNS, firewall, SELinux) and scripting, because both require producing correct commands rather than recognizing them. Reading only, without typing configurations on a real host, is the most common preparation mistake.
