Scoring method: Scaled scoring on a 100–900 scale. Passing score is 720. Performance-based questions are weighted more heavily than standard MCQs and increased in emphasis relative to XK0-005. No negative marking.. The exam may include unscored pilot questions - treat every question seriously.
Focus Areas

What should you study for the CompTIA Linux+ exam?

To pass the CompTIA Linux+ certification exam, you should focus on these core domains. The exam tests your ability to apply concepts in real-world scenarios - not just memorise definitions.

⚠️
Common mistake: Candidates memorise terminology but struggle with scenario-based questions. Focus on when to use what, not just what exists.
🔐
System Management (23%)
Narrower than in the retired XK0-005 (was 32%) — user/service management was split out into its own domain. Covers boot process, storage, networking, and virtualization.
🏗
Services and User Management (20%)
New standalone domain in XK0-006 — was folded into System Management under XK0-005. Covers permissions, users/groups, processes, package management, and system services.
⚡
Security (18%)
Slightly narrower than XK0-005's 21% — covers authentication, access control, and hardening.
💰
Automation, Orchestration, and Scripting (17%)
Renamed and refocused from XK0-005's 'Scripting, Containers, and Automation' (19%) — container coverage moved to Services and User Management; this domain now emphasizes Python, Git, CI/CD, IaC, and AI-assisted development practices.
🔄
Troubleshooting (22%)
Slightly narrower than XK0-005's 28% — covers systematic diagnosis across hardware, storage, network, and application/security issues.

Tips to pass CompTIA Linux+ on your first attempt

Tactical advice beyond content knowledge - what separates candidates who pass from those who retake.

🗓
XK0-005 retired January 13, 2026 — if your study material still shows 4 domains with System Management at 32%, it's for the retired exam. XK0-006 has 5 domains.
🔍
System Management (23%) and Troubleshooting (22%) together are still nearly half the exam, but System Management is now narrower — Services and User Management (20%) was split out as its own domain.
⏭
Build a hands-on Linux lab using VirtualBox or a cloud VM — Linux+ heavily tests practical skills via performance-based questions, and PBQ weight increased in XK0-006.
📊
Basic Python scripting is newly emphasized alongside Bash — don't assume shell scripting alone covers the Automation domain.
🔁
AI-assisted development (code generation best practices, prompt engineering) is brand-new content in XK0-006 — not covered on the old XK0-005.
🧪
Practice the complete boot process: BIOS/UEFI → GRUB → kernel → initrd → systemd.
📝
Master LVM commands: pvcreate, vgcreate, lvcreate, lvextend, and resizing filesystems.
🎯
Learn SELinux contexts and common troubleshooting: use getenforce, setenforce, restorecon, and audit2allow.
🗓
Understand both APT/dpkg (Debian/Ubuntu) and YUM/DNF/RPM (RHEL/CentOS) package management — now grouped under Services and User Management.
🔍
Use CompTIA's official CertMaster Learn or Practice tools, and simulate PBQs in a live Linux environment.

⚠️
Avoid brain dumps. Sites selling "real exam questions" violate most vendor NDAs and are legally risky. Questions rotate regularly - brain dumps lead to overconfidence on outdated material and a higher retake rate.
