Preparing for CompTIA Linux+ V8 (XK0-006)? This is the current Linux+ exam: it launched on 15 July 2025 and replaced XK0-005. It covers system management, services and users, security, automation and scripting (now including Python, Git and responsible AI use) and a large troubleshooting domain. These tests show you which objectives you already own and which ones still need work.

You get four tests with 50 questions each - 200 in total, written from CompTIA's official Linux+ XK0-006 exam objectives (document version 5.0). Every question is tied to one objective, so when you get one wrong you know exactly what to revise.

What makes the explanations useful

Each answer tells you why the right option is right and why each wrong option is wrong. The wrong options are where most of the learning is: they are real features, commands and settings that are easy to pick by mistake.

How the tests are built

• Test 1 - System management: domain 1.0: boot process and FHS, device management and kernel modules, storage with LVM and RAID, network configuration, shell operations, backup and restore, and virtualization.
• Test 2 - Services, user management and security: domains 2.0 and 3.0: files and permissions, local accounts, processes and jobs, software and repositories, systemd, containers, PAM/LDAP/Kerberos, firewalls, OS and account hardening, cryptography and compliance.
• Test 3 - Automation, scripting and troubleshooting: domains 4.0 and 5.0: Ansible and other automation tools, shell scripting, Python basics, Git, responsible AI use, monitoring, and troubleshooting hardware, storage, networking, security and performance.
• Test 4 - Full mock exam: 50 mixed questions across all five domains, weighted like the real exam, with a time limit.

Questions use single-answer and "choose two" formats; "choose two" is always stated in the question. Suggested time: 75 minutes for Tests 1-3, 90 minutes for the mock.

Versions: current mainstream distributions (RHEL 9/10 family, Debian, Ubuntu) with systemd, nftables/firewalld/UFW, Podman and Docker, Ansible, Git and Python 3. The answers were checked against official documentation in October 2026.
