Expert take: what CompTIA Linux+ really tests
CompTIA Linux+ is a vendor-neutral, hands-on Linux exam, and the current version (XK0-006, launched mid-2025) modernised it heavily — adding automation with Ansible, version control with Git, basic Python and even AI-assisted workflows alongside the classic command-line administration. Its performance-based questions mean you cannot bluff it from slides; time on a real Linux system is what carries you over the 720 bar.
Preparation tips
- Study the current XK0-006 objectives — automation, Git and scripting are now in scope.
- Practise on a real Linux system for the performance-based questions.
- Learn commands with their options and syntax, not just their names.
Common mistakes to avoid
- Preparing from older XK0-005 material and missing the new automation and scripting content.
- Studying theory without doing real command-line and troubleshooting tasks.
