What to know
- CompTIA Linux+ exam objectives (certification page): RoleMath records this against exam XK0-006 and has not verified whether that is still the current exam — check the vendor's page before relying on it. Official CompTIA certification page with current Linux+ exam-objective context. (noted when we read this source, 2026-07-01)
- CompTIA Linux+ practice questions (official, free): Ten questions. Enough to calibrate format, nowhere near enough to measure readiness. (noted when we read this source, 2026-06-29)
- Linux Foundation: Introduction to Linux (LFS101) — free: Distribution-general rather than written to the CompTIA Linux+ objectives and it stops short of the exam's depth on scripting; automation; and troubleshooting. The 90-day access window starts at enrolment — begin it when you intend to study rather than to bookmark it. (noted when we read this source, 2026-07-30)
The free path, in order
1. Start from the exam objectives / outline — it is the scope the certifying body itself publishes, and where a vendor also publishes domain weightings they are in it. It may not be a comprehensive list of every exam topic. Study against it, not against a course's table of contents. Where the entry below records an exam version RoleMath has not verified as current, confirm on the vendor's page that you are reading the outline for your exam before you study against it.
2. Free course material is listed above, but RoleMath does not count it toward a complete free path — our last check did not confirm that any of it is current for this exam version, reachable without an account, and inside our re-verification window. Use it for instruction where it helps, and treat the exam objectives as the authority on scope.
3. Free study lowers what you spend preparing, not what the exam itself costs — see what it costs to earn and keep.
Free resources reduce what you spend to study. No resource guarantees a pass, and a course is not the certification.
