LPI certifications

LPIC-1 takes two exams, 101 and 102, each ninety minutes and sixty questions, each passed at 500 on LPI's scale of 200 to 800, with no prerequisite and six exam languages. Hiring managers rarely ask for it by name, because Linux ability is checkable at a keyboard in twenty minutes; the certificate's value lies in its objectives. They map what a competent administrator should know, and few self-taught administrators have covered all of it: the boot chain that never failed, the packaging tools of the distribution family they avoid, the regular expressions they route around with three greps in a pipe. Working through 101 and 102 finds those gaps as further tinkering will not. The exams suit the self-taught administrator with patchy coverage, the career changer with no job title to point at, and anyone who wants to be examined in German. They add little for someone who runs systems all day and can show the fleet and a colleague who vouches for it; that record outweighs an associate certificate.

Five years, and three ways to extend them

One sitting covers a whole stretch of a career, and LPI offers three routes to keep the certificate current. The holder can retake whichever 101 and 102 are current, paying twice for a syllabus that has moved on. The holder can pass LPIC-2, which renews LPIC-1 with it; an LPIC-3 specialty later renews both. Or the holder can join LPI as a member, log twenty professional-development units each year and never re-sit. The middle route means that climbing the ladder costs less than standing still. LPIC-2 is issued only to a holder whose LPIC-1 is active, so anyone planning both should treat the pair as one programme and sit 202 inside the LPIC-1 window; an LPIC-1 allowed to lapse first has to be earned again before LPIC-2 can be granted.

• LPIC-1 for the self-taught administrator on Debian or Ubuntu machines who wants a syllabus to audit against. LPI publishes the material free, so the objectives can be worked for months before a booking.
• **RHCSA** where the current or intended employer runs Red Hat Enterprise Linux. It sets tasks on live systems and grades what survives a reboot: work done under a clock rather than work described. Three years, English only, and Red Hat publishes neither a duration nor a cut score.
• **Linux+** for a holder already inside CompTIA's renewal system who wants one pool of continuing-education units. On its own it is one English exam, valid three years, which no higher CompTIA certificate renews.
• LPIC-2 once the work involves the services other people depend on: name resolution, mail, file sharing, storage, the kernel itself. At that level the certificate describes a job title, and it requires an active LPIC-1.
• No Linux certificate for the full-time administrator with visible evidence; the study weeks are better spent on what the record does not yet cover, most often containers or automation.
