LFCS (Linux Foundation Certified System Administrator)<\/strong> is the certification for those who prefer to prove themselves in practice: no multiple choice \u2014 you get a terminal and a list of real administration tasks to solve against the clock. It is maintained by the Linux Foundation<\/a> itself, the home of the kernel. This post is part of our Linux certification series \u2014 see also LPIC-1<\/a>, RHCSA<\/a> and CompTIA Linux+<\/a>.<\/p>\n The exam is 100% hands-on<\/strong> (performance-based): 2 hours<\/strong> in a real Linux terminal, taken online with remote proctoring, with no prerequisites. The certification is valid for 3 years<\/strong>. Registration usually includes an official simulator and a second attempt at no charge \u2014 check the current terms on the Linux Foundation's page. The exam environment runs a current distribution (currently based on Ubuntu LTS); the concepts, however, apply to any distro.<\/p>\n The weights are those published at the time of publication \u2014 check the official page before scheduling, because the Linux Foundation revises the domains periodically.<\/p>\n In LFCS, knowing \u201cwhat to do\u201d is not enough \u2014 you need to execute quickly<\/em>. Two hours fly by when each task involves creating a logical volume, formatting it, mounting it with a specific option, and making it persistent in Golden rules: learn to find answers in the The terminal, storage, networking, and systemd foundations tested by LFCS are exactly the path covered by the Linux course by Gabriel (Toca do Tux)<\/a> \u2014 in Portuguese, from scratch to administration, with a two-hour block devoted entirely to partitions and file systems (the domain that trips up the most candidates). After the course, practice timed labs until you are fluent.<\/p>\n If LPIC-1 proves that you know<\/em>, LFCS proves that you do<\/em>. Together, the two make an impressive calling card. \ud83d\udc27<\/p>","protected":false},"excerpt":{"rendered":" LFCS (Linux Foundation Certified System Administrator) is the certification for people who prefer to prove their skills in practice: no multiple-choice questions \u2014 you receive a terminal and a list of real administration tasks to solve against the clock.
