CompTIA is the leading association outlining the international technology community. Its purpose is to give a unified voice, global advocacy, and leadership, and to promote industry growth through standards, professional skill, education, and business solutions. The CompTIA Linux+ certification is one of many certification programs CompTIA has placed together.
CompTIA Linux+ (Powered by LPI) tests the basic usage and managerial tasks that are familiar to almost all Linux partitions and UNIX flavors. The one certification exam that you have to pass to achieve the CompTIA Linux+ certification (XK0-004) cover the same topics as the two exams that you have to pass to achieve LPIC-1 (LPI Level 1 — Linux Administrator) certification. As a bonus, after getting CompTIA Linux+, you can apply for and obtain the LPIC-1 certification directly.
