CompTIA Linux+ validates the competencies required of an early career system administrator supporting Linux systems.

The new CompTIA Linux+ is for the IT pro who will use Linux to manage everything from cars and smartphones to servers and supercomputers, as a vast number of enterprises use Linux in cloud, cybersecurity, mobile and web administration applications.

In the new CompTIA Linux+, candidates are only required to pass one exam for certification. However, the new certification is no longer eligible for the LPI 2-for-1 offer.

  • CompTIA Linux+ is the only job-focused Linux certification covering the latest foundational skills demanded by hiring managers.
  • Unlike other certifications, the new exam includes performance-based and multiple-choice questions to identify the employees who can do the job.
  • The exam covers tasks associated with all major distributions of Linux, setting the foundation for advanced vendor/distro-specific knowledge.
  • CompTIA Linux+ covers common tasks in major distributions of Linux, including the Linux command line, basic maintenance, installing and configuring workstations, and networking.
