About CompTIA Linux+
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.
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.
The new exam has an increased focus on the following topics: security, kernel modules, storage & visualization, device management at an enterprise level, git & automation, networking & firewalls, server side & command line, server (vs. client-based) coverage, troubleshooting and SELinux.
