IT & Cybersecurity
CompTIA® Linux+Linux Certified IT Professional
CompTIA Linux+ validates the Linux administration skills needed for systems, security, DevOps, and cloud roles. The current exam is XK0-006 (V8), launched July 15, 2025; the prior XK0-005 retired in English on January 13, 2026. V8 significantly expanded coverage of automation, containers, and infrastructure-as-code to reflect modern Linux ops work. The five domains span system management, services and user management, security, automation and scripting, and troubleshooting. Unlike RHCSA, Linux+ is distribution-neutral and includes performance-based questions on Ubuntu, Red Hat, and other major distros that most US enterprise shops actually run.

Who it’s for
Built for the people taking this exam.
Linux systems administrators, junior DevOps engineers, and cybersecurity practitioners who need to defend or audit Linux environments. A common stepping stone before RHCSA or LFCS for candidates who want a distribution-neutral baseline first rather than committing to the Red Hat ecosystem.
Why it matters in 2026
The career signal.
Linux+ is the only vendor-neutral Linux cert on most federal contractor approved lists and is increasingly required for SOC analyst and incident response roles, where the majority of servers under investigation run Linux. The V8 (XK0-006) refresh added container, IaC, and automation coverage that hiring managers explicitly look for on entry-level DevOps and cloud-engineer resumes. It is also accepted as a substitute for vendor-specific Linux credentials at many MSPs, broadening the employer pool.
Sample question
What a CompTIA® Linux+ question looks like.
An administrator needs to bundle several directories into one archive file while keeping file permissions and folder structure intact. Which command is the right tool for this job?
Why: tar bundles multiple files and directories into a single archive, preserving permissions and the original structure. gzip compresses individual files but cannot aggregate multiple directories on its own. unzip is an extraction utility for ZIP archives and serves no archiving purpose. touch is used to create empty files or update timestamps, not to create archives.
