The CompTIA Linux+ (XK0-005) Literacy (Beginner Level) benchmark measures your beginner-level experience with the Linux operating system. You will be evaluated on your ability to use Linux file system management and security commands, manage standard Linux file system permissions and network connectivity, and secure a Linux system. A learner who scores high on this benchmark demonstrates that they have a beginner-level understanding of the Linux server technology platform and vocabulary.
