Specialization - 4 course series

This specialization provides comprehensive preparation for the CompTIA Linux+ (XK0-006) certification and equips learners with the Linux administration skills demanded by modern IT, cloud, and DevOps environments. Spanning four modular courses and approximately 16 hours of expert video instruction, the specialization covers all Linux+ exam domains: System Management, Security, Scripting/Containers/Automation, and Networking/Storage/Troubleshooting.

Applied Learning Project

Learners benefit by developing practical, vendor-neutral Linux skills directly applicable to roles such as Linux administrator, systems engineer, cloud engineer, and DevOps practitioner. The specialization follows the logical progression of a Linux administrator's skill development, from foundational installation and file management through networking, security hardening, container management, and automation scripting. By the end of this specialization, learners will be able to install, configure, secure, automate, and troubleshoot Linux systems in enterprise and cloud environments.
