What is a Linux certification?

Obtaining a Linux® certification demonstrates your proficiency with the Linux operating system. Many organizations in the open source community offer Linux certifications to prepare IT professionals with knowledge relevant in a real-world environment.

You may want to validate your skills, or maybe you must verify your Linux experience based on either your company’s requirements or mandate. Either way, certifications can be determined by performance-based exams, practical exams, or a combination of these. These methods are designed to test your capabilities with the tasks that Linux professionals should be able to perform.

There are many options out there to prepare you for a certification exam, but training courses are popular, as they can introduce you to realistic Linux-based enterprise environments, and common issues and tasks you may be expected to know. Red Hat® has Linux certification training allowing you to learn as you perform tasks in a virtual Linux environment—so you can experience real-world relevance in a classroom setting.

Training for certification

Certifications can be distribution-agnostic, or they can align with specific products. Red Hat has 2 Linux certifications: Red Hat® Certified System Administrator (RHCSA®) and Red Hat Certified Engineer (RHCE®).

The Red Hat Certified System Administrator has demonstrated core knowledge and system administration skills within Red Hat Enterprise Linux environments. The Red Hat Certified Engineer wants to take their expertise further, adding automation skills to their proficiency with Linux deployment and configuration.
