The Red Hat Certified Specialist in Linux Diagnostics and Troubleshooting exam tests learners on their ability to discover, analyze, and fix common issues one may expect as a Red Hat Specialist, systems administrator, or DevOps engineer working with Linux. We'll learn how to handle issues related to system boot, package management, system files, network connectivity, application degradation, and authentication issues, as well as how to gather forensic information and handle any server issues we may encounter with a positive, curious mindset — and not abject terror.
