Frequently Asked Questions

Which Linux distribution should I learn first?
Start with Ubuntu or CentOS/Rocky Linux. Ubuntu is the most popular for cloud and development environments, while CentOS/Rocky is widely used in enterprise settings. The core concepts transfer across distributions, so focus on fundamentals over distro-specific features.
Is Linux administration still relevant with cloud and containers?
More than ever. Cloud instances run Linux, containers run on Linux, and Kubernetes nodes are Linux-based. Cloud and container technologies haven't replaced Linux admin skills — they've made them more valuable and added new layers of complexity.
Do I need to learn scripting?
Yes, it's essential. Bash scripting is a core competency for any Linux admin. Python is also highly valuable for automation, configuration management, and writing more complex tooling. Both are covered in Linux+ preparation.
What's the career progression?
IT Support / Helpdesk → Junior Linux Admin → Linux Systems Administrator → Senior Systems Administrator → Site Reliability Engineer (SRE) / DevOps Engineer / Infrastructure Architect. Kubernetes and cloud certifications open the path to SRE and DevOps roles.
