Exam 220-1202 Topic 1 Question 123 Discussion

Linux is the best choice for a low-cost home lab built from used PCs because it is free/open source and widely used in server environments, making it ideal for practicing server administration and scripting. Quentin Docter explains that Linux was created as a free, open source OS and that it can function as both a workstation OS and a server OS depending on installation and configuration-exactly what a lab for
"managing servers" needs. The All-in-One guide also highlights that Linux was made "freely available for everyone," reinforcing why it fits a low-cost requirement (no licensing cost). Mike Meyers' Lab Manual similarly describes Linux as a "popular, free, open source" OS and emphasizes the importance of the command line-critical for scripting and automation in admin tasks.
By comparison, macOS requires Apple hardware, Windows typically requires licensing costs, and ChromeOS is designed as a cloud-based/stateless OS centered on web apps and Google Drive, making it less suitable for broad server scripting labs.
