Linux — CompTIA A+ Core 2 (220-1102) Practice Questions
Linux appears on the 220-1102 exam as one of several operating systems a support technician may encounter in the field, alongside Windows and macOS. Candidates are expected to recognize common distributions such as Ubuntu and CentOS, navigate the filesystem hierarchy, and use basic shell commands for file management and system information. The exam does not require deep Linux administration knowledge, but comfort with the command line and an understanding of how Linux differs from Windows in areas like user accounts and file permissions is tested. These skills reflect the reality that many workplace environments run Linux on servers, workstations, or embedded devices.
