File Permissions — CompTIA A+ Core 2 (220-1102) Practice Questions
File permissions control which users and groups can read, write, or execute files and directories, and are a core security and access-control concept tested on the 220-1102 exam. In Linux and macOS, permissions are represented as a set of bits for owner, group, and others, while Windows uses Access Control Lists to achieve similar goals. Technicians must understand how misconfigured permissions can expose sensitive data or prevent legitimate users from accessing needed resources. The exam tests both the concept of least-privilege access and the practical ability to view and modify permissions on each major platform.
