CompTIA A+ Core 2 220-1202 Skills Measured

Operating Systems covers support knowledge for Windows, macOS, Linux, and mobile operating systems. Study installation and configuration concepts, command-line tools, system utilities, user and file management, updates, startup behavior, and common administrative tasks that support end users.

Security covers practical endpoint protection and user-safety decisions. Expect concepts such as authentication, permissions, malware prevention and response, wireless and browser security basics, data protection, password practices, social engineering awareness, and secure support habits.

Software Troubleshooting covers diagnosing operating-system, application, malware, mobile OS, and security-related symptoms. Focus on recognizing likely causes, choosing safe first steps, using appropriate tools, and verifying that the user issue is resolved.

Operational Procedures covers the professional side of support work: documentation, change awareness, backups, safety, environmental handling, communication, professionalism, privacy, and escalation. These questions often test the best process, not just the most technical action.
