A+ 220-1102 — Domain 1: Operating Systems

About this course

Master the A+ Operating Systems objectives with a course built entirely around realistic, exam-style practice. These six timed tests immerse you in the tasks help-desk techs face every day: installing and upgrading Windows (UEFI/BIOS, partitions, imaging, recovery), configuring and maintaining systems (users and groups, services, updates, drivers, policies), and fixing what breaks using the right tool at the right moment. You’ll work through command-line scenarios with DISM, SFC, CHKDSK, bootrec, bcdedit, netstat, ipconfig, PowerShell basics, and Task Manager utilities. We round it out with macOS/Linux fundamentals—permissions, packages, filesystems, and common utilities—plus mobile OS basics, virtualization, remote tools, and client security (UAC, least privilege, NTFS/share permissions, and workstation hardening).Every question includes a detailed rationale for the correct choice and teaches why each distractor is wrong, so you learn to avoid common traps. Explanations act like mini-lessons, linking symptoms to logs, commands, and settings you’ll see on the job. Items are scenario-based, mixing GUI steps and CLI output so you can translate between screenshots and terminal text under time pressure.This course is test-only by design—perfect for focused reps. Study in short, consistent bursts: 15 minutes at a time. Take a mini-block, read the explanations carefully, and return tomorrow. Those small sessions compound; accuracy and speed rise quickly when you touch the material daily. Use the results to target weak areas, retest with fresh question orders, and build calm, repeatable troubleshooting habits. Finish Domain 6 confident that you can install, configure, and repair modern operating systems—fast, methodical, and exam-ready.DisclaimerCompTIA A+ is a registered trademark of CompTIA.
