Sample CompTIA A+ Core 2 2022 questions

1. A Windows 10 workstation needs a clean reinstall, and the technician must ensure the existing user data is removed from the target system. Which installation method is most appropriate?
  1. An in-place upgrade that keeps personal files and apps
  2. A clean installation after backing up needed data
  3. A repair installation that preserves user profiles
  4. A feature update from Windows Update

Answer: B. A clean installation after backing up needed data

A clean installation replaces the existing OS installation, so needed files should be backed up first. An in-place upgrade and repair installation are intended to preserve existing data or settings.

2. A support technician wants to open the Windows console that displays disk partitions and allows a drive letter to be assigned to a volume. Which utility should the technician use?
  1. Device Manager
  2. Task Scheduler
  3. Disk Management
  4. Resource Monitor

Answer: C. Disk Management

Disk Management is the Windows graphical utility for viewing and managing disks, partitions, volumes, and drive letters. Device Manager manages hardware devices and drivers, not partitions.

3. A user reports that a Windows application freezes at startup. The technician wants to launch Windows with only essential drivers and services to determine whether a third-party startup item is responsible. Which mode should be used?
  1. Safe Mode
  2. Sleep mode
  3. Hibernate mode
  4. Windows Sandbox

Answer: A. Safe Mode

Safe Mode loads a limited set of drivers and services, helping isolate problems caused by other software or startup components. Sleep and hibernate are power states, and Sandbox is an isolated environment rather than a startup troubleshooting mode.

4. A technician needs to check and repair protected Windows system files from an elevated command prompt. Which command is designed for this task?
  1. chkdsk /f
  2. diskpart
  3. format
  4. sfc /scannow

Answer: D. sfc /scannow

The System File Checker command sfc /scannow scans protected system files and attempts to repair corrupted files. CHKDSK checks file-system and disk errors, while DISKPART and FORMAT manage disks and volumes.

5. On a Linux computer, a user needs to list files in the current directory, including hidden files, in a long format showing permissions and ownership. Which command is appropriate?
  1. pwd -l
  2. ls -la
  3. cd -a
  4. chmod -l

Answer: B. ls -la

The ls command lists directory contents; -l requests the detailed format and -a includes hidden entries. pwd prints the working directory, while chmod changes permissions.
