Difficulty: HardmacOS and Linux Operating System Features and Tools

Match each macOS system feature or Linux/macOS command-line tool to its primary administrative function.

  • df -hDisplays file system disk space utilization in human-readable units.
  • sudo chown -RRecursively changes user or group ownership across a file and directory hierarchy using superuser privileges.
  • FileVaultEnables full-disk volume encryption to protect data at rest on macOS storage drives.
  • SMC resetRestores baseline low-level hardware control for thermal cooling fans, power buttons, and battery management on Mac computers.

Answer

'df -h' matches displaying file system disk space in human-readable units; 'sudo chown -R' matches recursively changing file/directory ownership under superuser rights; 'FileVault' matches enabling full-disk encryption on macOS volumes; 'SMC reset' matches resolving low-level hardware power and thermal fan issues.
Each tool matches its definitive system administration role: 'df -h' displays storage volume usage in human-readable format; 'sudo chown -R' recursively modifies file ownership across directory trees under superuser permissions; 'FileVault' provides native macOS full-disk encryption; and an SMC reset restores low-level power and thermal management functions.

Step-by-Step Solution

1
Analyze storage monitoring CLI tools
Map 'df -h' to the display of mounted file system disk utilization formatted in human-readable sizes (GB/MB).
The 'df' (disk free) utility checks overall volume utilization, and the '-h' flag converts raw block counts to human-readable units.
2
Analyze file system administrative CLI utilities
Map 'sudo chown -R' to recursively modifying file and directory ownership.
The 'chown' utility alters user/group ownership, the '-R' option traverses directories recursively, and 'sudo' ensures execution with elevated administrative rights.
3
Analyze macOS native security tools
Map 'FileVault' to full-disk volume encryption.
FileVault is the native macOS feature that encrypts the system disk to protect stored data from unauthorized access.
4
Analyze macOS hardware troubleshooting utilities
Map 'SMC reset' to restoring low-level power and thermal management features.
The System Management Controller (SMC) manages physical subsystem controls including thermal cooling fans, power button responsiveness, and battery charging logic.
