A user cannot save large files to a directory on a Linux server that was accepting smaller files a few minutes ago. Which of the following commands should a technician use to identify the issue?

Question

Options

• Apvdisplay
• Bmount
• Cdf -h
• Dfdisk -l

• A
  11% (3)
• B
  4% (1)
• C
  82% (23)
• D
  4% (1)

Explanation

The scenario describes a filesystem that was working but can no longer accept large files, which is a classic symptom of a full or nearly full disk. The df -h command (disk free, human-readable) displays disk space usage for all mounted filesystems, making it the ideal first diagnostic step. pvdisplay shows LVM physical volume details (not directly useful here), mount lists mounted filesystems but not their usage, and fdisk -l lists partition tables without showing free space.
