Which command should a technician use to identify storage issues on a Linux server when large files cannot be saved?

• A. df -h
• B. du -sh
• C. ls -l
• D. fsck

Answer: (A)

The most suitable command for identifying storage issues on a Linux server, particularly when large files cannot be saved, is the command that reports filesystem disk space usage. This command displays the available disk space on the mounted filesystems in a human-readable format, allowing the technician to quickly ascertain whether a lack of available storage is causing the inability to save large files. When large files cannot be saved, it's often due to insufficient disk space. By using the command that shows disk space usage, a technician can verify whether the storage is full. If the output indicates that the filesystem is at or near capacity, this would explain the issue. While other commands also serve useful functions, they are not primarily designed to diagnose disk space problems. For example, one command provides a summary of disk usage for files and directories, while another lists detailed information about files in a directory. However, these do not directly report on available space across the entire filesystem. The command that checks and repairs filesystem inconsistencies, while important, is more relevant in the context of filesystem corruption rather than straightforward storage capacity.
