A technician wants to limit disk usage on a server. Which of the following should the technician implement?

Disk quotas are a system administration feature used to control and limit the amount of disk space that a user or group can consume on a file system volume. By implementing disk quotas, a technician can set specific storage limits (hard or soft quotas) for each user, preventing any single user from consuming an excessive amount of disk space. This directly addresses the requirement to "limit disk usage" on a server, ensuring fair allocation of resources and preventing the disk from filling up unexpectedly.

A. Formatting: This process prepares a disk partition for use by creating a file system; it erases data but does not impose ongoing usage limits.
B. Compression: This technique reduces the size of files to save space but does not prevent users from continuing to add data until the volume is full.
D. Partitioning: This divides a physical disk into separate logical volumes but does not control how much space a user can consume within a given partition. ---

In the "Overview of Disk Quotas" section, it states, "Disk quotas track and control disk space usage for volumes... You can use disk quotas to... specify the level of disk space at which to log an event and the level of disk space at which to deny users further disk space."

In the lecture notes covering file system management, the concept of quotas is introduced as a mechanism for administrators to "limit the amount of space a user can use."
