A system administrator notices that there is a low level of available storage space on a file server. Which of the following should be implemented to limit the amount of storage space users can…

Disk shadowing (mirroring) duplicates data to another disk for redundancy, which does not restrict user storage consumption.

Disk compression reduces the physical space files occupy but does not impose a usage limit on individual users.

Disk quotas allow administrators to set hard or soft limits on the amount of disk space each user account can use on a volume or share. When a user reaches their quota limit, they are prevented from writing additional data, which directly controls consumption and protects available space for other users. This is the standard administrative control for storage governance on file servers.

Disk indexing catalogs file metadata to speed up search operations and has no effect on how much storage users can consume.
