Which options are used in the /etc/fstab file to designate a filesystem that uses quotas?

The designation of a filesystem that uses quotas in the /etc/fstab file is specified using the options "usrquota" and "grpquota." These terms refer to user quotas and group quotas, respectively, which are mechanisms that limit the amount of disk space and the number of inodes that individual users and groups can utilize on a filesystem.

When mounting a filesystem with quotas, including these options in the /etc/fstab file enables the quota management system for that filesystem. "usrquota" specifically applies quotas for individual users, while "grpquota" applies to groups, allowing for tailored control over resource usage based on both user and group needs.

The other terms in the provided choices do not accurately reflect the valid options used in the /etc/fstab file for enabling quotas. Understanding this configuration is essential for system administrators who want to implement disk space management strategies effectively.
