A systems administrator is enabling quotas on the /home directory of a Linux server.
The administrator makes the appropriate edits to the /etc/fstab file and attempts to issue the commands to enable quotas on the desired directory.
However, the administrator receives an error message stating the filesystem does not support quotas.

https://www.tecmint.com/set-filesystem-disk-quotas-on-ubuntu/The error message "the filesystem does not support quotas" indicates that the filesystem on which the /home directory is located does not have quota support enabled. To enable quotas on a filesystem, it must be mounted with the appropriate options in the /etc/fstab file.
The first step is to edit the /etc/fstab file and add the appropriate options to the line for the filesystem on which the /home directory is located. Typically, the options for enabling quotas are "usrquota" and "grpquota". For example, the line in /etc/fstab for the filesystem on which the /home directory is located might look like this:
bash/dev/sda1 /home ext4 defaults,usrquota,grpquota 0 2
After making the changes to /etc/fstab, save the file and run the following command to remount the filesystem with the new options:
bashmount -o remount /home
Next, run the quotacheck command to scan the filesystem and create the necessary quota files:
bashquotacheck -cg /home
The -c option tells quotacheck to create new quota files if they don't already exist, and the -g option tells it to check group quotas as well as user quotas.
Finally, run the following command to turn on quota enforcement on the /home directory:
bashquotaon /home
This will enable the quotas that have been set up on the filesystem.
In summary, the correct answer is A: mount -o remount /home.
