Configure the permissions of /var/tmp/fstab
Copy the file /etc/fstab to /var/tmp/fstab. Configure the permissions of /var/tmp/fstab so that: the file /var/tmp/fstab is owned by the root user. the file /var/tmp/fstab belongs to the group root. the file /var/tmp/fstab should not be executable by anyone. the user natasha is able to read and write /var/tmp/fstab. the user harry can neither write nor read /var/tmp/fstab. all other users (current or future) have the ability to read /var/tmp/fstab.
