An administrator has just added a CD-ROM drive (/dev/hdd) to a system and added it to the administrator's fstab. Typically the administrator can use which of the following commands to mount media in t

/dev/cdrom is a different device path than the /dev/hdd that was added and configured in fstab; this would reference an incorrect or non-existent device.

Specifying only a device without a mount point requires a corresponding fstab entry keyed to the device, but using /dev/cdrom is still the wrong device path here.

The '-t cdrom' option is not a valid filesystem type; cdrom is not a filesystem type recognized by mount.

Because /dev/hdd is already mapped to /mnt/cdrom in /etc/fstab, the mount command can resolve all remaining parameters from that file. Supplying only the mount point 'mount /mnt/cdrom' is sufficient and is the conventional shorthand administrators use when fstab entries are present.

'automount' is not a standard Linux command for manually mounting a device and the syntax shown is incorrect.
