The correct answers are C and E. Instead of supplying an explicit device in /etc/fstab for mounting, you can also use LABEL or UUID to identify the intended partition. LABEL is a human-readable name that can be assigned to a partition using tools such as e2label, tune2fs, or gparted. UUID is a universally unique identifier that is automatically generated for each partition and can be obtained using tools such as blkid or lsblk. Using LABEL or UUID instead of device names can be useful for avoiding problems caused by device name changes, such as when adding or removing disks. For example, instead of writing something like this in /etc/fstab:
/dev/sda1 /mnt/example ext4 defaults 0 0
You can write something like this:
LABEL=example /mnt/example ext4 defaults 0 0
or
UUID=80b496fa-ce2d-4dcf-9afc-bcaa731a67f1 /mnt/example ext4 defaults 0 0
The other options are not valid ways to identify a partition in /etc/fstab. FIND, ID, and NAME are not supported by the mount command or the /etc/fstab file. For more information on how to use LABEL and UUID in /etc/fstab, you can refer to the following articles:
