LFCS · Question #873
Instead of supplying an explicit device in /etc/fstab for mounting, what other options may be used to identify the intended partition? (Choose TWO correct answers.)
The correct answer is C. LABEL E. UUID. In the /etc/fstab file, partitions can be identified for mounting by their volume LABEL or their Universally Unique Identifier (UUID) instead of their device name.

Why each option
In the /etc/fstab file, partitions can be identified for mounting by their volume LABEL or their Universally Unique Identifier (UUID) instead of their device name.
FIND is not a standard identifier used in /etc/fstab for specifying partitions.
ID is not a standard identifier used in /etc/fstab for specifying partitions; while UUID contains an ID, "ID" itself is not the keyword.
Using LABEL allows administrators to specify a partition by its assigned filesystem label, which is a persistent identifier that remains consistent across reboots and device reordering, making it more reliable than mutable device names.
NAME is not a standard identifier used in /etc/fstab for specifying partitions; device names like /dev/sda1 are physical paths, not logical "NAME" keywords.
UUID (Universally Unique Identifier) provides a globally unique string for each filesystem, ensuring that the correct partition is always mounted regardless of device name changes or hardware configuration variations, thereby enhancing system robustness.
