Which command creates an ext4 filesystem on a partition?
- A`mkfs.ext4 /dev/sda1` — formats the partition with an ext4 filesystem
- B`fsck.ext4 /dev/sda1` — formats the partition with an ext4 filesystem
- C`mount.ext4 /dev/sda1` — formats the partition with an ext4 filesystem
- D`tune2fs /dev/sda1` — formats the partition with an ext4 filesystem
Why this is the answer
mkfs.ext4 (or mkfs -t ext4) builds a fresh ext4 filesystem, destroying existing data. fsck checks a filesystem, mount attaches one, and tune2fs adjusts parameters of an existing ext filesystem.
