XK0-006 System Management Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  symlink original.txt link.txt

  Why it's wrong here

  No symlink command exists on Linux; the utility is ln with the -s flag. This invocation would simply fail as an unknown command. It tempts because the verb describes the intended action, but Linux exposes the operation through ln, not a standalone binary.

• ✓

  ln -s original.txt link.txt

  Why this is correct

  The -s flag instructs ln to create a symbolic link rather than a hard link, and argument order matters: the target original.txt precedes the new link name link.txt. This satisfies the requirement for a symlink pointing to original.txt.

• ✗

  ln original.txt link.txt

  Why it's wrong here

  Without -s, ln creates a hard link, which shares the same inode as original.txt rather than pointing to its path. Symbolic links need the -s flag. Hard links tempt because they also produce a second name for the file, but they cannot span filesystems or target directories.

• ✗

  ln -s link.txt original.txt

  Why it's wrong here

  The arguments are reversed: ln -s takes the target first, then the link name, so this creates original.txt pointing at link.txt. The stem requires link.txt as the link. It tempts because -s is the correct flag, but operand order determines which name becomes the symlink.
