XK0-006 Practice Question: A system administrator notices that the root…

A system administrator notices that the root filesystem is at 95% capacity. Which command should be used to identify the directories consuming the most space?

⚠ Common exam trap

Many candidates confuse `df -h` (filesystem-level overview) with `du -sh` (directory-level detail), mistakenly thinking `df` can pinpoint which directories are consuming space.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

du -sh /*

B is correct because `du -sh /*` calculates disk usage for each top-level directory under root, showing human-readable sizes. This directly identifies which directories consume the most space, allowing the administrator to pinpoint the source of the 95% capacity issue.

Answer analysis

Option-by-option breakdown

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

    df -h

    Why it's wrong here

    du -sh /*

    Why this is correct

    Shows size of each top-level directory.

  • ✗

    fdisk -l

    Why it's wrong here

  • ✗

    ls -la /

    Why it's wrong here

    Lists files, not sizes recursively.
