Misconception bank
Each row below is a plausible wrong answer, the thinking that produces it, and the remedy that corrects the misconception. These are the foundation of the multiple-choice framing and the targeted feedback a student receives after answering.
hostname
Misconception. Shows only machine name, not kernel or architecture.
Remedy. Distinguish: hostname subset vs uname -a superset.
uname
Misconception. Default uname prints only kernel name, not full info.
Remedy. Memorize -a for "all".
lsb_release -a
Misconception. Distro-specific, not kernel-level. Also not always installed.
Remedy. Accept as alternate but canonical answer is uname -a.
