Jobs: 1) beacon 2) tunnel 3) listener. Bring exfil to foreground.
Work the drill
Answer on paper or in a terminal before revealing the ideal answer.
Ideal answer
exfil is not running; no fg command can bring it. fg %exfil errors.
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.
fg %1
Misconception. Brings beacon, not exfil — misreads question.
Remedy. Literal read: the name exfil is not in the list.
fg %exfil
Misconception. Syntax is valid but no matching job — errors.
Remedy. Still counts as "no command works" reasoning.
