Multiple choiceMediumchapter-4-curatedpremiumdata-cleanupsafe-output-writes

Keep safe output writes implicit so the script stays short and hope the next engineer infers the rule.Delay clarity until production traffic reveals the edge case and then patch it under pressure.Use safer write patterns when downstream consumers depend on the file existing in a coherent final state.Solve the symptom with comments only and avoid changing the code shape around safe output writes.

Answer and explanation

Correct answer

C. Use safer write patterns when downstream consumers depend on the file existing in a coherent final state.

Why

Use safer write patterns when downstream consumers depend on the file existing in a coherent final state. That is the stronger engineering move because interviewers notice candidates who think about partially written artifacts and downstream consumers. If a process dies mid-write and the target file was already replaced, the next job may read corrupt output.
