CCDV-F objective 2.4 · Domain 2 · 33.1% of the exam
Software Engineering Foundations
Ordinary engineering, examined where it meets a non-deterministic caller. Independent calls want bounded concurrency rather than a serial loop or an unbounded fan-out. A restructuring with patchy coverage wants current behaviour pinned first, defects included, so that one job is being done at a time. Retry safety belongs to the operation rather than to the transport, which is why a single policy across reads and writes produces duplicated side effects. An idempotency key is minted once for the intent and resent unchanged.
