A mid-size city sketches an ecosystem diagram and places a serving dashboard in the ingestion layer while putting Kafka-style collection in the serving layer. Which correction reflects conceptual ecosystem roles?
Select an answer to reveal the explanation.
Short Explanation
Layers are jobs on an assembly line, not stickers you can peel and swap for fun. Ingestion brings data in, storage holds it, processing works it, and serving shows results. Put the dashboard at the end of the line and the collection bus at the start.
Full Explanation
At a conceptual BDPC level, Big Data ecosystems separate concerns: ingestion for collection and movement, storage for persistence, processing for transformation and analysis, and serving for delivering insights to users or applications. Swapping serving dashboards into ingestion and collection mechanisms into serving confuses those roles. Accurate layering supports clearer architecture and tool choices later in the syllabus.
