CERTIFIED-DATA-ANALYST-ASSOCIATE Question #30: Real Exam Question with Answer & Explanation
The correct answer is B: Gold. Gold is the layer data analysts use most because it contains clean, aggregated, business-ready data - think final reports, dashboards, and KPIs. Data has been fully refined, joined, and modeled for consumption, meaning analysts can query it without needing to understand raw data
Question
Which of the following layers of the medallion architecture is most commonly used by data analysts?
Options
- ANone of these layers are used by data analysts
- BGold
- CAll of these layers are used equally by data analysts
- DSilver
- EBronze
Explanation
Gold is the layer data analysts use most because it contains clean, aggregated, business-ready data - think final reports, dashboards, and KPIs. Data has been fully refined, joined, and modeled for consumption, meaning analysts can query it without needing to understand raw data pipelines.
Why the distractors are wrong:
- Bronze (E) holds raw, unprocessed ingested data - it's for engineers ingesting data, not analysts querying it.
- Silver (D) contains cleaned and conformed data but is still intermediate; it's primarily used by data engineers or advanced analytics engineers, not typical analysts.
- All layers equally (C) and None of these layers (A) both ignore the clear separation of concerns the medallion architecture is designed to enforce.
Memory tip: Think of the metals by value - Gold = highest value = most refined = analyst-ready. Just like gold is the most valuable metal, the Gold layer delivers the most valuable, decision-ready data.
