Free Databricks Certified Data Engineer Associate Actual Exam Questions - Question 7 Discussion

E imo, Silver tables usually hold filtered or summarized data, so they often have less volume than Bronze, which is raw data. That makes E a solid candidate since data size typically decreases after cleaning.

Maybe D is the best fit here since Bronze tables are typically the raw, unprocessed data layer, and Silver tables are where cleansing and transformations happen. That means Silver should always be cleaner or more refined. A and C don’t make much sense because Bronze is usually the source of raw data, so it can’t be less refined or smaller in volume than Silver all the time. E might be true in some cases but not guaranteed, especially if Silver includes extra columns or enriched data. So D feels like the safest bet for something that’s always true.

E imo, Silver tables usually have filtered or summarized data, so they often contain less data than Bronze tables, which are raw and full. That makes E a solid choice too, unlike C.

D. Silver tables are definitely more refined and cleaner compared to Bronze tables, which are raw or less processed. The other options don’t hold up because Silver doesn’t always aggregate data (so B is off), and it doesn’t necessarily have more or less data than Bronze (so C and E are shaky). A is just backwards since Bronze is the raw stage. So D is the only one that consistently fits.

Yeah, D feels right but I think B can be ruled out quickly—Silver tables don’t have to be aggregates, they can just be cleaned and enriched data. Also, A is the opposite of what’s true since Bronze is usually raw data. So sticking with D because it’s the only one that always fits the relationship between Silver and Bronze tables.

D, for sure. Silver is all about cleaning and refining compared to Bronze.

D seems solid since Silver always cleans up Bronze, right?

Option D sounds right since Silver tables are usually the cleaned-up version of Bronze. But I wonder if it’s always true that Silver tables have less data than Bronze (Option E)? Sometimes Silver might keep all records but just cleaned up, so the data volume might not always be less. Would help to know if the question assumes a specific implementation or just general principles here.
