Which objective is emphasized when refreshing the Orders table to minimize impact?

• A. Minimize the number of new rows added
• B. Maximize incremental updates
• C. Recompute all data
• D. Reset data

Answer: (A)

Minimizing impact during a refresh means making the operation as lightweight as possible by touching only what actually changes. Focusing on minimizing the amount of new data added keeps I/O, compute, and downstream dependencies small, so the refresh is faster and less disruptive. This approach avoids the heavy work of a full rebuild or a reset, and it avoids generating excessive updates. In contrast, expanding updates would still increase the workload, recomputing all data is costly, and resetting data is disruptive and unnecessary for a low-impact refresh.
