Explanation

Overwrite is correct because when a DataSource delivers an additive-image delta, each incoming record already represents the incremental change for a key combination. The DataStore Object (advanced) is architected to handle these deltas natively through its own change-log mechanism - your job in the transformation is simply to pass the delta value through unchanged. Selecting Overwrite does exactly that: it writes the incoming value as-is into the activation queue, then the DSO's internal processing correctly accumulates the changes against active data.

Why the distractors are wrong:

• Summation (C): Would aggregate delta values before the DSO's delta mechanism runs, effectively double-accumulating changes and corrupting totals.
• Maximum (D) / Minimum (E): These replace the written value with the higher or lower of two values - meaningless for incremental change records where direction (positive/negative) carries the business meaning.

Memory tip: Think "additive delta = trust the DSO, Overwrite the transformation." The word additive belongs to the DSO's layer, not the transformation's aggregation rule. If you pick Summation thinking "additive means sum," you're adding twice - once in the transformation, once in the DSO - which is the trap the question is testing.
