A Data 360 Consultant is performing a source system inventory for Northern Trail Outfitters (NTO).

The modeling decision should make the data understandable, reusable, and correctly related before segmentation or activation depends on it. Extend the relevant standard DMOs by adding custom fields to accommodate the missing data. fits because Data 360 depends on mappings and relationships between data lake objects and data model objects. Correct modeling lets the same attribute mean the same thing across source systems and prevents downstream users from building logic on ambiguous fields. The distractors fall short because they either move the problem into the wrong system, add needless duplication, ignore Data 360 object relationships, or rely on a feature built for a different lifecycle stage. In a real implementation, those choices usually create brittle pipelines, stale data, security exposure, or segments that look correct on paper but fail when activated. Thinking like an architect, the selected option places the logic where Data 360 can govern it and reuse it reliably.
