The governance lens is least privilege, purpose limitation, and honoring privacy operations against the individual profile. Use separate data spaces for each business unit supports the governance requirement because Data 360 implementations should minimize unnecessary access, avoid over-collection, and process deletion or consent requests at the profile level where Salesforce expects them. The safest design is explicit, auditable, and limited to the business purpose. 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. This is the nuance exam questions often test: the platform capability must match both the technical layer and the business timing requirement, not just sound related to data.
