To synchronize subscriber data and unsubscribe statuses across all child business units in an Enterprise 2.0 Marketing Cloud account to an external CRM, the appropriate data views to query are _Subscribers and
_BusinessUnitUnsubscribes.
* _Subscribers Data View: This data view contains information about all subscribers in the Marketing Cloud account, including their Subscriber Key, Email Address, Status (e.g., Active, Unsubscribed, Bounced, Held), and other attributes. It is essential for identifying subscribers and their current status across the enterprise account.
* Why it's needed: The question specifies finding subscribers in the Marketing Cloud account, which requires querying the _Subscribers data view to retrieve subscriber details.
* _BusinessUnitUnsubscribes Data View: This data view tracks unsubscribe events at the business unit level, including the Subscriber Key, Business Unit ID, Event Date, and other details for each unsubscribe event. It is critical for capturing unsubscribe data across child business units in an Enterprise 2.0 account, as it provides a consolidated view of unsubscribe activities specific to each business unit.
* Why it's needed: The question emphasizes capturing unsubscribe data for child business units, which _BusinessUnitUnsubscribes uniquely provides.
Why the other options are incorrect:
* A. _Complaint: This data view tracks email complaints (e.g., when a subscriber marks an email as spam). While related to subscriber behavior, it does not capture general unsubscribe events or subscriber status, making it irrelevant for this use case.
* B. _Unsubscribe: This data view records unsubscribe events but is limited to the context of the parent business unit and does not provide business unit-specific unsubscribe data for child business units. In an Enterprise 2.0 account, _BusinessUnitUnsubscribes is required for cross-business unit tracking.
