In Salesforce Data Cloud, activation membership refers to the individuals or records that qualify for a specific segment and are eligible to be activated (e.g., sent to external systems like Marketing Cloud). Here’s the breakdown:

Data Segmentation Object (Option C):

Segments in Data Cloud are stored as Data Segmentation Objects, which include metadata about the segment (e.g., logic, filters) and its membership (the records/individuals that meet the criteria).

When configuring an activation target, you select the segment (and its membership) stored in the Data Segmentation Object to send to downstream systems.

Salesforce’s official documentation confirms that segments and their memberships are managed through the Data Segmentation Object (Source: Salesforce Data Cloud Implementation Guide, "Segmentation and Activation").

Why Other Options Are Incorrect:

Data Model Object (A): Represents the structured data model (e.g., standard or custom objects like Individual or Account) but does not store segment membership.

Data Activation Object (B): A distractor; no such standard object exists in Data Cloud. Activation is a process that uses the Data Segmentation Object.

Data Lake Object (D): Stores raw, unprocessed data ingested into Data Cloud and is not directly used for activation.

Conclusion: For activation membership, the consultant must select the Data Segmentation Object to reference the segment’s qualified members.
