What is the primary function of an activation membership in Data Cloud?
Activation membership records which unified profiles currently satisfy a segment's criteria and are therefore eligible for activation to a target. It satisfies the stem's requirement by defining the exact profile set exported during activation, distinct from segment membership itself, which only tracks qualification without guaranteeing inclusion in an activation.
Why this answer
An activation membership in Data Cloud is the record that links a Unified Individual profile to a specific activation and tracks whether that profile qualified for the segment and was included in the activation export. It is the join between segment membership and activation delivery, enabling tracking of which profiles were sent to which downstream target and when. This is essential for auditing, troubleshooting, and re-activation logic.
Exam trap
Data 360 Consultant often tests the distinction between segment membership (who qualifies now) and activation membership (who was actually exported to a target), so candidates who conflate the two pick answers about segment criteria or DMO schemas.
How to eliminate wrong answers
Option A is wrong because data stream refresh scheduling is configured on the data stream itself (via ingestion schedules or connectors), not on activation memberships. Option C is wrong because the structural schema of a Data Model Object is defined by the DMO metadata and field mappings, not by activation membership records. Option D is wrong because activation memberships are not encryption keys — encryption for activation targets is handled by platform-level TLS and target-specific credentials, not by membership records.
