- Certification: Salesforce Data 360 Consultant
- Exam section: Data Activations and Utilization
- Study guide: https://www.certifyforce.com/study-guide/data-360-consultant

**Official exam objective:**

> Manage segments within Data 360.

## What the exam expects

- Choose standard, real-time, waterfall, dynamic or nested segments from a latency, exclusivity or reuse requirement.
- Configure standard versus rapid publish schedules and explain what can't be changed after creation.
- Read Segment Status and Publish Status values, and find who was in the last publish.
- Apply segment limits (9,950 active segments, 20 rapid, 50 filters per tab) and the composite-key join limitation.
- Lower segmentation credit use through schedule, lookback and nesting choices.

Key terms:
- **Rapid Publish:** a daily schedule at a 1-hour or 4-hour interval, chosen when the segment is created.
- **Waterfall segment:** a priority-ordered list of segments that yields mutually exclusive audiences.
- **Dynamic segment:** a segment with runtime placeholder filters whose results aren't stored in Segment Membership DMOs.
- **Nested segment:** an outer segment that reuses an inner segment.
- **Segment Membership DMO:** the object created or updated on each publish that records who is in the segment.

## Check yourself

- Why can't a waterfall reuse a segment that's already in another waterfall?
- When does a scheduled segment start later than its scheduled time?
- Which object tells you exactly who was in the last publish?
- Why do composite-key DMOs give unreliable segment counts?
