What the exam expects
- Pick the Data 360 (formerly Data Cloud) tool that diagnoses a symptom: Refresh History, the error message file, a problem record DLO, Resolution Summary, Query Editor behaviour or unified lineage.
- Resolve common CRM connector failures, including OPERATION_TOO_LARGE and missing permissions on related objects.
- Read data stream versus DLO Refresh History and say which one reflects billable consumption.
- Make a missing source file raise a failure and an alert.
- Interpret identity resolution job statuses, and explain query-time and dashboard delays in policy enforcement.
Key terms:
- Refresh History: the record-level statistics tab on a data stream or DLO record home.
- Problem record DLO: the DLO, named PR_DLO_Name, holding rows dropped for data quality issues.
- Platform Integration User: the user every CRM data stream query runs as.
- Unified lineage: a visual graph of upstream and downstream dependencies across Data 360 objects.
