Data 360 Consultant Data Ingestion And Modeling Practice Question
A consultant maps a custom Data Source Object (DSO) field to a standard Individual Data Model Object (DMO) field in Data Cloud. After refreshing the data stream, the identity resolution rules are not picking up the new records. What is the likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Identity Resolution ruleset must be manually rerun or has a scheduled frequency that has not yet triggered.
Identity Resolution Rules in Data Cloud rely on specific reconciliation rules and match rules that must include the mapped fields (e.g., email or phone). If the mapping is incorrect or the fields used in the match rules are unpopulated, identity resolution will fail to link them.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Standard DMOs do not support custom DSO fields unless wrapped in a Profile DMO extension.
Why it's wrong here
Standard DMOs can map custom DSO fields to standard or custom attributes.
- ✓
The Identity Resolution ruleset must be manually rerun or has a scheduled frequency that has not yet triggered.
Why this is correct
Identity resolution rulesets run on a schedule or can be triggered manually; new mappings do not instantly re-evaluate existing rulesets without a run.
- ✗
The data stream must be deleted and recreated for Identity Resolution to recognize new mapping paths.
Why it's wrong here
Deleting data streams is never required for updating mappings.
- ✗
Harmonization requires an intermediate Master Data Model object before matching can take place.
Why it's wrong here
Harmonization maps DSOs directly to DMOs.
