Data 360 Consultant Setup And Administration Practice Question
An administrator needs to modify the primary key of a custom Data Model Object (DMO) that already has active data streams mapped to it. What must the administrator do first?
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
✓
Delete all data stream mappings connected to the DMO before modifying the primary key.
Data Model Objects with active mappings or data flowing into them cannot have their primary keys or core schema structures modified without first removing the dependencies or mappings.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Export the DMO schema as XML, edit the primary key tag, and re-import.
Why it's wrong here
Data Cloud does not use XML schema file re-importation for DMO modifications.
- ✗
Disable the Data Space associated with the DMO temporarily.
Why it's wrong here
Disabling a Data Space is not required to change a DMO primary key; mapping removal is.
- ✗
Switch the DMO type from Custom to Standard in Object Manager.
Why it's wrong here
Object Manager does not manage Data Cloud DMOs.
- ✓
Delete all data stream mappings connected to the DMO before modifying the primary key.
Why this is correct
Schema modifications like primary keys require removing data mappings and sometimes purging data depending on the exact structural change.
