Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The Marketing Cloud connector user lacks Read permission on the Account object in CRM.
Why it's wrong here
Marketing Cloud data extensions do not depend on CRM Account permissions.
- ✗
The Data Extension name contains spaces and special characters that Data Cloud's streaming engine rejects.
Why it's wrong here
Naming conventions alone do not typically cause 'Invalid DE Schema' errors compared to missing primary keys.
- ✗
The Marketing Cloud Engagement account was disconnected from the CRM org.
Why it's wrong here
Disconnection results in authentication errors rather than specific DE schema validation errors.
- ✓
The Marketing Cloud Data Extension lacks a defined primary key or uses unsupported data types.
Why this is correct
Data Cloud requires data streams from Marketing Cloud Data Extensions to have a primary key defined in Marketing Cloud.
