Exam MC-Con-201 Topic 1 Question 34 Discussion

Salesforce explicitly documents the required Data Graph structure and fields for Marketing Cloud Next personalization. The Data Graph should use Unified Individual as its primary DMO and include the appropriate relationship chain through Unified Link Individual and Individual to the applicable contact-point objects.
Within that structure, Salesforce specifically requires these fields:
Individual ID from the Individual object,
Email Address from Contact Point Email, and
Telephone Number from Contact Point Phone.
These identifiers allow Marketing Cloud Next to resolve personalized profile information to the proper communication contact points when rendering email and SMS content.
Option B incorrectly locates email address and telephone number directly on the Individual DMO. Those values belong to their dedicated contact-point DMOs. Option C incorrectly substitutes the Unified Individual Link ID for the required Individual ID.
This answer has particularly strong current documentation support: Salesforce published a dedicated Marketing Cloud Next knowledge article on March 12, 2026 listing exactly these three required fields. The uploaded master bank also keys A.
