The answer is to use the 'Delete data' option in the Customer Insights admin portal. This is the correct approach because Customer Insights is the primary system of record for unified customer profiles, and its built-in deletion feature ensures that all associated activities, relationships, and profile data are permanently removed from the Customer Insights data store to fulfill a GDPR deletion request, without requiring changes to source systems or retention policies. On the MB-910 exam, this question tests your understanding that GDPR data deletion must be executed within the tool that holds the unified view, not in the underlying source systems—a common trap is assuming you need to delete from Dynamics 365 Sales or Marketing separately. Remember the memory tip: "Unify then delete"—you must delete the unified profile in Customer Insights first, because that is where the complete customer picture lives.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the 'Delete data' option in Customer Insights admin portal
Option C is correct because Customer Insights provides a built-in 'Delete data' option in the admin portal that allows administrators to delete all data for a specific customer profile, including associated activities and relationships, to comply with GDPR deletion requests. This feature ensures that the deletion is performed within the Customer Insights data store, which is the primary system of record for unified customer profiles, without requiring changes to source systems or retention policies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse deleting data in Customer Insights with deleting data in source systems, assuming that removing records from source systems (Option D) or reconfiguring data sources (Option B) will automatically propagate the deletion to Customer Insights, when in fact Customer Insights maintains its own independent copy of the data.
Detailed technical explanation
How to think about this question
Under the hood, Customer Insights uses a data integration pipeline that ingests data from source systems into Azure Data Lake Storage, where it is processed and unified into customer profiles. The 'Delete data' option triggers a cascading deletion that removes the customer's profile, all associated activities, and any derived insights (e.g., measures, segments) from the Customer Insights environment, while leaving source system data untouched. In a real-world scenario, if a customer requests deletion under GDPR, the administrator must first verify the customer's identity, then use the 'Delete data' option with the customer's unique identifier (e.g., CustomerId) to ensure complete removal, and finally confirm the deletion via audit logs.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
