Quick Answer
The correct answer is to create separate data partitions within Customer Insights and assign access permissions accordingly. This approach works because data partitions allow you to logically isolate subsidiary data within a single environment, while role-based access controls ensure that each subsidiary’s users see only their own partition, and corporate users with elevated permissions can view all partitions. On the MB-910 exam, this scenario tests your understanding of how Customer Insights handles multi-tenant data isolation without requiring separate environments—a common trap is assuming you need multiple instances or manual filtering. Remember the key principle: partitions separate the data, roles control the view. A useful memory tip is “Partitions for privacy, roles for reach”—the partition creates the wall, and the role decides who can see over it.

Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A large enterprise uses Dynamics 365 Customer Insights to manage customer data from multiple subsidiaries. They want to ensure that each subsidiary can only see their own customer data but the corporate team can see all data. What is the best approach?

Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Create separate data partitions within Customer Insights and assign access permissions accordingly
Data partitions allow segmentation of data and access control.
Create separate segments for each subsidiary
Why wrong: Segments are for grouping, not access control.
Apply enrichment filters to hide data
Why wrong: Enrichment doesn't control visibility.
Use match rules to keep data separate
Why wrong: Match rules unify data, not separate it.

Correct answer & explanation
Create separate data partitions within Customer Insights and assign access permissions accordingly
Data partitions in Dynamics 365 Customer Insights allow you to logically separate data from different sources (e.g., subsidiaries) within a single environment. By assigning role-based access permissions to each partition, you ensure that subsidiary users can only view their own partition data, while corporate users with broader permissions can access all partitions. This is the designed mechanism for multi-tenant or multi-business-unit data isolation without duplicating infrastructure.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Create separate segments for each subsidiary
Why it's wrong here
Segments are for grouping, not access control.
Apply enrichment filters to hide data
Why it's wrong here
Enrichment doesn't control visibility.
Use match rules to keep data separate
Why it's wrong here
Match rules unify data, not separate it.
Common exam traps
The trap here is that candidates confuse segments (which are just filtered views of data) with security boundaries, assuming that creating separate segments for each subsidiary would restrict visibility, but segments do not enforce access control at the data level.
Detailed technical explanation
Data partitions in Customer Insights are implemented at the data source level, where each partition maps to a unique Azure Data Lake Storage container or folder. Access is controlled via Azure Active Directory (Azure AD) roles and Customer Insights security roles, which can be scoped to specific partitions using the 'Read' permission on the partition entity. In a real-world scenario, a global enterprise might have subsidiaries in different regions with GDPR or local data residency requirements; partitions ensure that a European subsidiary cannot accidentally view North American customer data, while the corporate team uses a global admin role to query across all partitions.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
