Quick Answer
The answer is the Customer activities entity. This entity is the correct choice because Dynamics 365 Customer Insights uses it as a unified schema to store and manage all interactions between a donor and the organization, such as donations, email opens, and event attendance, each linked by a unique customer ID to establish clear donor-donation relationships. On the MB-910 exam, this tests your understanding of how Customer Insights unifies disparate data sources—like fundraising platforms and email systems—into a single view of donor behavior, with a common trap being to confuse this with the Contact or Account entity, which store static profile data rather than dynamic interactions. Remember the key distinction: activities are actions, profiles are people, so think “donor does donation” equals an activity.

A non-profit organization wants to use Dynamics 365 Customer Insights to better understand donor behavior. They have data from their fundraising platform, email marketing system, and event management software. Which entity should they use to establish relationships between donors and their donations?
Customer activities
Activities represent actions like donations and link to customer profiles.
Enrichment
Why wrong: Enrichment adds attributes, not activity relationships.
Measures
Why wrong: Measures are calculations, not relationship entities.
Segments
Why wrong: Segments group customers but don't link to activities.

Correct answer & explanation
Customer activities
In Dynamics 365 Customer Insights, the 'Customer activities' entity is specifically designed to store and manage interactions between a customer (donor) and the organization, such as donations, email opens, or event attendance. By unifying these activities under a common schema with a customer ID, you can establish relationships between donors and their donations, enabling analysis of donor behavior over time.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Related concept
Read the scenario before looking for a memorised answer.
Enrichment
Why it's wrong here
Enrichment adds attributes, not activity relationships.
Measures
Why it's wrong here
Measures are calculations, not relationship entities.
Segments
Why it's wrong here
Segments group customers but don't link to activities.
Common exam traps
The trap here is that candidates often confuse 'Customer activities' with 'Segments' or 'Measures,' thinking that grouping or calculating data is the same as establishing the underlying relationships, but Customer Insights requires the activity entity to first link the raw data before any segmentation or measurement can occur.
Detailed technical explanation
Under the hood, the 'Customer activities' entity in Customer Insights uses a unified activity schema that includes fields like ActivityId, CustomerId, ActivityType, and Timestamp, allowing you to map diverse data sources (e.g., donation records from a fundraising platform) to a common structure. This enables the system to automatically resolve relationships via the CustomerId foreign key, supporting time-series analysis and predictive models like churn or next-best-action. In a real-world scenario, a non-profit could use this to correlate donation frequency with email campaign opens, identifying which donors are most engaged.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
