Quick Answer
The answer is configuring data sources and defining data unification rules. Before you can create a unified customer profile in Dynamics 365 Customer Insights, you must first connect and configure your data sources—such as CRM, ERP, or transactional systems—so the platform can ingest customer records. Then, you must set up data unification rules, which define how to match and merge duplicate or conflicting records from these disparate sources into a single, cohesive identity. On the MB-910 exam, this question tests your understanding of the foundational setup steps for Customer Insights, often appearing as a "which two" scenario where common traps include selecting "create a segment" or "build a dashboard" too early. Remember that unification is a prerequisite for segmentation, not the other way around. A helpful memory tip: think of "Sources first, then rules" to recall that you cannot unify data you haven't yet connected.
This MB-910 practice question tests your understanding of describe dynamics 365 customer insights. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 company is implementing Dynamics 365 Customer Insights. Which TWO are required before you can create a unified customer profile?
Define data unification rules
Required to match and merge records.
Create a measure
Why wrong: Done after unification.
Create a segment
Why wrong: Done after unification.
Enrich customer profiles
Why wrong: Optional step after unification.
Configure data sources
Required to bring in data.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Define data unification rules
Option A is correct because data unification rules define how to match and merge customer records from different data sources into a single, unified profile. Without these rules, the system cannot resolve duplicate or conflicting data, which is essential for creating a cohesive customer identity.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates confuse the sequence of steps in Customer Insights, assuming that analytical outputs like measures or segments are prerequisites, when in fact they are dependent on the unified profile being created first.
Detailed technical explanation
Under the hood, Dynamics 365 Customer Insights uses a multi-step data ingestion pipeline: first, data sources are configured to bring in raw data from CRM, ERP, or external systems. Then, data unification rules apply deduplication and matching algorithms (e.g., fuzzy matching on email or phone) to merge records into a single customer entity. This unified profile is stored in a dedicated data lake, enabling downstream analytics like measures and segments. A real-world scenario is a retailer merging online and in-store purchase histories; without unification rules, the same customer might appear as two separate profiles.
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.
