The answer is matching customer records from different sources and deduplication, as these are the two core actions performed during the data unification process in Dynamics 365 Customer Insights. This process is technically designed to resolve fragmented customer data by first identifying duplicate records across disparate source systems—such as CRM, ERP, or marketing databases—and then merging them into a single, unified customer profile. The matching step uses rules to link records that represent the same person, while the merging step consolidates attributes to eliminate redundancy, ensuring a single source of truth. On the Microsoft Dynamics 365 Fundamentals CRM MB-910 exam, this concept tests your understanding of how Customer Insights builds a 360-degree view; a common trap is confusing data unification with simple data import or transformation, which are separate preliminary steps. Remember the memory tip: "Match then merge" — think of it as finding the twins before combining their files.
MB-910 Describe Dynamics 365 Customer Insights Practice Question

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.
Which TWO actions are performed during the data unification process in Dynamics 365 Customer Insights?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Merging duplicate records into a single profile
Option A is correct because the data unification process in Dynamics 365 Customer Insights includes deduplication, where duplicate records from the same or different sources are merged into a single, unified customer profile. This step ensures that each customer is represented once, eliminating fragmentation and providing a single source of truth.
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 the 'data unification' step (matching and merging) with later steps like enrichment, measure creation, or segmentation, leading them to select options that are valid in Customer Insights but not part of the unification process.
Detailed technical explanation
How to think about this question
Under the hood, the data unification process in Customer Insights uses a two-stage pipeline: first, 'Matching' identifies duplicate or related records across data sources using deterministic or probabilistic rules (e.g., fuzzy matching on email or phone), then 'Merging' consolidates those matched records into a single profile by applying conflict-resolution rules (e.g., source priority or last-updated timestamp). In a real-world scenario, a retail company might unify data from its e-commerce platform and in-store POS system, matching customers by email and phone, then merging purchase histories to create a 360-degree view.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.

Variation 1. Which TWO activities are part of the data unification process in Dynamics 365 Customer Insights?
easy
A.Creating segments based on customer attributes
✓ B.Configuring match rules to identify duplicates
✓ C.Mapping data fields from source systems
D.Defining measures for customer metrics
E.Enriching profiles with external data
Why B: Option B is correct because configuring match rules is a core step in the data unification process in Dynamics 365 Customer Insights. Match rules define the conditions (e.g., fuzzy matching on email or phone) used to identify duplicate customer records across source systems, enabling deduplication and merging into a single unified profile. This is distinct from segmentation or enrichment, which occur after unification.
