MB-910 Describe Dynamics 365 Customer Insights Practice Question
This MB-910 practice question tests your understanding of describe dynamics 365 customer insights. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 business analyst wants to create a segment of customers who have purchased both a laptop and a mouse in the last 30 days. The data is stored in two separate tables: 'PurchaseHeader' and 'PurchaseLines'. What is the best approach?
Clue words in this question
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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the segment builder to add two conditions: one for product = Laptop and one for product = Mouse, both with date filter
Option C is correct because Dynamics 365 Customer Insights - Data segment builder allows you to add multiple conditions on the same entity (PurchaseLines) using AND logic, filtering for both 'Laptop' and 'Mouse' within the last 30 days. This approach directly queries the transactional data without requiring table unification or external tools, leveraging the platform's native segment creation capabilities.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Create a segment and use the 'AND' condition for both products
Why it's wrong here
A single condition cannot reference two different product rows; need to use multiple conditions or a subquery.
✗
First unify the two tables into one view, then segment
Why it's wrong here
Unification is for identity resolution, not for combining purchase details.
✓
Use the segment builder to add two conditions: one for product = Laptop and one for product = Mouse, both with date filter
Why this is correct
Multiple conditions with AND logic can capture customers with both products.
Clue confirmation
The clue word "best" in the question point toward this answer.

✗
Export the data to Power BI and create the segment there
Why it's wrong here
Segments should be created in Customer Insights for downstream use.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think they need to unify tables first (Option B) or use a single AND condition (Option A), when in fact the segment builder supports multiple conditions on the same entity with AND logic across different rows, which is the correct method for matching customers who bought both products.
Detailed technical explanation
How to think about this question
Under the hood, Customer Insights uses a Common Data Model (CDM) schema where PurchaseHeader and PurchaseLines are linked via a foreign key (e.g., PurchaseId). The segment builder translates conditions into SQL-like queries against the unified customer entity, applying date filters using the 'last 30 days' relative date function. In real-world scenarios, this approach ensures segments update dynamically as new transactions occur, avoiding stale data from static exports.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
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.
