MB-910 Describe Dynamics 365 Customer Insights — Timed 100 Questions

Question 1

A company uses Dynamics 365 Customer Insights and notices that some customer records are duplicated after unification. They want to reduce duplicates without losing data. What should they do?

Accepted Answer

Run the deduplication process manually. Modifying the matching rules to be stricter reduces false-positive duplicate profiles by requiring more fields to match. This prevents over-merging of distinct customers, preserving data while eliminating unwanted duplicates.

Answer

Modify the matching rules to be stricter

Answer

Delete all duplicate records from the source systems

Answer

Increase the confidence score threshold for matching

Question 2

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?

Accepted Answer

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.

Answer

Enrichment

Answer

Measures

Answer

Segments

Question 3

You are reviewing the activity mapping configuration. The source system is Salesforce, and the target is Customer Insights. The mapping specifies that the CustomerId field is mapped from AccountId. What is the purpose of this mapping?

Accepted Answer

To specify which field in Salesforce corresponds to the customer identifier in the activity. The mapping specifies that the CustomerId in the activity corresponds to the AccountId field from Salesforce, which uniquely identifies the customer in the source system. Option A is incorrect because activity mappings map source fields to activity schema fields, not define relationships between customer profiles. Option B is incorrect because the mapping is for the CustomerId in the activity, not for the UnifiedCustomerId (which is created during unification). Option C is incorrect because this mapping is a field-level mapping, not a relationship creation between activity and customer entity.

Answer

To define the relationship between Salesforce and Customer Insights customer profiles

Answer

To map the UnifiedCustomerId to the Salesforce AccountId

Answer

To create a new relationship between the Purchase activity and the Customer entity

Question 4

A company wants to use Dynamics 365 Customer Insights to create a unified customer profile. The data sources include a CRM system, a loyalty program database, and web analytics. What is the first step they should take?

Accepted Answer

Configure data sources and ingest data. In Dynamics 365 Customer Insights, the first step to creating a unified customer profile is to configure data sources and ingest data. Without data ingestion, there is no customer data to unify, segment, or analyze. This foundational step connects the CRM system, loyalty program database, and web analytics to the platform, enabling subsequent unification and segmentation.

Answer

Define unification rules

Answer

Set up connections to Power BI

Answer

Create a customer segment

Question 5

A marketing team notices that a segment based on 'high-value customers' returns fewer records than expected. The segment criteria include 'Total Purchase Amount > $500' and 'Last Purchase Date within 90 days'. The data source is updated nightly. What is the most likely cause?

Accepted Answer

The segment was not refreshed after data update. The segment criteria are evaluated against the data at the time the segment is created or last refreshed. Since the data source updates nightly, the segment must be manually or automatically refreshed to incorporate the new data. If the segment was not refreshed after the nightly update, it would still reflect the older, smaller dataset, resulting in fewer records than expected.

Answer

The data source credentials are expired

Answer

The segment includes too many conditions

Answer

The customer profiles are not unified

Question 6

A manager wants to understand the lifetime value of customers and predict future purchases. Which capability of Dynamics 365 Customer Insights should they use?

Accepted Answer

Predictive models. Predictive models in Dynamics 365 Customer Insights use machine learning to analyze historical customer data, calculate lifetime value (CLV), and forecast future purchase behavior. This directly matches the manager's need to understand customer value and predict future actions, making option C the correct choice.

Answer

Segmentation

Answer

Data profiling

Answer

Data sources

Question 7

A company uses Customer Insights to manage customer data. They want to ensure compliance with GDPR by allowing customers to request deletion of their data. What is the recommended approach?

Accepted Answer

Use the 'Delete data' option in Customer Insights admin portal. Customer Insights provides a built-in 'Delete data' option in the admin portal that allows administrators to delete all data for a specific customer profile, including associated activities and relationships, to comply with GDPR deletion requests. This feature ensures that the deletion is performed within the Customer Insights data store, which is the primary system of record for unified customer profiles, without requiring changes to source systems or retention policies.

Answer

Change the data retention policy to zero days

Answer

Reconfigure Data sources to exclude the customer

Answer

Manually delete records from the source systems

Question 8

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?

Accepted Answer

Use the segment builder to add two conditions: one for product = Laptop and one for product = Mouse, both with date filter. 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.

Answer

Create a segment and use the 'AND' condition for both products

Answer

First unify the two tables into one view, then segment

Answer

Export the data to Power BI and create the segment there

Question 9

Which feature in Dynamics 365 Customer Insights allows you to combine data from multiple sources into a single customer view?

Accepted Answer

Data unification. Data unification in Dynamics 365 Customer Insights is the feature specifically designed to combine data from multiple sources—such as CRM, ERP, and transactional systems—into a single, unified customer profile. It uses matching and merging rules to identify and consolidate records that represent the same customer, resolving duplicates and creating a 360-degree view. This is the core mechanism for achieving a single customer view from disparate data sources.

Answer

Data export

Answer

Data profiling

Answer

Data transformation

Question 10

A Customer Insights administrator receives an error when trying to ingest a CSV file from Azure Blob Storage. The error message says 'Access denied'. What is the most likely cause?

Accepted Answer

The connection string or SAS token is invalid or expired. The 'Access denied' error when ingesting a CSV file from Azure Blob Storage into Dynamics 365 Customer Insights indicates that the service cannot authenticate to the storage resource. The most common cause is an invalid or expired connection string or Shared Access Signature (SAS) token, as these credentials are required for secure access to Azure Blob Storage. Without valid credentials, Customer Insights cannot read the file, regardless of its format, size, or schema.

Answer

The CSV format is incompatible

Answer

The CSV file is too large

Answer

The schema does not match the mapping

Question 11

A company has multiple business units that each use a separate CRM system. They want to use Customer Insights to create a single view of customers across these systems. Which feature should they use?

Accepted Answer

Data unification. Data unification is the correct feature because it is specifically designed to merge customer records from multiple data sources (such as separate CRM systems) into a single, unified customer profile. This process uses matching rules and deduplication to resolve identities across disparate systems, enabling a 360-degree view of each customer.

Answer

Measures

Answer

Data sources

Answer

Segments

Question 12

A marketing team wants to send personalized emails based on a customer's predicted churn risk. Which Customer Insights capability should they use?

Accepted Answer

Predictive models. Predictive models in Customer Insights use machine learning to analyze historical customer data and generate scores like churn risk. This enables the marketing team to automatically identify high-risk customers and trigger personalized email campaigns based on those predictions.

Answer

Data sources

Answer

Data unification

Answer

Segmentation

Question 13

During data unification, a large number of records are marked as 'unmatched'. The administrator wants to reduce this number. What is the best approach?

Accepted Answer

Adjust matching rules to be less strict. Adjusting matching rules to be less strict (e.g., lowering the similarity threshold or using fuzzy matching instead of exact match) allows more records to be considered as duplicates and merged, thereby reducing the number of unmatched records. In Dynamics 365 Customer Insights, matching rules define the conditions under which records from different data sources are considered the same customer profile, and making them less strict increases the recall of the unification process.

Answer

Increase the number of data sources

Answer

Skip the unification step

Answer

Delete the unmatched records

Question 14

A retailer uses Customer Insights to track customer interactions across online and offline channels. They notice that some customers have duplicate profiles. What is the first step to resolve this?

Accepted Answer

Run data unification with appropriate matching rules. Customer Insights provides a built-in data unification process that uses matching rules to identify and merge duplicate customer profiles. This is the recommended first step to resolve duplicates, as it leverages the platform's deduplication capabilities without manual intervention or data export.

Answer

Export data to Excel and deduplicate there

Answer

Create a segment of duplicates

Answer

Delete the duplicate profiles manually

Question 15

Which TWO of the following are valid data source types in Dynamics 365 Customer Insights?

Accepted Answer

Microsoft Excel. Microsoft Excel is a valid data source type in Dynamics 365 Customer Insights because it supports importing data from flat files, including .xlsx and .csv formats, via the ingestion pipeline. This allows users to bring in customer data from spreadsheets for unification and segmentation without requiring a database connection.

Answer

Oracle Database

Answer

Salesforce

Answer

Adobe Analytics

Question 16

Which THREE of the following are capabilities provided by Dynamics 365 Customer Insights?

Accepted Answer

Data ingestion from multiple sources. Dynamics 365 Customer Insights provides a unified data ingestion pipeline that can connect to multiple sources such as Azure Data Lake, Dataverse, Power Query connectors, and custom APIs. This allows organizations to bring in customer data from CRM, ERP, transactional systems, and external sources into a single customer data platform (CDP) for analysis and activation.

Answer

Inventory management

Answer

Invoicing

Question 17

A company wants to use Customer Insights to improve customer retention. Which TWO features should they use?

Accepted Answer

Segments (based on churn risk). Segments based on churn risk (Option B) allow you to group customers who are likely to leave, enabling targeted retention campaigns. Predictive models, specifically the churn model (Option D), use historical data and machine learning to calculate a churn probability score for each customer, which directly feeds into those segments. Together, they provide the actionable intelligence needed to proactively intervene and improve retention.

Answer

Data profiling

Answer

Data sources configuration

Answer

Data exports to external systems

Question 18

Which THREE of the following are prerequisites for using Customer Insights predictive models?

Accepted Answer

Data types that match the model requirements (e.g., numeric, categorical). Customer Insights predictive models require that the data types in your dataset match the model's expected schema—for example, numeric fields for regression or categorical fields for classification. If the data types are mismatched (e.g., a string where a number is expected), the model will fail to train or produce inaccurate predictions. This prerequisite ensures the underlying machine learning algorithms can process the data correctly.

Answer

Real-time data streaming

Answer

Power BI integration

Question 19

Contoso Ltd. is a multinational retailer using Dynamics 365 Customer Insights to unify customer data from three regional CRM systems (North America, Europe, Asia) and a global e-commerce platform. The company has configured data sources for each system and run data unification, but the unified customer profiles show a high number of duplicates (approximately 15% of profiles are duplicates). The administrator has tried increasing the match confidence threshold but the problem persists. Additionally, the company wants to ensure that customer consent preferences (opt-in for marketing) are synchronized across all profiles. The administrator is considering adjusting the unification rules. The current matching rules use only email address. What is the best course of action to reduce duplicates while maintaining data accuracy?

Accepted Answer

Add additional matching conditions such as phone number and postal code. Adding additional matching conditions (such as phone number and postal code) increases the precision of duplicate detection. With only email as the match condition, records that share the same email but belong to different individuals (e.g., family accounts) or have data entry errors are incorrectly merged. By requiring multiple identifiers to match, the system reduces false positives while still catching true duplicates, improving the overall accuracy of the unified customer profiles.

Answer

Create separate unifications for each region

Answer

Remove the email condition and use only customer name

Answer

Lower the match confidence threshold to 50% to match more records

Question 20

Adventure Works Cycles uses Dynamics 365 Customer Insights to analyze customer behavior. They have ingested data from their online store, including browsing history, cart additions, and purchases. They want to create a segment of customers who have added items to the cart but not purchased in the last 7 days (abandoned cart). The data includes a 'CartAdd' table with fields: CustomerID, ProductID, Timestamp, and a 'Purchase' table with fields: CustomerID, ProductID, Timestamp, Amount. The segment is created with condition: CartAdd.Timestamp > 7 days ago AND NOT EXISTS (Purchase where CustomerID matches and ProductID matches and Purchase.Timestamp > CartAdd.Timestamp). However, the segment returns no members. What is the most likely reason?

Accepted Answer

The timestamp condition is reversed; it should be CartAdd.Timestamp < 7 days ago to find older carts. The condition `CartAdd.Timestamp > 7 days ago` selects records where the cart addition occurred **less than** 7 days ago (i.e., within the last 7 days). To find customers who added items to the cart more than 7 days ago without purchase, the condition should be `CartAdd.Timestamp < 7 days ago` (older than 7 days). The segment returns no members because it is looking for recent cart additions instead of older ones. The `NOT EXISTS` subquery logic is actually correct for abandoned carts (checking that no purchase occurred after the cart addition), but the primary issue is the reversed timestamp comparison.

Answer

The segment requires a relationship between tables that is not defined

Answer

The 'NOT EXISTS' clause is not supported in Customer Insights segments

Answer

The Purchase table does not have the correct data
