The correct answer is to use Power Query with a gateway for on-premises SQL and the Salesforce connector for Salesforce. This is because Dynamics 365 Customer Insights relies on Power Query as its native data ingestion engine, which provides a unified interface to connect to diverse sources. For on-premises SQL Server, Power Query requires an on-premises data gateway to securely bridge the connection without exposing the database to the internet, while for cloud-based Salesforce, it uses a dedicated Salesforce connector that authenticates via OAuth. On the MB-910 exam, this question tests your understanding that Customer Insights does not require custom code or third-party ETL tools—Power Query handles both hybrid and cloud sources natively. A common trap is assuming you need separate tools for each source or that an on-premises SQL database can connect directly without a gateway. Memory tip: think “Gateway for ground, Connector for cloud” to remember the two distinct paths.
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 company is planning to implement Dynamics 365 Customer Insights. They have customer data stored in an on-premises SQL Server database and also in Salesforce CRM. They want to unify this data in Customer Insights. Which data ingestion method should they use to bring data from both sources?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Power Query with a gateway for on-premises SQL and the Salesforce connector for Salesforce
Option B is correct because Dynamics 365 Customer Insights uses Power Query as its primary data ingestion engine, which supports both on-premises SQL Server via an on-premises data gateway and cloud-based Salesforce CRM through a dedicated Salesforce connector. This allows the company to unify data from both sources without requiring intermediate storage or third-party tools.
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.
✗
Use Power Query connectors for cloud data only, then use a gateway for on-premises SQL
Why it's wrong here
Power Query supports both cloud and on-premises via gateway.
✓
Use Power Query with a gateway for on-premises SQL and the Salesforce connector for Salesforce
Why this is correct
Both data sources can be ingested using Power Query connectors.
Related concept
Read the scenario before looking for a memorised answer.
✗
Export data from SQL to Azure Blob Storage and then ingest from Blob, and use Salesforce API
Why it's wrong here
Unnecessary intermediate steps.
✗
Use third-party ETL tool to push data into Customer Insights via API
Why it's wrong here
While possible, not the standard recommended method.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think on-premises data requires a separate ingestion method like Azure Blob Storage, not realizing that Power Query with an on-premises data gateway can directly connect to SQL Server, and that the Salesforce connector is a native Power Query connector.
Detailed technical explanation
How to think about this question
Under the hood, Power Query uses M-language queries to transform and load data, and the on-premises data gateway securely transmits data from on-premises SQL Server to the cloud using Azure Service Bus and HTTPS. The Salesforce connector leverages OAuth 2.0 for authentication and the Salesforce REST API to retrieve objects, supporting incremental refreshes to minimize data transfer. In a real-world scenario, using the gateway ensures that on-premises data remains behind the firewall while still being accessible for unification.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
