Quick Answer
The answer is the Data Ingestion API. This feature is correct because it enables near real-time data ingestion into Dynamics 365 Customer Insights by allowing external systems, such as a retail POS system, to push transaction data immediately via API calls, triggering instant updates to unified customer profiles rather than waiting for scheduled batch imports. On the Microsoft Dynamics 365 Fundamentals CRM MB-910 exam, this question tests your understanding of how Customer Insights handles real-time versus batch data flows, often appearing as a scenario where a company needs immediate profile updates after a customer action. A common trap is confusing the Data Ingestion API with scheduled data sources or connectors, which operate on a delay. Remember the memory tip: “API for instant, batch for later”—if the scenario demands speed, the API is the tool for near real-time data ingestion.
This MB-910 practice question tests your understanding of describe dynamics 365 customer insights. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 retail company uses Dynamics 365 Customer Insights to unify customer data from multiple sources. They want to ensure that customer profiles are updated in near real-time when a purchase is made in their POS system. Which feature should they configure?

Correct answer & explanation
Data Ingestion API
The Data Ingestion API allows real-time or near real-time data ingestion into Dynamics 365 Customer Insights. When a purchase occurs in the POS system, the API can be called immediately to push that transaction data, triggering an update to the unified customer profile without waiting for a scheduled batch import.
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 scheduled, batch-oriented Data Sources Connector (Option C) with the real-time Data Ingestion API, assuming any connector can achieve near real-time updates, but only the API supports event-driven, low-latency ingestion.
Detailed technical explanation
The Data Ingestion API uses RESTful endpoints (e.g., POST to /api/v1/ingest/{dataSourceName}) to push data directly into Customer Insights. Each call can include a single record or a batch, and the system processes it within seconds, updating the unified profile if the entity matches an existing customer identifier (e.g., email or loyalty ID). This is critical for scenarios like fraud detection or personalized offers at the point of sale, where latency must be under a few seconds.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
