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.
Which THREE of the following are prerequisites for using Customer Insights predictive models?
Real-time data streaming
Why wrong: Real-time streaming is not required.
Data types that match the model requirements (e.g., numeric, categorical)
Correct data types are required.
Power BI integration
Why wrong: Power BI is optional.
Historical data with known outcomes
Models need training data with outcomes.
A minimum number of records (e.g., 1000)
Sufficient data is needed for statistical significance.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Data types that match the model requirements (e.g., numeric, categorical)
Option B is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
The trap here is that candidates confuse optional features (like real-time streaming or Power BI) with hard prerequisites, but Microsoft explicitly lists data type matching, historical outcomes, and minimum record count as non-negotiable requirements for model training.
Detailed technical explanation
Under the hood, Customer Insights predictive models use Azure Machine Learning pipelines that enforce strict schema validation at training time; for instance, a churn prediction model expects a binary outcome column (0/1) and numeric features, and any deviation triggers a validation error. A real-world scenario is a retailer using purchase history (numeric amounts) and customer tenure (numeric days) to predict churn—if the tenure column accidentally contains text like '3 years', the model will reject the dataset. This prerequisite prevents silent failures and ensures model reproducibility.
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.
