- A
Create separate boolean fields for each value to improve model accuracy.
Why wrong: This is unnecessary and may cause multicollinearity; Einstein handles it automatically.
- B
Remove the field because text fields cannot be used in Einstein Discovery.
Why wrong: Text fields can be used as categorical predictors.
- C
Keep as a text field and let Einstein Discovery handle it as a categorical predictor.
Einstein Discovery automatically treats text fields as categorical predictors.
- D
Convert to numeric values 1, 2, 3 to preserve order.
Why wrong: The values are nominal, not ordinal; numeric conversion would imply ordering.

AI Associate Data for AI Practice Question
This AI Associate practice question tests your understanding of data for ai. 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 data scientist needs to prepare data for Einstein Discovery. The dataset includes a field 'Customer_Status__c' with values 'Active', 'Inactive', and 'Churned'. How should this field be treated?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Keep as a text field and let Einstein Discovery handle it as a categorical predictor.
Option C is correct because Einstein Discovery natively supports text fields as categorical predictors, automatically encoding them for model training. The platform handles string values like 'Active', 'Inactive', and 'Churned' without requiring manual transformation, preserving the semantic meaning and cardinality of the data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
The values are nominal, not ordinal; numeric conversion would imply ordering.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume text fields must be converted to numbers or one-hot encoded for machine learning, but Einstein Discovery abstracts this preprocessing, and manual conversion can introduce ordinal bias or unnecessary complexity.
Detailed technical explanation
How to think about this question
Under the hood, Einstein Discovery uses automated feature engineering that applies target encoding or frequency encoding for high-cardinality categorical fields, and for low-cardinality fields like this one, it may use one-hot encoding internally—but the user does not need to preprocess manually. A subtle behavior is that if the text field contains typos or inconsistent casing (e.g., 'active' vs 'Active'), Einstein Discovery treats them as distinct categories, so data cleaning is still important. In a real-world churn prediction scenario, preserving the original string values allows the platform to detect patterns like 'Churned' being a strong predictor without imposing an artificial numeric order.
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 practitioner preparing for the AI Associate exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
