Question 423 of 753
AI Associate Data for AI Practice Question
Which TWO data preparation steps are required before using Einstein Discovery for sales forecasting? (Choose 2)
⚠ Common exam trap
Salesforce often tests the misconception that manual data preprocessing steps like normalization or one-hot encoding are required, when in fact Einstein Discovery automates these steps, and the key prerequisite is ensuring a proper date/timestamp field exists for time-based analysis.
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
✓
Include a date or timestamp field for time series analysis
Einstein Discovery requires a date or timestamp field to perform time series analysis, which is essential for identifying trends, seasonality, and patterns in historical sales data. Without this field, the model cannot properly order observations or forecast future values based on temporal dependencies.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Convert all text fields to numeric using one-hot encoding
Why it's wrong here
Einstein Discovery can handle categorical data; manual encoding is not required.
- ✗
Remove duplicate records
Why it's wrong here
While good practice, duplicates are not automatically handled but can cause bias; not a strict requirement.
- ✓
Include a date or timestamp field for time series analysis
Why this is correct
For forecasting, a date field is needed to order records.
- ✓
Ensure all predictor fields have no missing values
Why this is correct
Missing values can cause errors during model training.
- ✗
Normalize numeric fields to a 0-1 scale
Why it's wrong here
Normalization is handled internally by the algorithm.
