Correct answer & explanation
✓
Use Amazon Forecast with the DeepAR+ algorithm and provide item metadata, holiday calendars, and promotion data
Amazon Forecast is purpose-built for time-series forecasting and automatically handles multiple SKUs, holidays, and promotions. SageMaker would require building custom models from scratch. Comprehend is NLP, and QuickSight is for visualization.
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 Amazon Comprehend to analyze customer reviews and correlate with sales
Why it's wrong here
Comprehend is for NLP, not time-series forecasting.
- ✗
Upload data to Amazon QuickSight and use its built-in forecasting widget
Why it's wrong here
QuickSight's forecasting is limited for many SKUs and lacks advanced features.
- ✓
Use Amazon Forecast with the DeepAR+ algorithm and provide item metadata, holiday calendars, and promotion data
Why this is correct
Forecast is designed for scalable, accurate forecasting with built-in handling of external regressors.
- ✗
Train individual ARIMA models for each SKU using Amazon SageMaker built-in algorithms
Why it's wrong here
Manual per-SKU modeling is labor-intensive and ARIMA may not capture external factors well.
