1. Which of the following is the best technique for forecasting
demand in a highly volatile supply chain environment?
 a) Moving Average
 b) Exponential Smoothing
 c) ARIMA Model
 d) Linear Regression
 Answer: c) ARIMA Model

 Rationale: ARIMA (AutoRegressive Integ Moving
Average) is well-suited for forecasting in volatile environments
because it can model different types of variability and seasonal
effects.
2. Which data visualization tool is most effective for identifying
bottlenecks in a supply chain process?
 a) Pie Chart
 b) Scatter Plot
 c) Sankey Diagram
 d) Histogram
