AWS Certified Cloud Practitioner — Question 16

Which cloud computing benefit does AWS demonstrate with its ability to offer lower variable costs as a result of high purchase volumes?

Answer options

• A. Pay-as-you-go pricing
• B. High availability
• C. Global reach
• D. Economies of scale

Correct answer: D

Explanation

The correct answer is 'Economies of scale' since AWS can leverage its large volume of sales to reduce costs, benefiting customers. 'Pay-as-you-go pricing' refers to billing based on usage, while 'High availability' and 'Global reach' describe different aspects of AWS's service offerings, not cost reduction.
