Question #1385
Which AWS Cloud computing benefit enables companies to reduce their operational expenditures by leveraging shared resource pooling?
Fault tolerance
Economies of scale
Elasticity
Pay-as-you-go pricing
Explanation
The correct answer is B. Economies of scale. AWS's vast infrastructure allows it to achieve lower costs per unit by pooling resources (e.g., servers, storage, networking) across millions of customers. These cost savings are passed on to customers, reducing their operational expenditures (OpEx).
- Why other options are incorrect:
- A. Fault tolerance: Focuses on system resilience, not cost reduction.
- C. Elasticity: Refers to scaling resources dynamically, not shared cost benefits.
- D. Pay-as-you-go pricing: Aligns costs with usage but does not directly address shared resource pooling.
Key Point: Economies of scale are a core AWS benefit where shared infrastructure lowers costs for all users.
Answer
The correct answer is: B
