Question #1337
A company aims to optimize its IT spending by eliminating large initial investments in physical infrastructure. Which cloud computing advantage enables this shift from capital expenditures (CapEx) to operational expenditures (OpEx)?
Achieve greater operational resilience
Automatically scale resources based on demand
Leverage AWS's global infrastructure
Replace capital expenses with pay-as-you-go costs
Explanation
Answer D is correct because the pay-as-you-go pricing model in cloud computing directly replaces capital expenditures (CapEx) like physical servers with operational expenses (OpEx), where costs are based on usage. This eliminates large upfront investments.
Why other options are incorrect:
- A: Operational resilience improves uptime but does not directly address financial model shifts.
- B: Auto-scaling optimizes resource usage but focuses on efficiency, not CapEx-to-OpEx transition.
- C: AWS's global infrastructure enables low-latency access but is unrelated to cost structure changes.
Key Point: Pay-as-you-go pricing is the core cloud feature enabling the shift from CapEx to OpEx.
Answer
The correct answer is: D
