A startup is unsure how many customers it will attract and does not want to buy a large fleet of servers before launch. Which benefit of the AWS Cloud most directly addresses this concern?
- AIt lets the firm trade a large upfront capital expense for a variable expense tied to usage Correct
- BIt guarantees that every workload will run faster than on the firm's own hardware
- CIt removes the need to apply any security controls because AWS handles all of them
- DIt provides a single fixed monthly price that never changes regardless of how much is used
Why A is correct: Paying only for the capacity actually used removes the need to buy servers in advance, which is exactly what a startup with uncertain demand wants.
Why B is wrong: AWS does not promise universally faster performance, and raw speed is not the concern here; the startup is worried about committing to hardware it may not need.
Why C is wrong: AWS uses a shared responsibility model and does not handle all security, so this misstates how the cloud works and does not address the hardware concern.
Why D is wrong: Cloud pricing usually scales with consumption rather than a flat fee, so the idea of an unchanging fixed bill is the opposite of the variable expense benefit.
