Sample question


A real practice question — this is what every question looks like.

Cloud Concepts

A startup currently spends heavily upfront on physical servers before they are needed. Which AWS cloud economics benefit most directly addresses this?
Elasticity
Trade capital expense for variable expense
Global infrastructure
Managed services

Correct.

AWS lets you pay only for what you use instead of buying hardware upfront.

This is the "trade CapEx for OpEx" principle — instead of large upfront capital investment in data centers and servers, you pay AWS operating expenses based on actual usage. Elasticity is related but describes scaling up/down, not the financial shift itself.
