Question 5

Which of the following is a key advantage of the public cloud model for a startup company with limited capital?

Accepted Answer

No upfront capital investment — pay only for resources used. For a startup with limited capital, the public cloud model eliminates the need for large upfront hardware purchases. Instead, it uses a consumption-based pricing model where you pay only for the compute, storage, and network resources you actually use, typically billed per second or per hour. This operational expenditure (OpEx) model directly addresses the capital expenditure (CapEx) constraints of a new company.

Answer

Complete control over all hardware configurations

Question 7

Which cloud computing characteristic allows an organization to avoid purchasing excess capacity to handle occasional peak loads?

Accepted Answer

Elasticity. Elasticity is the cloud computing characteristic that allows resources to automatically scale up to meet peak demand and scale down when demand decreases, so organizations only pay for what they use and avoid over-provisioning. This eliminates the need to purchase and maintain excess capacity for occasional load spikes, as the cloud provider dynamically allocates resources in real time.
