Same question on ITPEC: Apr 2025 Q48

Which of the following is an explanation of a hybrid cloud?

a)To configure and provide the service content of a cloud service for both consumers and companiesb)To customize some of the functions that are provided by a cloud service for the company’s own usec)To provide an environment where data and application software are linked and interoperable between a cloud service for the exclusive use of a company and a general-purpose cloud serviced)To separately provide the service content of a cloud service as paid services and free services

Explanation

A private cloud and a public cloud linked so that data and applications interoperate — that combination is a hybrid cloud.

Cloud deployment models differ in who uses the infrastructure:

•Private cloud: for the exclusive use of one company
•Public cloud: a general-purpose service shared by many users
•Hybrid cloud: two or more of these connected, so data and applications can move or work across them

A company can keep sensitive systems in its private cloud and use the public cloud for peaks or less critical work.

Answer (c)

Why not others:

•(a) — offering one service to both consumers and businesses is a question of target market, not of how clouds are combined
•(b) — customizing some functions of a cloud service for one's own use is tailoring a single service, not linking two clouds
•(d) — offering paid and free tiers is a pricing model (freemium), not a deployment model

Key rule: Deployment models (public, private, community, hybrid) describe who shares the infrastructure; hybrid means different models joined and interoperable.
