ITPEC FE Subject A April 2025 Question 48

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.
