What Cloud Deployment model consist of a cloud infrastructure provisioned for exclusive use by a single
organization comprising multiple consumers (e.g., business units)? Such deployment model may be owned,
managed, and operated by the organization, a third party, or some Combination of them, and it may exist on or
off premises.

A.
Private Cloud

B.
Public Cloud

C.
Hybrid Cloud

D.
Community Cloud

Explanation:
A Private cloud. The cloud infrastructure is provisioned for exclusive use by a single organization comprising
multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third
party, or some combination of them, and it may exist on or off premises. Other Cloud Deployment Models are:
Community cloud. The cloud infrastructure is provisioned for exclusive use by a specific community of
consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and
compliance considerations). It may be owned, managed, and operated by one or more of the organizations in
the community, a third party, or some combination of them, and it may exist on or off premises. Public cloud.
The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and
operated by a business, academic, or government organization, or some combination of them. It exists on the
premises of the cloud provider. Hybrid cloud. The cloud infrastructure is a composition of two or more distinct
cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by
standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load
balancing between clouds).
