Which of the following would be MOST appropriate if an organization’s requirements mandate complete
control over the data and applications stored in the cloud?

A.
Hybrid cloud

B.
Community cloud

C.
Private cloud

D.
Public cloud

Explanation:
A private cloud is a cloud service for internal use only and is located within a corporate network rather
than on the Internet. It is usually owned, managed, and operated by the company, which gives the
company full control over the data and applications stored in the cloud.
Incorrect Answers:
A: A hybrid cloud is a mixture of private and public cloud components. In a private cloud the company
would have control over the data and applications in the cloud but not on the private cloud where they
will only have control over their own data.
B: A community cloud is a cloud environment maintained, used, and paid for by a group of users or
organizations for their shared benefit, such as collaboration and data exchange. This may allow for some
cost savings versus accessing private or public clouds independently.D: A public cloud is a cloud service that is accessible to the general public, typically over an Internet
connection. It services usually requires some form of subscription or payment. Consumers only have
control over their own data on the cloud.
