Final answer:
A) Public Cloud is the most appropriate answer.
Step-by-step explanation:
The given situation where a company uses cloud service to host DNS & DHCP servers is an example of a private cloud environment. In a private cloud, the cloud infrastructure is dedicated to a single organization and is not shared with other users. This ensures that the organization has complete control over the servers and data stored in them.
When a company uses a cloud service to host DNS & DHCP servers, this scenario is most commonly associated with a Public Cloud environment. In a Public Cloud setting, cloud services are provided over the internet and are shared amongst multiple organizations or clients. This form of cloud computing is often chosen for its scalability, cost-effectiveness, and ease of access. In contrast, a Private Cloud is exclusive to one organization, a Hybrid Cloud combines private and public clouds, and a Community Cloud is shared by organizations with common goals or requirements. Since the question does not specify exclusive use, shared resources, or a mix of environments, option A) Public Cloud is the most appropriate answer.
