In the CompTIA A+ Core 1 (220-1201) exam objectives, cloud deployment models describe how and where computing resources are hosted and who has access to them. A private cloud is defined as a cloud environment that is dedicated to a single organization and may be hosted on-premises within the company’s own data center or in a dedicated external facility. Since the question states that the directory services server is located on premises, it indicates that the organization is hosting and managing its own infrastructure internally. This aligns directly with the definition of a private cloud deployment model.

Directory services—such as Microsoft Active Directory or LDAP-based services—are commonly deployed internally to manage user authentication, authorization, group policies, and resource access within an organization. When these services run on company-owned hardware inside the organization’s network, the infrastructure remains under the organization’s full administrative control, security policies, and management.

The other options do not match this scenario. A public cloud is hosted by third-party providers and shared among multiple customers ☁. A hybrid cloud combines on-premises infrastructure with public cloud services. A community cloud is shared by multiple organizations with similar requirements. Because the system is hosted internally for a single organization, the correct classification is Private Cloud .
