MS-900 Describe cloud concepts Practice Question
Which cloud deployment model exclusively uses resources that are owned and managed by a single organization, and is often chosen for its high level of control and compliance?
⚠ Common exam trap
Candidates often confuse 'private cloud' with 'on-premises infrastructure' and may incorrectly select 'hybrid cloud' thinking it offers the same control, but the question specifically asks for a model that exclusively uses resources owned by a single organization, which is the defining characteristic of a private cloud.

Correct answer & explanation
✓
Private cloud
The private cloud deployment model is correct because it is defined as a cloud infrastructure that is provisioned for exclusive use by a single organization. This model provides the highest level of control over data, security, and compliance, as the organization owns and manages the underlying hardware and software, often within its own data center or via a dedicated hosted environment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Public cloud
Why it's wrong here
Public cloud services are offered by third-party providers over the internet using a multi-tenant architecture, where compute, storage, and networking are pooled and shared among many customers. Because the provider owns and operates the infrastructure, an individual organization does not have exclusive use of the underlying physical resources; isolation is logical (e.g., VMs, virtual networks) rather than physical. This directly contradicts the exclusivity requirement, making public cloud incorrect.
- ✓
Private cloud
Why this is correct
A private cloud is provisioned for exclusive use by a single organization and may be managed by the organization itself or by a third party, and may be hosted on-premises or in a provider's data center. The infrastructure—including virtualized servers, storage, and networking—is dedicated to that one tenant, giving the organization full control over resource allocation, security policies, and compliance adherence. This exclusive, single-tenant nature is the defining characteristic that makes private cloud the correct answer.
- ✗
Hybrid cloud
Why it's wrong here
A hybrid cloud is a composition of two or more distinct cloud infrastructures—typically a private cloud and a public cloud—that remain unique entities but are bound together by orchestration or integration to enable workload portability. Because it necessarily includes public cloud components, the overall model does not exclusively use resources dedicated to a single organization; part of the environment is on shared multi-tenant infrastructure even if other workloads remain on private resources. This fails the exclusivity condition, so hybrid is incorrect.
- ✗
Community cloud
Why it's wrong here
A community cloud is a shared infrastructure provisioned for exclusive use by a specific community of consumers from organizations that have common concerns such as compliance, jurisdiction, or security objectives. Although the infrastructure may be dedicated to that community, it is shared among multiple organizations rather than owned or used by a single organization, and governance is distributed across the member organizations. Therefore it does not satisfy the requirement of exclusive use by one organization, making it incorrect.
