Which of the following design factors would an MSP use to build cloud service offerings?

Public is a cloud deployment model describing who owns and operates the infrastructure, not a design factor specific to how an MSP constructs its service offerings.

Community cloud is a deployment model shared among organizations with common concerns such as compliance requirements, and does not describe the structural design of MSP service offerings.

Private cloud is single-tenant by definition, which is the opposite of the shared, scalable model MSPs use to serve multiple customers cost-effectively.

Multitenancy allows a single MSP to serve many clients on shared underlying infrastructure while logically isolating each customer's data and workloads. This design factor directly enables the MSP business model by spreading infrastructure costs across multiple tenants, reducing per-customer overhead. It is the core design consideration that distinguishes managed service offerings from dedicated single-tenant deployments.
