Which cloud model involves infrastructure shared between several organizations from a specific community with common concerns?

• A. Public cloud
• B. Private cloud
• C. Hybrid cloud
• D. Community cloud

Answer: (D)

Community cloud models involve infrastructure shared by a defined group of organizations that have common concerns, such as security, compliance, or governance needs. This setup lets those organizations pool resources and costs while applying uniform policies and controls tailored to their shared requirements. It’s distinct from a public cloud, which serves the general market and is typically multi-tenant; from a private cloud, which is dedicated to a single organization; and from a hybrid cloud, which combines private and public environments. The defining feature here is the defined community with common concerns that justify a shared infrastructure.
