A healthcare provider keeps sensitive data on-premises but uses Azure services for extra capacity during peak periods. Which deployment model describes this setup?

Hybrid cloud is the correct answer because it describes an environment that combines on-premises infrastructure (where the sensitive data is kept) with public cloud services (Azure, used for extra capacity). This allows organizations to leverage the benefits of both, such as maintaining control over sensitive data while gaining scalability and flexibility from the cloud. Private cloud refers to cloud computing resources used exclusively by one organization, typically on-premises or hosted by a third party. Multi-cloud involves using multiple public cloud providers, but doesn't necessarily include on-premises infrastructure. Public cloud refers to cloud services offered over the public internet by a third-party provider, without any on-premises component.
