A company runs a private cloud environment for its core business operations but extends some workloads to a public cloud provider during peak usage ×. Which cloud deployment model is being used?

A private cloud refers exclusively to cloud services utilized by a single organization, keeping all resources and data on a dedicated infrastructure. In this case, while the company does operate a private cloud, it does not account for the additional public cloud usage during peak times, making this choice incomplete.

Community cloud is a model where multiple organizations share a cloud infrastructure tailored for a specific community with shared concerns, such as security or compliance. This option does not apply to the scenario described, as the company operates its own private cloud and extends to a public cloud, rather than sharing resources with other organizations.

Multicloud refers to the use of multiple cloud computing services from different providers, which can be either private or public. While this term might seem relevant, it does not specifically highlight the integration of private and public clouds for peak usage, making hybrid cloud the more appropriate and precise model in this context.
