Which of the following cloud characteristics explains that a cloud provides services to serve multiple clients according to their priority?

The characteristic that describes a cloud service providing resources to multiple clients according to their priority is resource pooling. This concept refers to the cloud infrastructure's ability to serve a large number of customers by dynamically allocating physical and virtual resources according to demand. In this model, resources such as processing power, storage, and memory are pooled together and assigned to various clients as needed. This allocation can be managed based on the clients' priority, allowing for efficient and flexible resource use. By employing multi-tenancy—a feature inherent in resource pooling—cloud providers can deliver tailored services to different users, optimizing the performance and user experience for each individual client.

Measured service relates to the continual monitoring of cloud services, providing clients with metrics about their resource usage but does not explicitly address prioritization among users. Rapid elasticity is focused on the ability to quickly provision and scale resources in response to demand, and broad network access pertains to the accessibility of cloud services over the internet and through various devices. While important cloud characteristics, they do not specifically define how prioritization among multiple clients is managed.
