A system has the ability to automatically provision additional virtual servers in response to a load increase. This is an example of which of the following cloud features?

Replication duplicates VMs or data to separate locations for redundancy and disaster recovery purposes, not to add capacity in response to real-time load increases.

Resource pooling aggregates physical resources such as CPU, RAM, and storage into shared pools available for allocation, but does not itself describe the automated provisioning of new virtual servers based on demand.

Orchestration refers to the automated coordination of multi-step workflows and service deployments across systems, but does not specifically describe the cloud capability of automatically scaling virtual server instances in response to a load increase.

A virtual network provides the software-defined networking layer that allows new virtual servers to be instantly provisioned and integrated into the environment when load increases, without requiring physical hardware changes. The virtual network abstraction is what enables cloud platforms to spin up additional VMs on demand and connect them seamlessly to existing workloads. This on-demand provisioning capability - backed by virtual networking - is a foundational cloud feature that distinguishes cloud infrastructure from traditional static deployments.
