Which of the following virtualization technologies can save time during provisioning?

Cloning a virtual machine involves creating an exact copy of an existing, pre-configured VM image or template. This saves considerable time during provisioning because the new VM is immediately ready for use after minor configuration adjustments, bypassing the need for a full operating system and application installation from scratch.

Snapshots capture the state of a virtual machine at a specific point in time, primarily used for backup, testing, or temporary state preservation, not for initial provisioning of new, independent virtual machines.

Clustering aggregates multiple physical servers to provide high availability and load balancing for VMs, enhancing reliability and performance, but it does not directly speed up the initial creation or deployment of individual virtual machines.

Virtual memory is a memory management technique that allows an operating system to compensate for physical memory shortages by using disk space as an extension of RAM, which is a core OS function and not a virtualization technology for provisioning.
