Why each option
A virtual machine snapshot captures the state and data of a VM at a specific moment, allowing it to be reverted to that exact point in time.
A snapshot is not a backup copy; it is a point-in-time state that relies on the original virtual disk and is typically not stored independently for long-term recovery.
A virtual machine snapshot is a revertible point in time that includes the VM's state (running, paused, or off), data (disks), and configuration, allowing administrators to restore the VM to that specific moment. This is particularly useful for applying updates, testing new software, or recovering from unexpected issues without performing a full restore from a backup.
An exact copy implies a duplicate VM, which is different from a snapshot that records a state difference from the original base disk.
An image of a virtual machine is typically a template used for provisioning new VMs, whereas a snapshot is tied to a specific running VM for rollback purposes.
