A Snapshot is a point-in-time copy of a virtual machine’s state, including its data, configuration, and memory, taken at regular intervals. It allows Phil to revert to the last saved version after a crash, preserving the VM’s architecture. This is common in virtualization platforms like VMware or Hyper-V.

Option B (Mirroring):Duplicates data in real time, not a point-in-time backup.

Option C (CDP):Captures every change continuously, more granular than needed here.

Option D (D2D):Transfers data between disks, not specific to VM state capture.

“Snapshots provide point-in-time backups of virtual machines, capturing their full state for quick recovery, ideal for experimental or critical workloads” (Module: Virtualization and Recovery, Section: VM Backup Methods).
