Exam SY0-501 topic 1 question 784 discussion

B and C are the concepts, but the name of the technology that implements B and C is called Snapshots.

Keywords > guest os, indicating that it is a VM environment, quickly revert > indicating or describing the purpose of a snapshot.

Looks like Snapshot or can also be revert to know state. but wait they are both the same according to CompTIA.... lol which one to pick. I'll go with mobb rules... NON-PERSISTENCE There are various mechanisms for ensuring non-persistence: Snapshot/revert to known state—This is a saved system state that can be reapplied to the instance. Rollback to known configuration—A physical instance might not support snapshots but has an "internal" mechanism for restoring the baseline system configuration, such as Windows System Restore. Live boot media—another option is to use an instance that boots from read-only storage to memory rather than being installed on a local read/write hard disk.

No adequate info in the question, cant decide answer is Snapshot

Shadow Copy is Microsoft backend technology for doing snapshots, but doesn't apply to Hyper-V, which is Microsoft's hypervisor.

Yes, Snapshot. The Hypervisor (the OS that interacts directly with the physical hardware) creates the Virtual Machine (VM). The VM then presents the virtual hardware to the Guest OS which is the OS that runs on the VM. Best practice is to take a backup or snapshot of the VM before making changes in case they don't work, you can revert back to the snapshot before the changes were made.

VM? snap in virtual machine , in workstation C
