Final answer:
Reverting a Hyper-V VM to the last snapshot does not affect the hierarchy tree of snapshots; they remain intact and no snapshots are removed unless done so manually.A) Nothing
Step-by-step explanation:
When a Hyper-V VM is reverted back to the state of the last snapshot, the hierarchy tree of snapshots for that VM remains intact.
This means that the correct answer is A) Nothing. Snapshots after the reverted state still exist and are not affected by the revert process. Reverting simply means that the virtual machine's state is rolled back to the particular snapshot selected, but the snapshots that were taken after that point are not deleted unless explicitly removed by the administrator.
