Selected Answer: B
A snapshot is a feature in hypervisors that captures the state of a virtual machine (VM) at a specific point in time. This includes the VM's configuration, memory, and virtual disk data. Snapshots can be used to restore a VM to a previous version, allowing administrators to revert the VM to a known good state in case of problems, such as failed updates, configuration changes, or application issues.

Selected Answer: B
Answer is B. The one of the differences between a storage snapshot and a backup is that the snapshot is stored at the same location as the original data. Therefore, it depends entirely on the reliability of the source. This means that in case of a disaster or damage to the source data, the storage snapshot will be lost or inaccessible. There is no way to restore if the source gets lost. In addition, snapshots on their own do not have the means to check for corruption or restore capabilities.

Hyper-V snapshots are not a backup alternative The most important thing that you should know about Hyper-V snapshots is that they are not backups and cannot provide the same level of data protection as backup software. VM snapshots are merely a short-term solution for saving the VM state at a particular point in time but it doesn’t actually create a copy of the virtual disk. Hyper-V snapshots cannot protect against issues that might affect the host. If the VM gets damaged, created snapshots will be deleted as a result. Thus, the main virtual disk remains a single point of failure in your environment.
