To prevent a virtual machine from taking a snapshot of the disk and ensure all data is permanently written, which mode should be selected?

Selecting the Independence-durable mode is correct for preventing a virtual machine from taking snapshots of the disk and ensuring that all data is permanently written. This mode allows the virtual machine to be independent of any underlying snapshots, meaning that any changes made during the session are not saved to the disk when the virtual machine is powered off or reset.

In this mode, data is written directly to the virtual disk and is not impacted by snapshot functionalities. This is particularly useful in scenarios where you want to maintain a clean state while ensuring that any changes within a session do not persist after shutdown, thereby writing all updates to the disk immediately and permanently.

Options that suggest non-persistence or merely independence do not fulfill the requirement to ensure data permanence, as they still allow for transient states where data could be lost or where snapshots could occur. By ensuring the virtual machine operates in a durable mode, users can confidently work with data, knowing it is securely written without the risk of snapshot-induced changes.
