When a DR Vault Server becomes an active vault, it will automatically fail back to the original state once the Primary Vault comes back online.
A DR Vault Server will automatically fail back to the original state once the Primary Vault comes back online only if the AllowFailback setting is set to yes in the padr.ini file. Without this specific setting, automatic failback does not occur. Hence, the correct answer is that it is true only under this condition.
