Which of the following describes a scenario where there is no backup available?

The correct choice that describes a scenario where there is no backup available is identified as a data gap. A data gap occurs when there is an absence of backup data or recovery points for critical information. This typically means that, in an event of data loss or system failure, the organization lacks the necessary data to restore operations effectively. Without backups, the organization faces significant risk of losing important information, which can have severe consequences in terms of operational continuity and decision-making processes.

In contrast, the other concepts, while related to resource or operational challenges, do not specifically express the absence of backup data. A resource lacking may refer to shortages of physical assets, personnel, or technical resources needed for operation. An operational gap usually points to inefficiencies or deficiencies in processes and workflows, which can affect performance but does not imply missing backup or data. A capability gap denotes a deficiency in the skills or functions required to perform necessary tasks, which also does not directly convey the idea of unavailable backup data. Therefore, the notion of data gap is specifically aligned with the scenario pertaining to the lack of essential backup resources.
