Recovery Point Objective (RPO)

B.

The recovery point objective (RPO) is the point in the processing flow at which system recovery should occur.

This is the predetermined state of the application processing and data used to restore the system and to continue the processing flow.

Disaster declaration is independent of this processing checkpoint.

Restoration of the system can occur at a later date, as does the return to normal, after-image processing.

The recovery point objective (RPO) is a key metric used in disaster recovery planning to determine the maximum acceptable amount of data loss in the event of a disruption. It represents the point in time to which data must be restored after an incident in order to meet business requirements.

Out of the options provided, the answer that best describes the recovery point objective (RPO) is B. Before-image restoration. Before-image restoration refers to the process of restoring data to a previous point in time, typically using a backup or snapshot taken prior to the disruption. This is necessary in order to meet the RPO, which specifies the maximum acceptable amount of data loss.

Disaster declaration (option A) refers to the process of formally acknowledging that a disaster has occurred and activating the associated disaster recovery plan. While this may be a necessary step in some cases, it is not directly related to the RPO.

System restoration (option C) refers to the process of restoring an entire system or application to a working state. While this may be necessary in order to meet the RPO, it is not the same as the RPO itself.

After-image processing (option D) refers to the process of analyzing data that has been written to a system after a disruption has occurred. While this may be useful for forensic purposes, it is not directly related to the RPO.

In summary, the recovery point objective (RPO) requires before-image restoration in order to meet the maximum acceptable amount of data loss specified by the RPO.
