Option B, the Disaster Recovery Plan (DRP), is the most useful document when trying to restore IT infrastructure operations after a non-planned interruption. A disaster recovery plan outlines the steps that an organization needs to take to recover its IT infrastructure in the event of a disaster, such as a natural disaster or cyber attack. The goal of a DRP is to minimize the downtime and data loss that may occur due to an unexpected disruption.
A disaster recovery plan typically includes information on the critical systems and applications that are needed to maintain business operations, the backup and recovery procedures for these systems, and the roles and responsibilities of the staff involved in the recovery process. The plan should also specify the recovery time objective (RTO) and the recovery point objective (RPO) for each system, which define the maximum acceptable downtime and data loss respectively.
Service-level agreements (SLAs) are agreements between an organization and its service providers that define the level of service that is expected. While SLAs may include provisions for disaster recovery, they are not as comprehensive as a disaster recovery plan.
A business impact analysis (BIA) is a process that identifies the critical business processes and the impact that an interruption of these processes would have on the organization. The results of a BIA can be used to prioritize recovery efforts and to develop a disaster recovery plan.
A business continuity plan (BCP) is a broader document that outlines the steps that an organization needs to take to continue its operations in the event of a disruption, whether due to a disaster or another type of interruption. A BCP includes information on business processes, staff responsibilities, communication procedures, and more. While a BCP may include provisions for IT infrastructure recovery, it is not as focused on this aspect as a disaster recovery plan.
In summary, a disaster recovery plan is the most useful document when trying to restore IT infrastructure operations after a non-planned interruption, as it provides a comprehensive set of procedures for recovering critical systems and applications.
