A. B. C. D.A.
Recovery time objective (RTO) is the length of time from the moment of an interruption until the time the process must be functioning at a service level sufficient to limit financial and operational impacts to an acceptable level.
Maximum tolerable outage (MTO) is the maximum time for which an organization can operate in a reduced mode.
Recovery point objectives (RPOs) relate to the age of the data required for recovery.
Services delivery objectives (SDOs) are the levels of service required in reduced mode.
To determine the target for restoration of normal processing, a security manager would establish the Recover Time Objective (RTO).
RTO is the maximum acceptable length of time that a system, application, or business process can be offline or unavailable due to an unexpected disruption or disaster. It is a critical component of a business continuity plan, and it helps organizations to define the minimum level of service they need to maintain during an outage.
The RTO is typically determined by the business impact analysis, which helps identify critical business processes, systems, and data that need to be restored in the event of an outage. The RTO is then set based on the recovery time required for each critical component, taking into account the impact on business operations, customer satisfaction, and regulatory requirements.
The Maximum Tolerable Outage (MTO) is the maximum amount of time that a system or process can be down before the organization incurs unacceptable losses. It is often used as a basis for determining the RTO, but it is not the same thing. The MTO is typically determined by the business impact analysis, and it takes into account the financial and reputational impact of an outage.
The Recovery Point Objective (RPO) is the maximum amount of data that an organization can afford to lose in the event of a disruption or disaster. It is often used in conjunction with the RTO to determine the minimum level of service that needs to be maintained during an outage.
The Service Delivery Objective (SDO) is a performance metric that measures the level of service that an organization provides to its customers. It is not directly related to determining the target for restoration of normal processing.
Therefore, the correct answer is A. Recover Time Objective (RTO).
