Difficulty: MediumBusiness Impact Analysis and Business Continuity Management

A global logistics provider completes a Business Impact Analysis (BIA) for its automated shipment tracking service. The assessment determines that the organization can tolerate a maximum data loss of 15 minutes of transactional updates, requires system infrastructure restoration within 2 hours of a outage, and mandates 1 hour of verification and data integrity checks before resuming operations to prevent exceeding the 4-hour Maximum Tolerable Downtime (MTD). Which of the following statements correctly map these operational findings to business continuity metrics? (Select TWO.)

  1. The Recovery Point Objective (RPO) is set to 15 minutes, dictating that database replication or backup intervals must not exceed 15 minutes of transactional data loss.Answer
  2. B
    The Recovery Point Objective (RPO) is established as 2 hours, specifying the target timeframe within which systems and servers must be brought back online.
  3. The Recovery Time Objective (RTO) is 2 hours for core system restoration, which combined with a 1-hour Work Recovery Time (WRT) ensures total downtime remains below the 4-hour MTD threshold.Answer
  4. D
    Implementing an active-passive redundant cluster to achieve the system recovery timeframe functions primarily as a deterrent security control against system failure.

Answer

The correct statements are: (1) The Recovery Point Objective (RPO) is set to 15 minutes, dictating that database replication or backup intervals must not exceed 15 minutes of transactional data loss; and (2) The Recovery Time Objective (RTO) is 2 hours for core system restoration, which combined with a 1-hour Work Recovery Time (WRT) ensures total downtime remains below the 4-hour MTD threshold.
The scenario correctly maps the 15-minute maximum data loss threshold to the Recovery Point Objective (RPO). Additionally, it accurately identifies the 2-hour infrastructure restoration as the Recovery Time Objective (RTO) and the 1-hour verification period as Work Recovery Time (WRT), confirming that their sum (3 hours3\text{ hours}) is within the 4-hour Maximum Tolerable Downtime (MTD).

Step-by-Step Solution

1
Identify the data loss threshold metric from the scenario context.
The scenario specifies a maximum allowable data loss of 15 minutes of transaction updates, which corresponds directly to the Recovery Point Objective (RPO).
RPO defines the age of files or data that must be recovered from backup storage for normal operations to resume after a disaster.
2
Analyze system recovery and verification timeframes relative to RTO, WRT, and MTD.
The system restoration target of 2 hours is the Recovery Time Objective (RTO). The 1-hour verification phase represents Work Recovery Time (WRT). Together (2 hrs RTO+1 hr WRT=3 hrs2\text{ hrs RTO} + 1\text{ hr WRT} = 3\text{ hrs}), they fall safely under the 4-hour Maximum Tolerable Downtime (MTD).
MTD is the maximum period of time business operations can be disrupted. RTO+WRT≤MTD\text{RTO} + \text{WRT} \le \text{MTD} must hold true to prevent severe business impact.
