Question

Difficulty: MediumBusiness Impact Analysis and Business Continuity Management

A municipal public safety agency completes a Business Impact Analysis (BIA) for its automated emergency computer-aided dispatch system. The analysis determines that the agency can tolerate a maximum data loss of 5 minutes of call records during an unexpected database disruption. Additionally, the overall emergency dispatch service must be restored and operational within 4 hours to prevent severe operational breakdown. Which of the following choices correctly categorizes these two business continuity thresholds?

  1. Recovery Point Objective (RPO) of 5 minutes and Recovery Time Objective (RTO) of 4 hoursAnswer
  2. B
    Recovery Time Objective (RTO) of 5 minutes and Recovery Point Objective (RPO) of 4 hours
  3. C
    Mean Time Between Failures (MTBF) of 5 minutes and Maximum Tolerable Downtime (MTD) of 4 hours
  4. D
    Recovery Point Objective (RPO) of 5 minutes and Mean Time to Repair (MTTR) of 4 hours

Answer

The emergency dispatch system requires a Recovery Point Objective (RPO) of 5 minutes and a Recovery Time Objective (RTO) of 4 hours.
The correct response accurately pairs the 5-minute data loss threshold with the Recovery Point Objective (RPO) and the 4-hour system restoration timeline with the Recovery Time Objective (RTO). RPO focuses on data integrity and transactional loss limits, whereas RTO focuses on service availability and downtime limits.

Step-by-Step Solution

1
Identify the data loss threshold established in the Business Impact Analysis scenario.
The maximum allowable data loss is 5 minutes.
Recovery Point Objective (RPO) defines the maximum tolerable age of unrecovered data resulting from a system disruption.
2
Identify the system restoration time target established in the Business Impact Analysis scenario.
The target duration to restore operational service is 4 hours.
Recovery Time Objective (RTO) defines the maximum acceptable amount of time that a business process can be down after a failure.
3
Map the identified metrics to the corresponding continuity metrics.
RPO = 5 minutes, RTO = 4 hours.
Matching the BIA parameters directly aligns 5 minutes to RPO and 4 hours to RTO.
