Zorluk: OrtaBusiness 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 hoursCevap
  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

Cevap

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.

Adım Adım Çözüm

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.
