Zorluk: ZorBusiness Impact Analysis and Business Continuity Management

A global logistics company completes a Business Impact Analysis (BIA) for its primary automated warehouse dispatch engine. The assessment reveals that to prevent irrecoverable inventory ledger corruption, data loss cannot exceed the last 15 minutes of queued transaction records preceding an outage. Furthermore, management specifies that while distribution centers can briefly operate on manual contingency protocols, the automated system must be fully restored and operational within 6 hours to prevent severe contractual SLA penalties. Which target metric configuration must the lead security architect establish to meet these operational requirements?

  1. A Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 6 hours.Cevap
  2. B
    A Recovery Time Objective (RTO) of 15 minutes and a Recovery Point Objective (RPO) of 6 hours.
  3. C
    A Maximum Tolerable Downtime (MTD) of 15 minutes and a Work Recovery Time (WRT) of 6 hours.
  4. D
    A Mean Time Between Failures (MTBF) of 6 hours and a Mean Time to Repair (MTTR) of 15 minutes.

Cevap

A Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 6 hours.
The option specifying an RPO of 15 minutes and an RTO of 6 hours correctly applies standard Business Impact Analysis parameters. Recovery Point Objective (RPO) designates the maximum tolerable amount of data lost, expressed as a time measurement prior to the incident (15 minutes of transactions). Recovery Time Objective (RTO) designates the maximum allowable targeted duration for restoring IT infrastructure and application functionality (6 hours).

Adım Adım Çözüm

1
Analyze the data loss requirement stated in the scenario.
The scenario allows a maximum data loss timeframe of 15 minutes of transaction logs.
Recovery Point Objective (RPO) dictates the maximum acceptable interval of data loss measured backward from the point of failure.
2
Analyze the system outage duration requirement stated in the scenario.
The system service must be restored within 6 hours of disruption.
Recovery Time Objective (RTO) dictates the maximum acceptable duration of system downtime to restore operations.
3
Map the analyzed parameters to the correct BIA metric definitions.
RPO = 15 minutes; RTO = 6 hours.
Combining RPO (data loss window) and RTO (downtime restoration window) correctly satisfies both continuity constraints.
