Zorluk: OrtaBusiness Impact Analysis and Business Continuity Management

An enterprise retail logistics company recently completed a Business Impact Analysis (BIA) for its centralized inventory management platform. The assessment established a Recovery Point Objective (RPO) of 3030 minutes, a Recovery Time Objective (RTO) of 44 hours, and a Maximum Tolerable Downtime (MTD) of 1212 hours. Which of the following technical strategies directly support these established metrics? (Select TWO.)

  1. Configuring transaction log shipping and automated database replication at intervals not exceeding 3030 minutes.Cevap
  2. Provisioning a warm recovery site equipped to restore production database operations within 44 hours of a disaster declaration.Cevap
  3. C
    Implementing high-availability automated failover to guarantee system availability stays within a 3030-minute Maximum Tolerable Downtime.
  4. D
    Scheduling full system backups once every 2424 hours to satisfy the Recovery Point Objective.

Cevap

The correct strategies are: configuring transaction log shipping and database replication at intervals under 30 minutes, and provisioning a warm recovery site capable of restoring operations within 4 hours.
The option specifying replication intervals of 30 minutes or less directly ensures that data loss remains within the 30-minute RPO threshold. Furthermore, the option designating a warm site capable of restoring operations within 4 hours satisfies the specified 4-hour RTO and ensures the business remains well under its 12-hour MTD boundary.

Adım Adım Çözüm

1
Analyze the BIA requirements for RPO
Recovery Point Objective (RPO) is set to 30 minutes, meaning maximum acceptable data loss is 30 minutes of transactions.
Technical controls must back up or replicate data at least every 30 minutes to meet RPO.
2
Analyze the BIA requirements for RTO and MTD
Recovery Time Objective (RTO) is 4 hours, and Maximum Tolerable Downtime (MTD) is 12 hours.
Recovery infrastructure must restore system functionality within 4 hours, which safely falls under the 12-hour MTD threshold.
3
Evaluate the proposed operational options against the metrics
Replication intervals under 30 minutes fulfill RPO, while a warm site capable of 4-hour recovery fulfills RTO.
Daily 24-hour backups violate RPO, and labeling 30 minutes as MTD misinterprets the metric.
