Zorluk: OrtaBusiness Continuity and Disaster Recovery

An enterprise network operations team is establishing key performance indicators (KPIs) for a mission-critical payment gateway system. The Business Impact Analysis (BIA) specifies that data loss during a unexpected outage must not exceed 30 minutes of transaction history, and full operational capability of the network infrastructure must be restored within 2 hours of a disruption. Which TWO of the following configuration goals or metrics directly align with these specified business requirements? (Select TWO.)

  1. Establishing a Recovery Point Objective (RPO) target of 30 minutes or lessCevap
  2. Establishing a Recovery Time Objective (RTO) target of 2 hours or lessCevap
  3. C
    Setting a Mean Time Between Failures (MTBF) threshold of 2 hours
  4. D
    Provisioning a cold disaster recovery site to meet the 2-hour operational restoration target
  5. E
    Executing daily differential backups every 24 hours as the sole data protection policy

Cevap

The correct strategies are establishing a Recovery Point Objective (RPO) target of 30 minutes or less and establishing a Recovery Time Objective (RTO) target of 2 hours or less.
Establishing an RPO of 30 minutes directly satisfies the constraint that data loss must not exceed 30 minutes of transaction history. Establishing an RTO of 2 hours directly satisfies the requirement that network capability must be restored within a 2-hour timeframe.

Adım Adım Çözüm

1
Evaluate the maximum tolerable data loss parameter.
The requirement bounds data loss to no more than 30 minutes of transactions.
Recovery Point Objective (RPO) measures the maximum acceptable age of data that can be lost from a system failure.
2
Evaluate the maximum tolerable downtime parameter.
The requirement specifies complete service restoration within 2 hours.
Recovery Time Objective (RTO) defines the targeted duration of time within which a network or system must be restored to service.
3
Analyze distractor strategies against recovery metrics.
MTBF measures component reliability, cold sites require long deployment lead times, and 24-hour backup cycles allow excessive data loss.
Downtime recovery speed is incompatible with unprovisioned cold sites, and MTBF is a measure of uptime frequency rather than recovery performance.
