Zorluk: OrtaBusiness Impact Analysis and Business Continuity Management

An enterprise security architecture team is defining continuity metrics for a critical containerized payment gateway during a Business Impact Analysis (BIA). Executive leadership establishes that customer transaction records can tolerate a maximum data loss timeframe of 1515 minutes, and the payment gateway system must be fully restored and operational within 22 hours following an uncontained infrastructure failure. Which of the following statements correctly align these operational requirements with business continuity metrics? (Select TWO.)

  1. The Recovery Point Objective (RPO) for transaction data persistence must be established at 15 minutes or less.Cevap
  2. B
    The Recovery Point Objective (RPO) dictates that infrastructure services and application containers must be restored within 2 hours of an outage.
  3. The Recovery Time Objective (RTO) for the payment application system must be set to 2 hours or less.Cevap
  4. D
    Implementing an active-active high-availability database cluster replaces the need for establishing an RPO target or conducting data backups.

Cevap

The statement specifying that the Recovery Point Objective (RPO) must be set to 15 minutes or less, and the statement establishing that the Recovery Time Objective (RTO) must be set to 2 hours or less are both correct.
The parameters outlined in the scenario map directly to standard Business Impact Analysis (BIA) definitions: acceptable data loss timeframe (1515 minutes) defines the Recovery Point Objective (RPO), while acceptable system downtime before restoration (22 hours) defines the Recovery Time Objective (RTO). Both options asserting these mappings accurately reflect business continuity design principles.

Adım Adım Çözüm

1
Analyze the business requirement for maximum allowable data loss
Maximum acceptable data loss timeframe is 1515 minutes, which defines the Recovery Point Objective (RPO).
RPO measures data loss in time units from the point of failure backward to the last valid data point.
2
Analyze the business requirement for system restoration duration
Targeted restoration time is 22 hours, which defines the Recovery Time Objective (RTO).
RTO defines the maximum acceptable duration of service downtime from the point of disruption forward to operational restoration.
3
Evaluate the distractors against continuity planning principles
Distinguishing RTO from RPO confirms that system recovery timing belongs to RTO, and fault tolerance controls (clustering) do not negate the necessity of RPO backup metrics.
High availability maintains service uptime but does not protect against data corruption or remove baseline BIA metrics.

Anahtar Kavram

Recovery Point Objective (RPO) measures acceptable data loss duration, while Recovery Time Objective (RTO) measures acceptable service restoration timeframe.
