Difficulty: HardBusiness Impact Analysis and Business Continuity Management

An airline's risk management team completes a Business Impact Analysis (BIA) for its automated crew scheduling engine. The BIA establishes that an operational disruption exceeding 8 hours will result in uncontrollable flight cancellations and severe regulatory penalties (Maximum Tolerable Downtime, MTD). After IT infrastructure restoration, technical staff require exactly 2 hours to perform database integrity checks and operational verification before handing the system back to operations (Work Recovery Time, WRT). Additionally, the business permits a maximum data loss window of 30 minutes of transaction logs. Which of the following represents the maximum Recovery Time Objective (RTO) that the IT recovery team must target to ensure compliance with the BIA?

  1. 6 hoursAnswer
  2. B
    30 minutes
  3. C
    8 hours
  4. D
    10 hours

Answer

6 hours
The Recovery Time Objective (RTO) represents the maximum allowable duration for restoring technical systems and applications. To prevent total outage duration from exceeding the Maximum Tolerable Downtime (MTD) of 8 hours, the RTO must accommodate the mandatory 2-hour Work Recovery Time (WRT) required for data verification and operational testing. Calculating RTO=MTD−WRT\text{RTO} = \text{MTD} - \text{WRT} gives 8 hours−2 hours=6 hours8\text{ hours} - 2\text{ hours} = 6\text{ hours}.

Step-by-Step Solution

1
Extract the Business Impact Analysis (BIA) metric parameters from the scenario.
Maximum Tolerable Downtime (MTD) = 8 hours; Work Recovery Time (WRT) = 2 hours; Recovery Point Objective (RPO) = 30 minutes.
Categorizing the specific continuity constraints is necessary before calculating target restoration metrics.
2
Apply the business continuity relationship equation: MTD=RTO+WRT\text{MTD} = \text{RTO} + \text{WRT}.
RTO=MTD−WRT=8 hours−2 hours=6 hours\text{RTO} = \text{MTD} - \text{WRT} = 8\text{ hours} - 2\text{ hours} = 6\text{ hours}.
Technical infrastructure recovery (RTO) combined with post-recovery business validation (WRT) must fit within the maximum allowable outage window (MTD).
