Difficulty: EasyBusiness Impact Analysis and Business Continuity Management

A healthcare organization specifies that its critical Electronic Health Record (EHR) database cannot be offline for longer than four hours in total before severe operational disruption and patient care risks occur. Which of the following business continuity metrics represents this total maximum allowable outage timeframe?

  1. Maximum Tolerable Downtime (MTD)Answer
  2. B
    Recovery Point Objective (RPO)
  3. C
    Mean Time Between Failures (MTBF)
  4. D
    Mean Time to Repair (MTTR)

Answer

Maximum Tolerable Downtime (MTD)
Maximum Tolerable Downtime (MTD) represents the absolute upper limit of time a business function or IT system can be down before the enterprise suffers unacceptable or irreversible operational damage.

Step-by-Step Solution

1
Identify the key requirement in the scenario
The organization needs to define the absolute maximum threshold of time a system can be down before catastrophic impact occurs (4 hours).
Business Impact Analysis establishes upper boundaries for allowable downtime to protect essential functions.
2
Map the requirement to the appropriate BIA metric
Maximum Tolerable Downtime (MTD) is the metric defining the maximum threshold of overall outage time.
MTD represents the maximum outage time an enterprise can survive before experiencing fatal disruption.
