Each entity shall notify entities identified in Requirements R1, R3, and R5 within _____ of the detection of a failure of its Interpersonal Communication capability that lasts 30 minutes or longer.

Each entity shall notify entities identified in Requirements R1, R3, and R5 within _____ of the detection of a failure of its Interpersonal Communication capability that lasts 30 minutes or longer.

• A. 60 minutes
• B. 30 minutes
• C. 2 hours
• D. 90 minutes

Answer: (A)

The key idea is that once the Interpersonal Communication capability is detected to have failed for 30 minutes or longer, designated entities must be notified within a one-hour window. The 30-minute mark is the threshold that makes the outage reportable, but the deadline is the one-hour limit from detection to alert the identified parties in R1, R3, and R5. This balances timely awareness with a realistic amount of time to gather basic information and notify stakeholders. Why this fits best: the requirement emphasizes a prompt, but not instantaneous, notification after detecting a meaningful disruption. Notifying within 30 minutes would be stricter than specified and could be unrealistic for gathering necessary details, while reporting within 2 hours or 90 minutes goes beyond the mandated one-hour deadline.
