If the data exchange test is unsuccessful, the Reliability Coordinator shall initiate action within _____ to restore redundant functionality.

• A. 8 hours
• B. 2 hours
• C. 24 hours
• D. 12 hours

Answer: (B)

When a data exchange test fails, keeping real-time data flowing and maintaining situational awareness is urgent. The Reliability Coordinator is expected to start corrective actions quickly to reestablish an alternate data path or backup mechanism and verify its operation. A two-hour window is short enough to prevent prolonged data gaps while giving enough time to diagnose the issue and switch over or rehabilitate the redundant channel. Longer timeframes—such as eight, twelve, or twenty-four hours—would leave critical data exchange degraded for too long, increasing reliability risk. Thus, initiating action within two hours best supports rapid restoration of redundant functionality.
