The Reliability Coordinator shall test its primary Control Center data exchange capabilities specified in Requirement R2 for redundant functionality at least once every _____.

• A. 30 calendar days
• B. 90 calendar days
• C. 180 calendar days
• D. 1 calendar year

Answer: (B)

Regular verification of the backup data exchange path is essential to keep control center operations reliable. The test ensures that if the primary data exchange channel fails, the redundant path can carry the same real-time data without loss or unacceptable delay, preserving situational awareness and command ability. Testing this redundant capability at least every 90 calendar days keeps the backup path current and functional without overburdening operations. A quarterly cadence strikes a balance: it catches degradations or misconfigurations early while allowing time for fixes and maintenance between tests. If the test were done more frequently, it could become a burden without proportionally increasing reliability; if done less often, hidden failures might go undetected long enough to impact operations. Therefore, the recommended interval is every 90 calendar days.
