Which two values correctly represent the standard validity durations for CDM and YM respectively?

• A. 4 hrs and 1 hr
• B. 6 hrs and 2 hrs
• C. 8 hrs and 3 hrs
• D. 12 hrs and 4 hrs

Answer: (B)

Understanding how long a status or credential remains valid helps you plan safety checks and mission tempo. The standard pairing is six hours for CDM and two hours for YM. This means CDM status is considered current for about six hours before it should be reassessed, while YM status requires a check roughly every two hours. The longer six-hour window for CDM fits tasks that can be managed with a moderate cadence of updates, whereas the shorter two-hour window for YM reflects scenarios with more frequent changes or higher risk where timely updates are critical. If operations might exceed these windows, you would segment the work and re-verify or reauthorize to keep safety and accuracy intact.
