How is a billing period defined in typical cloud billing contexts?

• A. The inclusive start and exclusive end date and time
• B. The start date only
• C. The end date only
• D. Both dates inclusive

Answer: (A)

Billing periods are defined as a time interval where the start moment is included and the end moment is not. This inclusive start / exclusive end convention means you charge for everything from the exact start time up to, but not including, the end time, so consecutive periods fit together without gaps or overlaps. In cloud billing, the end boundary marks when the next period begins, keeping measurements clean and unambiguous. The other options don’t fit because they either miss part of the interval, leave the end unconstrained, or count an endpoint that would cause double counting when periods follow one another.
