Which item is included in RI cost breakdown by line item?

• A. Unamortized costs of unused reservation charged centrally in the billing data.
• B. Upfront cancellation penalties for unused reservations.
• C. Amortized cloud resource costs incurred in that month (cost allocated via tags, labels, and accounts).
• D. The ongoing on-demand charge for resources not covered by reservations.

Answer: (C)

Reserved Instances are paid for upfront, and their cost is spread over the term through amortization. In the monthly RI cost breakdown, you record the amortized portion of that upfront payment as a line item, allocated to the specific resources using tags, labels, and accounts so you can see exactly which resources incur RI cost each month. This reflects the ongoing economic cost of the RI during the period, even if the resources weren’t used to their full capacity in that month. Unamortized upfront costs aren’t shown as monthly RI expenses (they’re treated as prepaid/assets rather than a monthly charge). Upfront cancellation penalties aren’t a typical monthly RI line item, and ongoing on-demand charges for resources not covered by reservations are shown separately as on-demand usage, not as the RI amortization.
