Which statement is true regarding pricing for these eight instances?
The eight instances will be charged as regular instances.
Four instances will be charged as RIs, and four will be charged as regular instances.
Five instances will be charged as RIs, and three will be charged as regular instances.
The eight instances will be charged as RIs.
Explanations:
The eight instances will not be charged as regular instances because Account A has purchased five Reserved Instances (RIs) that can be applied to its instances.
This option suggests that four instances will be charged as RIs, which is impossible since Account A only has five RIs. Account B has no RIs and thus its instances will be charged as regular instances.
Account A has five RIs available, which can cover its four running instances. Therefore, three instances from Account B will be charged as regular instances, resulting in a total of five RIs applied and three regular instances.
Not all eight instances can be charged as RIs. Only the four instances in Account A can use the five RIs, while the four instances in Account B will be charged at the regular rate.
As far as I’m aware, the answer is:
Five instances will be charged as RIs, and three will be charged as regular instances.
