c) CostDATACENTER = 1nΣ(UnitCostDATACENTER x (Revenue +(CostDATACENTER/Utilization))SYSTEMn
d) All of the mentioned
View Answer
Explanation: Sum includes terms for System 1, System 2, System 3, and so on.
5. Point out the wrong statement.
a) Data center operates under average loads
b) Private cloud doesn’t pooling of resources that a cloud computing provider can achieve
