Which of the following statements correctly describes the role of the pay-per-use monitor mechanism as part of the Elastic Disk Provisioning cloud architecture?
a. The pay-per-use monitor tracks and collects fixed-disk storage allocation data so that the cloud consumer is billed for the fixed amount of storage provisioned, not for what is consumed.
b. The pay-per-use monitor tracks and collects billing-related usage data as it corresponds to the actual amount of storage provisioned and consumed by the cloud consumer.
c. The pay-per-use monitor tracks the cloud consumer’s on-premise storage capacity, so that the cloud provider is notified of the capacity for which it can elastically provision the disks.
d. None of the above. The pay-per-use monitor is not associated with the Elastic Disk Provisioning architecture
Statement (b) is correct because it correctly states the role of the pay-per-use monitor in relation to this architecture.
