Cloud Service A requires access to Cloud Storage Device A and Cloud Storage Device B.
Cloud Service A is hosted by Virtual Server A.
Virtual Server A and Virtual Server B are hosted by Hypervisor A, which resides on Physical Server A.
Cloud Service Consumer A sends a request to access Cloud Service A (1). Cloud Service A retrieves data from Cloud Storage Device A and Cloud Storage Device B (2). Cloud Consumer A uses the usage and administration portal to access resource usage reports for Cloud Service A (3).
Cloud Service Consumer A and Cloud Consumer A belong to Organization A, which is leasing an laaS environment from the cloud provider.
The cloud provider makes Cloud Service A available to several new cloud service consumers. Additionally, new LUNs are created on Cloud Storage Devices A and B for new cloud consumers to perform regular data access functions. This increase in workload causes Virtual Server A to fail during peak usage periods. Organization A and the new cloud consumer organizations request that the cloud provider find a way to dynamically support the higher usage workloads.
Organization A keeps its master files and data in LUN B in Cloud Storage Device B.
One day, a cloud resource administrator accidentally changes the path used to access LUN B.
The original path cannot be retrieved. The cloud resource administrator informs Organization A's IT department that it must change any systems or tools it uses to access LUN B to the new path. This causes significant challenges, as well as a costly period of disruption. Organization A asks the cloud provider to create a system that would help avoid disruption in access to LUN B, if this was to ever happen again.
The cloud provider has made Cloud Storage Device A part of a resource pool of synchronized cloud storage devices. Organization A is sharing Cloud Storage Device A with another cloud consumer organization. When cloud consumers from both organizations access Cloud Storage Device A at the same time, they encounter a resource constraint condition that causes Cloud Storage Device A to fail. Organization A requests that the cloud provider extend the existing cloud architecture to prevent this situation from happening again.
Which of the following statements provides a solution that can address all of these problems?

정답: A
Cloud Service A is hosted by Virtual Server A, which is hosted by Hypervisor A that resides on Physical Server A.
Cloud Storage Device A is used to store media library data that is continuously replicated with a redundant, secondary implementation of Cloud Storage A (not shown). Access to Cloud Service A is monitored by Pay-Per-Use Monitor A.
Access to Cloud Storage Device A is monitored by Pay-Per-Use Monitor B.
Pay-Per-Use Monitors A and B capture billing-related usage data that is forwarded to a billing management system that is hosted by Physical Server B.
Cloud Service Consumer A accesses Cloud Service A and the usage data is captured by Pay-Per-Use Monitor A (1). Cloud Consumer B accesses Cloud Storage Device A via a usage and administration portal that it uses to upload media data (2). This usage is captured by Pay-Per-Use Monitor B (3). Pay-Per-Use Monitors A and B store collected usage data in the billing management system (4), which is later used by the cloud provider to bill for the usage of Cloud Service A and Cloud Storage Device A.
Each service instance of Cloud Service A requires a virtual server with 2 virtual CPUs and
4 GBs of RAM at a package price of $2.00 for each initial invocation and an additional
$0.50 for each consecutive 60 seconds of usage. Cloud Service Consumer A accesses Cloud Service A twice in one day. The two exchanges with Cloud Service A last 60 seconds and 120 seconds. For that one day, the organization that owns Cloud Service Consumer A is billed $6.50, which it determines is incorrect. After complaining to the cloud provider, it is discovered that the rapid provisioning system responsible for provisioning instances of Cloud Service A is not de-provisioning Cloud Service A when Cloud Service Consumer A indicates it has completed an exchange. Instead, Cloud Service A is de- provisioned after a 60 second timeout that occurs after Cloud Service Consumer A is completed with an exchange.
Storage space on Cloud Storage Device A can only be purchased in units of terabytes (TBs), with each TB costing $1 per day. Cloud Consumer B purchases 5 TBs of storage space on day 1 and stores 5 TBs of data on days 6 and 7. Cloud Consumer B was expecting to be billed $10.00, but is billed $35. After raising a complaint, Cloud Consumer B is informed by the cloud provider that cloud consumers are billed based on the allocation of storage space, regardless of how much storage space they actually use.
Which of the following statements describes a solution that can update the cloud architecture to avoid these billing-related problems and discrepancies?
