Arcitura Education C90.06 Exam - Topic 1 Question 9 Discussion

Virtual Server A is hosted by Hypervisor A, which resides on Physical Server A. Virtual Server A

hosts Cloud Services A and B. Virtual Server B is hosted by Hypervisor B on Physical Server B.

Physical Server C is currently not being used.

Cloud Service Consumer A sends a request to Cloud Service A that is intercepted by Pay-Per-Use

Monitor A

(1), which collects billing-related usage data that is later forwarded to the billing management system

(2). Cloud Service A receives and processes the request

(3). Cloud Consumer B accesses the usage and administration portal

(4) to access data on Cloud Storage Device B. Pay-Per-Use Monitor B intercepts the data access to collect and forward billing-related usage data to the billing management system

(5). Cloud Storage Device B processes the data access request from Cloud Consumer B

(6).

Cloud Service Consumer A and Cloud Consumer B belong to Organization A

Cloud Storage Device B is accessed on a regular basis by Cloud Consumer B. However,

managers at Organization A receive reports from their cloud resource administrator that Cloud Storage Device B is unavailable for longer periods and more frequently than what they expected, based on the SLA availability guarantee they were provided by the cloud provider. This results in wasted time when the cloud resource administrator attempts to upload or access data and then discovers that Cloud Storage Device B is unavailable. The cloud resource administrator requires a means of checking for the availability of Cloud Storage Device B prior to attempting access.

As the workload increases on Physical Server B, Cloud Consumer B begins to receive runtime exceptions and degraded data access performance from Cloud Storage Device B. It is determined that the cause of the deteriorating performance is a network bottleneck that has formed on Physical Server B due to its bandwidth capacity being reached, primarily because of other cloud consumer organizations also sharing its hosted IT resources.

Organization A receives a monthly billing statement that shows the charges for the total usage of Cloud Service A during that period. However, Organization A requires a more detailed breakdown of the types of usage and their associated costs. For example, Cloud Service Consumer A can issue requests for information by employees within Organization A and on behalf of clients of Organization A. Organization A requires a breakdown of the usage costs incurred on behalf of clients so that it can bill the clients for this usage accordingly. The cloud provider informs Organization A that it has no existing monitor that can collect and log this detailed usage information and suggests that Organization A customize its own monitor.

Which of the following statements lists the patterns that can be applied to solve these three problems?
