SOA Cloud Architecture Lab - C90.06 Exam Practice Test
Cloud Service A requires access to Cloud Storage Device A, which contains LUNs A and
B. Cloud Service A is hosted by Virtual Server A, which resides on Hypervisor A on Physical Server A.
Virtual Server B hosts Cloud Service B and Cloud Service C.
Cloud Service Consumer A accesses Cloud Service A (1), which then accesses LUN A or B on Cloud Storage Device A (2). After receiving the requested data from Cloud Service A, Cloud Service Consumer A forwards the data to Cloud Service B (3), which then writes it to Cloud Storage Device B (4).
Cloud Service Consumer A belongs to Organization A.
Organization A uses LUN A and LUN B on Cloud Storage Device A to store their important client account data. Cloud Storage Device A is a low-performance cloud storage device, which begins to cause performance issues as more data is added to LUNs A and B and as Cloud Service Consumer A performs data access requests more frequently. Organization A asks that its cloud architecture be upgraded to process increased quantities of data and higher volumes of data requests.
Organization A has been leasing a PaaS environment that it used to build Cloud Service A, which it would like to make available to the general public. Organization A needs to establish a system capable of monitoring usage of Cloud Service A for billing purposes.
The cloud provider is using a usage data collection and reporting system that gathers information on Organization A's hosted IT resources approximately ten hours after the time of usage. One day, Organization A attempts to retrieve information on whether Virtual Server B has available Cloud Service C instances. They discover that they are unable to obtain the current status of Virtual Server B.
Organization A demands a system that provides instant availability reporting.
Which of the following statements lists the patterns that can be applied to solve these three requirements and problems?

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.
