Free C90-06A Sample Questions:

Q: 1
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).
(Exhibit is not available in this demo)
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?
A. The Elastic Network Capacity pattern can be applied to implement a system that dynamically assigns network ports to Virtual Server A before its processing capacity thresholds are reached. The Redundant Physical Connection for Virtual Servers pattern can be applied to create an alternative path to LUN B in Cloud Storage Device B. The Resource Pooling pattern can be applied to synchronize Cloud Storage Device A with other cloud storage devices.
B. The Resource Reservation pattern can be applied to dynamically provision resources to Virtual Server A whenever its processing thresholds are being reached. The Persistent Virtual Network Configuration pattern can be applied to establish a persistent hyperlink to LUN B over the virtual network that cannot be lost. The Elastic Resource Capacity pattern can be applied to prevent Cloud Storage Device A from encountering resource constraints.
C. The Elastic Resource Capacity pattern can be applied to establish a system that can dynamically allocate resources to Virtual Server A. The Multipath Resource Access pattern can be applied to establish a multipathing system that can provide an alternative path to LUN B in Cloud Storage Device B. The Resource Reservation pattern can be applied to establish a system that enables Organization A to have exclusive access to pre-defined resources on Cloud Storage Device A for a given period of time.
D. None of the above.
