Cloud Service A accesses LUN Aon Cloud Storage Device A when it receives requests to process data from cloud consumers. Cloud Service A is hosted by Virtual Server A.
The usage and administration portal can be used to access and manage the data in Cloud Storage Device B, which is also hosted by Virtual Server A.
Virtual Server A is further hosted by Hypervisor A, which resides on Physical Server A.
Virtual Server B is part of a virtual server cluster hosted by Hypervisor B.
which resides on Physical Server B.
Physical Server C is not in use and does not yet have an operating system installed.
Cloud Service Consumer A sends a request to Cloud Service A (1), which accesses data in LUN Aon Cloud Storage Device A (2). Cloud Consumer B uses the usage and administration portal to upload new data (3). The data is placed in LUN B on Cloud Storage Device B (4).
Cloud Service Consumer A and Cloud Consumer B belong to Organization A, which is leasing Virtual Server A and Virtual Server B from the cloud provider. Organization A also proceeds to lease Physical Server C as part of a new laaS agreement it signs with the cloud provider.
Organization A wants to provision Physical Server C with a number of legacy systems that cannot be deployed on virtual servers. However, when it attempts to do so, it realizes that its laaS package only provides Physical Server C as an out-of-the-box hardware server without anything installed on it. In order to deploy its legacy systems Organization A requires that Physical Server C first has an operating system installed, but it has no means of remotely provisioning Physical Server C with an operating system.

Organization A would like to deploy two of its legacy systems on Virtual Server A and to further extend Cloud Service A's functions so that it can be used as an external interface for cloud service consumers to access legacy system features. Additionally, Organization A would like to deploy three of its mission-critical legacy systems on Virtual Server B in order to take advantage of the additional performance and failover benefits provided by the virtual server cluster that Virtual Server B is part of. Each of the five legacy systems is comprised of dozens of components that need to be installed individually. Instead of manually installing each component of each legacy system, Organization A would like to customize workflows that can automate these deployment tasks.
During the first few months of working with its cloud-based legacy systems. Organization A receives a number of complaints from users that the cloud-based legacy systems are at times behaving erratically. However, when cloud resource administrators with Organization A review the cloud provider's reports that log usage, downtime and other runtime characteristics, they do not find any indication of erratic behavior or any other comparable problems. After some further investigation, the cloud resource administrators determine that the nature of the erratic behavior is specific to proprietary features of the legacy systems and is therefore not monitored or logged by the cloud provider's standard audit monitor, pay-per-use monitor or automated scaling listener. The cloud resource administrators recommend that a new service agent be developed with features customized to monitor the legacy systems.
Which of the following statements provides a solution that can address Organization A's requirements?

• A. The Bare-Metal Provisioning pattern can be applied to enable Organization A to provisioning Physical Server C with legacy systems after the operating system has been installed. The Synchronized Operating State pattern can be applied to consolidate Organization A's legacy systems via a centralized administration portal from which it can then automate their deployment. The Automated Administration pattern can be applied to establish a series of workflow scripts customized to monitor and log proprietary legacy system behavior.
• B. The Bare-Metal Provisioning pattern can be applied to remotely provision Physical Server C with the operating system required to deploy the legacy systems. The Automated Administration pattern can be applied to enable Organization A to create custom scripts that can carry out the deployment of the legacy system components via the use of an intelligent automation engine. To provide Organization X with the tools to monitor IT resource usage and collect usage data so that security breaches and other impacts do not occur, the Usage Monitoring pattern can be applied to establish the required custom monitoring functionality.
• C. None of the above.
• D. The Rapid Provisioning pattern can be applied to enable Physical Server C to be remotely provisioned with the operating system and legacy systems. The Centralized Remote Administration pattern can be applied to enable Organization A's employees to remotely manage and administer legacy system deployment. The Pay-as-You-Go pattern can be applied to establish the custom monitoring functionality required by Organization A's legacy systems.

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?

• 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. None of the above.
• D. 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.
