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.

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?

Virtual Server A and Virtual Server B are hosted by Hypervisor A, which resides on Physical Server A.
Virtual Server A hosts Cloud Service A. Virtual Server C. Virtual Server D, Virtual Server E and Virtual
Server F are hosted by Hypervisor B on Physical Server B. Physical Server C, which hosts Hypervisor C, is currently not being used.
Cloud Service Consumer A accesses Cloud Service A (1), which accesses files stored in a folder on Virtual
Server A (2). Cloud Consumer B uses Proprietary User Portal A to administer legacy software (not shown) installed on Virtual Server D (3). Proprietary User Portal B and Proprietary User Portal C are also available
for accessing additional legacy systems located on Virtual Server F; however, they are not often used.
The cloud shown in the figure is a private cloud. Department A and Department B share IT resources within the private cloud and are part of the same organization. Cloud Service Consumer A belongs to Department
A and Cloud Consumer B belongs to Department B.
During routine access of Cloud Service A by Cloud Service Consumer A, the Department A cloud resource administrator is notified that a hardware fault is occurring within Physical Server A that will soon cause it to
fail. The cloud resource administrator scrambles to arrange for Cloud Service A to be relocated but is unable to do so before Physical Server A does fail. It takes several more hours of downtime until, with the
cooperation of the cloud provider, the Cloud Service A implementation is successfully moved to Physical
Server C and made live again. Managers at Department A demand that a system be put in place to avoid this scenario in the future.
Cloud Service A was initially developed specifically for Department A's Cloud Service Consumer A.
However, recently Department B has indicated that it will be developing its own cloud service consumer that will also need to regularly access Cloud Service A. After this new cloud service consumer is deployed, both
Department A and Department B experience occasional runtime errors when their cloud service consumers attempt to access Cloud Service A at the same time.
Cloud Service A accesses a legacy system on Virtual Server A that requires regular updates and patches to stay current. Each time the legacy system is updated, Cloud Service A needs to undergo an update as well, during which it needs to be temporarily unavailable. Department A managers ask the cloud provider to extend the cloud architecture so that a duplicate, secondary implementation of Cloud Service A can be made available while the primary implementation undergoes a maintenance update.
Which of the following statements provide a solution that can adequately resolve all of Departments A and B's issues?
Virtual Server A hosts Cloud Service A. Virtual Server C. Virtual Server D, Virtual Server E and Virtual
Server F are hosted by Hypervisor B on Physical Server B. Physical Server C, which hosts Hypervisor C, is currently not being used.

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.

Cloud Storage Device A contains LUN A and can be accessed by external cloud consumers via a proprietary user portal that is used primarily by cloud consumers to upload and manage data for backup
purposes. Pay-Per-Use Monitor A tracks the amount of data being uploaded and forwards this information to a billing management system. Cloud Storage Device B is a secondary cloud storage device. Data from
Cloud Storage Device A is replicated synchronously to Cloud Storage Device B using a storage replication program (not shown). Cloud Storage Device A is further administered by a cloud resource administrator
that works for the cloud provider, who accesses the cloud storage device via an internal usage and administration portal.
Three different cloud consumers (Sarah. William, Matilda) access Cloud Storage Device A to upload data for backup purposes (1). These three cloud consumers belong to different departments within the same
organization, and therefore all three share LUN A. Pay-Per-Use Monitor A collects the storage space data and forwards it to the billing management system (2). The cloud provider offers premium and discount storage plans. With the premium plan, the data stored on Cloud Storage Device A is also replicated to
Cloud Storage Device B. With the discount plan, the data stored on Cloud Storage Device A is not replicated. Both plans are based on fixed-disk storage allocation. The cost of the premium plan is $5 per week for every GB of storage space and the cost of the discount plan is $2 per week for every GB of storage space. The SLA from the cloud provider guarantees availability of 97% for access to Cloud Storage
Device A.
The three cloud consumers use Cloud Storage Device A as follows:

Cloud Service Consumer A accesses Cloud Service A (1). Cloud Service Consumer B accesses Cloud Service A (2). Cloud Service Consumer C accesses Cloud Service A (3) and then accesses Cloud Service
B (4).
Cloud Service Consumers A, B and C simultaneously access Cloud Service A. Cloud Service Consumer C receives a runtime exception and its request for access is rejected. It is determined that Cloud Service
Consumer C attempted to upload a large amount of input data for Cloud Service A, which exceeded the bandwidth threshold of the virtual network. The cloud architecture needs to be improved to avoid this from
happening again.
Cloud Service Consumer C's repeated access of Cloud Service B imposes workloads that are large and highly unpredictable. After some time, Cloud Service B begins to delay its responses and sometimes times
out entirely. The cloud resource administrator discovers that Virtual Server B is unstable and close to failure primarily because its CPU and memory resources are being used to their maximum capacity.
Cloud Services C and D are being positioned as SaaS products for use by a range of cloud consumer organizations. After their initial release, they begin to quickly use up the available memory in Virtual Server
C, primarily because of the large amounts of state and session data they need to place into memory for extended periods.

Cloud Service A and Cloud Service B perform different functions but both share access to Cloud Storage
Device A when fulfilling requests from cloud service consumers that require data access. Cloud Services A and B are hosted by Virtual Server A, which is hosted by Hypervisor A on Physical Server A.
Cloud Service Consumer A accesses Cloud Service A to issue a request for data (1). Cloud Service A queries a database in Cloud Storage Device A to retrieve the data (2). Upon receiving the requested data, Cloud Service Consumer A combines it with additional data to form a new collection of data. Cloud Service
Consumer A then accesses Cloud Service B and provides it with the new data (3). Cloud Service B accesses a different database in Cloud Storage Device A to store the new data (4). Cloud Consumer B
accesses the usage and administration portal to upload new data (5). The data is uploaded to Cloud
Storage Device B (6).
Cloud Service Consumer A belongs to Organization A. Cloud Consumer B belongs to Organization B.
Cloud Service A is a SaaS product offered by the cloud provider to the general public, and is therefore used by numerous cloud consumers from different organizations at different times. Cloud Service B is also a
SaaS product as part of the same overall solution as Cloud Service A. However, because a given cloud service consumer only needs to access Cloud Service B when the data it receives from Cloud Service A
meets certain criteria, it is not used nearly as much as Cloud Service A. Cloud Service A currently has a hard threshold allowing no more than 10 concurrent instances of it to exist at once. One day, Cloud Service
Consumer A attempts to access Cloud Service A as the eleventh cloud service consumer, and is
predictably rejected.
Cloud Service Consumer A belongs to Organization A, one of the cloud provider's most important customers. Therefore, when Organization A complains about not being able to access Cloud Service A
during peak usage times, the cloud provider agrees to provide a solution. As a result of a natural disaster, the cloud provider's data center that houses Physical Server A becomes unexpectedly unavailable. Physical
Server A subsequently becomes unavailable for nearly two days. This outage exceeds what the cloud provider guaranteed in its original SLA and the cloud provider agrees to not charge Organization for usage fees for an entire month as compensation. However, the unavailability of Physical Server A had a significant impact on Organization As business, resulting in financial loss and loss of confidence of its clients.
Organization A informs the cloud provider that it cannot continue working with this cloud unless the cloud provider can guarantee that the availability of Physical Server A will no longer be dependent on a single
data center or a single geographic region.
Organization B receives its latest monthly invoice from the cloud provider and discovers that the charges are identical to the invoice it received last month, even though the usage and administration portal shows
that its data usage is a third less. They bring this issue to the attention of the cloud provider and are informed that they are currently subscribed to a fixed-allocation plan. The cloud provider explains that in order to get them on a plan whereby they are charged only for actual data usage, Cloud Storage Device B would need to be upgraded and a system capable of tracking runtime usage would need to be established. Organization B asks the cloud provider to make these changes.
