1. Cloud Service A is being made available on public Cloud X by Cloud Provider X via the SaaS delivery model. Cloud Service A is hosted by Physical Server A that also hosts cloud services being used by different cloud service consumers (and owned by different cloud service owners).
Cloud Service Consumers A and B access Cloud Service A on a regular basis and Physical Server A has been able to accommodate the resulting usage load After reviewing the implementation environment for Cloud Service A. Cloud Provider X determines it needs to enhance the ubiquitous access and multi-tenancy characteristics within this part of Cloud X.

Which of the following statements accurately describes a solution that fulfills all of these requirements?

A) The resource replication mechanism can be introduced to address ubiquitous access requirements by broadening the range of cloud service consumers that can use Cloud Service A via standard service replication. The virtual server mechanism can be implemented to enable multi-tenancy via each service replication resulting from the application of the resource replication mechanism.
B) The resilient computing mechanism can be implemented to address ubiquitous access requirements by making Cloud Service A available to a broader range of cloud service consumer devices, including desktops running Web browsers and various mobile devices. The resource replication mechanism can be implemented to enable multi-tenancy within the Cloud Service A implementation.
C) The multi-device broker mechanism can be implemented to address ubiquitous access requirements by broadening the range of cloud service consumers that can access Cloud Service The resilient computing mechanism can be implemented to establish the multitenancycapabilities of Cloud Service A so that it will be able to resiliency accommodate the additional cloud service consumer devices that will gain access to it.
D) The multi-device broker mechanism can be implemented to address ubiquitous access requirements by broadening the range of cloud service consumers that can access Cloud Service A. The virtual server mechanism can be implemented to establish the multitenancy capabilities of Cloud Service A.

2. Cloud Provider X has deployed a virtualization environment in Cloud X comprised of Physical Server A hosting Virtual Servers A and B. Cloud Provider X implements Cloud Service A on Virtual Server A and makes it available to Cloud Service Consumer A, which interacts with Cloud Service A by sending and receiving messages (1, 2).
Cloud Provider Y has deployed a virtualization environment comprised of Physical Server B hosting Virtual Servers C and D. Virtual Server C is made available to Cloud Service Consumer B, which interacts with Virtual Server C (3,4) in order to prepare for the deployment of a new cloud service that will be used internally by Cloud Provider Y to process data obtained from Cloud Service A.

Cloud X is administered by a group of organizations and makes Cloud Service A available only to cloud service consumers from that group. Cloud Consumer Z belongs to one of the organizations within this group. Cloud Y and Cloud Consumer Z are owned by the same organization. Which of the following statements provides a valid scenario that accurately describes the involvement of cloud deployment models, cloud delivery models, roles and/or boundaries? (Note that the correct answer represents one of multiple valid scenarios that can exist.)

A) Clouds X and Y are based on the community cloud deployment model. Cloud Service A is based on the SaaS delivery model. Virtual Server C is being offered as part of the PaaS delivery model. A cloud resource administrator working for Cloud Provider X uses Virtual Server A to access the Cloud Service A implementation Cloud Consumer T s trust boundary encompasses Cloud Service Consumers A and B, Cloud Service A and Virtual Server C. The organization that owns Cloud Consumer Z is the cloud service owner of Cloud Service
B) Cloud X is based on the community cloud deployment model. Cloud Service A is based on the SaaS delivery model. Cloud Y is based on the private cloud deployment model. Virtual Server C is being offered as part of theIaaS delivery model. A cloud resource administrator working for Cloud Consumer Z uses Cloud Service Consumer B to access Virtual Server C. Cloud Consumer Z is the cloud service owner of Cloud Service A. Cloud Consumer T's organizational boundary encompasses Cloud Service Consumers A and B. Cloud Consumer Z's trust boundary encompasses Cloud Service A and Virtual Server C.
C) Cloud X is based on the community cloud deployment model. Cloud Service A is based on the SaaS delivery model. Cloud Y is based on the private cloud deployment model. Virtual Server C is being offered as part of theIaaS delivery model. A cloud resource administrator working for Cloud Consumer Z uses Cloud Service Consumer B to access Virtual Server Cloud Consumer Z' s trust boundary encompasses Cloud Service Consumers A and B, as well as Cloud Service A and Virtual Server The organization that owns Cloud Consumer Z will be the cloud service owner of the new cloud service that will be deployed on Virtual Server
D) Cloud X is based on the hybrid cloud deployment model. Cloud Service A is based on the SaaS delivery model. Cloud Y isbased on the community cloud deployment model. Virtual Server C is being offered as part of theIaaS delivery model. A cloud resource administrator working for Cloud Consumer Z uses Cloud Service Consumer A to access Cloud Service A.Cloud Consumer Z's organizational and trust boundaries encompass Cloud Service Consumers A and B, Cloud Service A and Virtual Server C.

3. The cloud service owner of Cloud Service A is evaluating Clouds X, Y and Z to determine which cloud environment can offer the greatest level of reliability. All three clouds are geographically dispersed across three separate time zones. As a result, each cloud experiences usage peaks at different times. Based on the metrics provided, the greater the usage of a cloud, the lower its reliability. When the cloud service owner complains to Cloud Provider A (the owner of all three clouds) that none of the clouds provide an adequate level of reliability, Cloud Provider A suggests a solution that increases resiliency.

Which of the following statements accurately describes a solution that can be used to fulfill the resiliency requirements of Cloud Service A?

A) A cloud balancing solution is established, whereby a resource replication mechanism is implemented on each cloud. This allows Cloud Service A to be automatically replicated across cloud environments, thereby enabling each implementation of Cloud Service A to take the place of another, whenever failure conditions occur.
B) A cloud balancing solution is established, whereby an automated scaling listener mechanism is implemented on each cloud in such a way that every cloud can automatically scale out to another cloud. As a result, if reliability problems occur on any one cloud, the subsequent requests will be scaled out to another cloud in a manner that is transparent to cloud service consumers.
C) Redundant implementations of Cloud Service A are deployed in all three clouds. The failover system mechanism and a special type of automated scaling listener mechanism are implemented to establish a system whereby one redundant Cloud Service A implementation will automatically take over from another.
D) A failover system mechanism is implemented on Cloud X, which acts as the primary point of contact for cloud serviceconsumers. Upon failure conditions occurring, the Cloud Service A implementation on Cloud X automatically hands over control of current and future message requests from cloud service consumers to Cloud Y. Cloud Y retains control of cloud serviceconsumer communication until the next failure condition occurs, at which point it hands over control to Cloud Z. Finally, if a failure condition occurs in Cloud Z. control is handed back to Cloud X.
