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 Provider X needs to make Cloud Service A available to a new group of cloud service consumers, but must do so without the increase in usage volume affecting Cloud Service Consumers A and B.

Which of the following statements does not accurately describe a solution (or a set of solutions) that addresses this requirement?

• A. Cloud Provider X can scale out Cloud Service A by implementing new cloud computing mechanisms, such as the virtual server and resource replication mechanisms, which can enhance the cloud's elasticity characteristic.
• B. Cloud Provider X can upgrade its infrastructure by increasing its ability to horizontally scale IT resources that are used by Cloud Service A. Cloud Provider X can upgrade its infrastructure in order to vertically scale IT resources that are used by Cloud Service A.
• C. Cloud Provider X can upgrade its infrastructure to increase the cloud's ubiquitous access characteristic. This will enable the cloud to provide distributed failover for IT resources across multiple devices in order to increase its ubiquitous resiliency. To achieve this, Cloud Provider X will further need to implement the failover system, state management database and resource replication mechanisms.
• D. Cloud Provider X can scale up Cloud Service A by upgrading the Physical Server A hardware to increase the server'sprocessing power. Cloud Provider X can scale out Cloud Service A by adding redundant implementations of the service and by using the automated scaling listener mechanism.

Cloud Provider X (which owns Cloud X) deploys two physical servers (Physical Servers A and B) and two databases (Databases A and B). Virtual Servers A and B are hosted by Physical Server A and Ready-Made Environments A and B are hosted by Virtual Server B. Virtual Servers C and D are hosted by Physical Server B. Cloud Service Consumer A regularly accesses Virtual Server D in order to test and deploy a new cloud service that was developed on-premise by the cloud consumer organization operating Cloud Service Consumer A. Cloud Service Consumer B (operated by a different cloud consumer organization) has been regularly accessing Ready-Made Environment A in order to develop and deploy a different new cloud service.
The cloud consumer organizations that own and operate Cloud Service Consumers A and B will soon be ready to launch their respective cloud services for use by their customers. Both cloud consumer organizations are concerned that Cloud X does not provide sufficient security and they demand that Cloud Provider X take the necessary steps to mitigate the denial of service, insufficient authorization and overlapping trust boundaries security threats.

Which of the following statements accurately describes the cloud delivery models used now by the cloud service consumers and in the future by their customers - and - further describes a solution
that fulfills the identified security requirements by implementing a single cloud security mechanism?

• A. Cloud Service Consumer A is using theIaaS delivery model. Cloud Service Consumer B is using the SaaS delivery model. Customers of the cloud services will be using the PaaS delivery model. The encryption mechanism can be implemented to mitigate the denial of service, insufficient authorization and overlapping trust boundaries security threats.
• B. Cloud Provider X is providing a hybrid delivery model comprised of a combination of theIaaS and PaaS delivery models, which means that Cloud Service Consumers A and B are using both theIaaS and PaaS delivery models. Customers of the cloud services will be using the PaaS delivery model. The single sign-on mechanism can be implemented to mitigate the denial of service and insufficient authorization security threats. The encryption mechanisms can be implemented to mitigate the overlapping trust boundaries security challenges.
• C. Cloud Service Consumer A is using theIaaS delivery model. Cloud Service Consumer B is using the PaaS delivery model. Customers of the cloud services will be using the SaaS delivery model. The digital signatures mechanism can be implemented to mitigate the denial of service, insufficient authorization and overlapping trust boundaries security challenges.
• D. Cloud Service Consumer A is using theIaaS delivery model. Cloud Service Consumer B is using the PaaS delivery model.Customers of the cloud services will be using the SaaS delivery model. An identity and access management mechanism can be implemented to mitigate the denial of service, insufficient authorization and overlapping trust boundaries security challenges.

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. 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.
• B. 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
• 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 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.
• D. 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
