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 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.
• 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 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.
• 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.

A company is planning to build and launch a new SaaS product that will be available for use by the general public. It intends to build the service on-premise and then deploy it in a public cloud. The company has the following set of four requirements for the implementation of the new service:
1.The cloud service needs to exchange messages primarily by using HTTP methods and other features provided by HTTP.
2.The cloud service needs to store highly structured data with potentially complex relationships.
3.The cloud service needs to be deployed on a dedicated virtual server that can be administered with a high level of control by the cloud consumer's own cloud resource administrator.
4.The cloud service needs to be deployed with a minimal amount of integration testing.
For this project, the company has a very limited budget. The company is assessing the IT resources that are offered by Clouds X and Y within the constraints of its limited budget.
Cloud X can offer an IaaS environment with very few proprietary characteristics that includes a database that supports only no relational storage, as well as support for the deployment and usage of REST services.

Cloud Y can offer a PaaS environment with a pre-configured virtual server that includes native
support for WSDL and SOAP, as well as a database that supports only relational storage. The implementation of a new service within Cloud Y will require compliance to a high level of proprietary characteristics.
As previously listed, the company has identified four specific implementation requirements for its new cloud service. Which of the following statements correctly identifies how many of the four requirements Clouds X and Y can directly fulfill?

• A. Cloud X fulfills 2 out of4requirements. Cloud Y fulfills 2 out of4requirements.
• B. Cloud X fulfills 1 out of4requirements. Cloud Y fulfills 3 out of4requirements.
• C. Cloud X fulfills 3 out of4requirements. Cloud Y fulfills 1 out of 4 requirements.
• D. Cloud X fulfills 0 out of 4 requirements. Cloud Y fulfills 4 out of 4 requirements.

Cloud Service Consumer A accesses Cloud Service A (1) that resides in Cloud X. a private cloud owned by the same organization acting as Cloud Consumer A. Cloud Service A processes the message from Cloud Service Consumer A and then sends back a response with the requested data (2). Next, Cloud Service Consumer A sends a message containing some of this data to Cloud Service B (3), which resides in public Cloud Y that is owned by Cloud Provider Y. After processing the message. Cloud Service B sends back a response with additional data to Cloud Service Consumer A (4). Finally, Cloud Service Consumer A writes the data it collected from Cloud Services A and B to Database A (5).
Recently, Cloud Service Consumer A has been required to access Cloud Services A and B at a significantly higher rate, sometimes over 1,000 times within a given workday. This increased usage has not affected Cloud Service B' s performance. Cloud Service A, however, has been generating runtime exceptions, and responses to Cloud Service Consumer A have become increasingly slow and unreliable. It is determined that this decline in performance is due to infrastructure limitations within private Cloud X' s environment. Instead of investing in new infrastructure for Cloud X, it is decided to explore the feasibility of moving Cloud Service A to Cloud Y instead.

Which of the following statements describe valid financial considerations that can be taken into account for assessing the feasibility of this move?

• A. Because, in this scenario, the cost of capital is comprised of the up-front costs added to the ongoing costs, the cost of capital required to move Cloud Service A to Cloud Y will be higher than upgrading Cloud X to accommodate Cloud Service A' s increased usage.
• B. If the existing infrastructure that currently resides in private Cloud X was purchased specifically in support of Cloud Service A, then there may be a financial loss resulting frommoving Cloud Service A out of Cloud X. This can be considered sunk costs that need to be evaluated.
• C. Moving Cloud Service A to Cloud Y will result in the need for Cloud Service A to undergo integration testing to determine how well it can function within Cloud Y and what changes may need to be made to Cloud Service A in order for it to behave as expected. The integration testing and the subsequent changes required for Cloud Service A to function correctly within Cloud Y will incur integration costs that need to be budgeted for.
• D. By moving Cloud Service A to Cloud Y, there may be a decrease in operational governance control over the Cloud Service A implementation. This can increase locked-in costs because Cloud Consumer A may be forced to form dependencies upon proprietary tools used to configure and maintain the Cloud Service A implementation.
