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?

Cloud X (owned by Cloud Provider X) provides Physical Server A which hosts Virtual Servers A and B. Virtual Server B hosts Ready-Made Environments A and B. Cloud Service Consumer A uses Virtual Server A as part of an IaaS leasing agreement in which Cloud Consumer A is charged a fixed monthly fee for unlimited access. Cloud Service Consumers B and C use Ready-Made Environments A and B respectively as part of a PaaS leasing agreement based on per-minute usage fees. In both cases, access is monitored via Pay-For-Use Monitor A, which keeps track of log-in and log-out times in order to calculate the usage charges that are billed to Cloud Consumers B and C . Virtual Server A begins generating a series of exceptions. Soon thereafter, Virtual Server B becomes destabilized, resulting in further exceptions being raised in Ready-Made Environments A and B. Cloud Service Consumers B and C receive a series of error messages until both of their connections are dropped Finally, Physical Server A shuts down completely. A subsequent investigation reveals that Virtual Server A was the victim of a security attack performed by a malicious cloud service consumer, the attacker generated increased loads of external communication requests on Virtual Server A and the underlying network, causing Physical Server A (along with Virtual Server B) to eventually shut down.

Which of the following statements accurately identifies the type of security threat that corresponds to the described attack - and -provides a solution that can directly mitigate this type of security threat within Cloud X?

Cloud Provider Y owns Cloud Y, which provides a set of cloud services, virtual servers, and one physical server. Cloud Services A and B are hosted on Virtual Server A, which is hosted by Physical Server A . Physical Server A also hosts Virtual Server B, which hosts redundant implementations of Cloud Services A and B for load balancing purposes. Cloud Service Consumer A is accessing Cloud Service A located on Virtual Server A . Cloud Service Consumer B is accessing Cloud Service B located on Virtual Server B . Cloud Service Consumers A and B are both owned by Cloud Consumer X. Cloud Consumer X has recently complained that Cloud Service A is becoming increasingly unreliable. Cloud Provider Y launches an investigation that reveals that Virtual Server A has been crashing sporadically due to successful malicious intermediary attacks where malicious service agents have been inserting harmful data into messages sent by Cloud Service Consumer A to Cloud Service A

Which of the following statements describes a solution that can mitigate the malicious intermediary attacks that have been occurring on Virtual Server A - and - can further help prevent the same types of attacks from occurring on Virtual Server B?

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 describe how a cloud balancing solution can be implemented to fulfill the resiliency requirements of Cloud Service A?

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.

Cloud X is a private cloud that, to-date, has been set up within the cloud provider company to provision IT resources free of charge to internal cloud consumers, via PaaS and IaaS delivery models. The cloud consumers that have been operating Cloud Service Consumers A and B represent different IT departments within the company that have been working separately on the development of new cloud services. Cloud Service Consumer A has been accessing Virtual Server D to make necessary configurations and administration settings for the upcoming deployment of a new cloud service that was previously developed outside of Cloud X. Cloud Service Consumer B has been accessing Ready-Made Environment A to develop and now deploy a different new cloud service. Cloud Provider X (which is represented by a separate IT department dedicated to governing and administering Cloud X) determines that it will need to introduce three specific enhancements to Cloud X in order to accommodate both upcoming cloud services. First, it needs to add a way to charge cloud consumers for the usage of cloud services. Secondly, it needs to add a way for new cloud services to be automatically scaled. Finally, it needs to add a way for a cloud consumer to be automatically notified when a cloud service encounters runtime loads that exceed its allocated usage threshold. Which of the following statements accurately describes a solution that fulfills all three identified requirements?
