最新的 Certified Cloud Computing Specialist C90-03A 免費考試真題：
問題 #1
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. An identity and access management 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. The digital signatures mechanism can be implemented to mitigate the denial of service, insufficient authorization and overlapping trust boundaries security challenges.
問題 #2
Cloud Service Consumer A invokes Cloud Service A from Cloud X (owned by Cloud Provider X) (1). To fulfill the request from Cloud Service Consumer A, Cloud Service A needs to invoke Cloud Service B that resides on Cloud Y (owned by Cloud Provider Y) (2). After completing its processing, Cloud Service B sends a response to Cloud Service A (3). Cloud Service A verifies the response and then finally sends its response to Cloud Service Consumer A (4).
The guaranteed availability of the Cloud Service A implementation is 95% and the guaranteed availability of the Cloud Service B implementation is 95%. Which of the following statements accurately describes the actual availability that Cloud Service Consumer A can receive based on the described scenario?
A. Because Cloud Service Consumer A's response message is processed by two separate cloud
services, the combined availability increases as follows:
1 - (1 - 0.95) X (1 - 0.95) = 0.9975 or 99.75%
B. Because Cloud Service A acts as both a cloud service and cloud service consumer in order to
process Cloud Service Consumer B's request message, Cloud Service A forms a dependency on
Cloud Service B. As a result, the combined availability decreases, as follows:
0.95 X 0.95 = 0.9025 or 90.25%
C. Cloud Service Consumer A benefits from redundant cloud service implementations, thereby
increasing the guaranteed availability as follows:
1 - (1 - (0.95 - 0.1))X (1 - (0.95 - 0.1)) = 0.9775 or 97.75%
D. As a result of the dependency formed by Cloud Service Aon Cloud Service B,the combined availability decreases significantly as follows:
(0.95 X 0.95) - 0.1 = 0.8025 or 80.25%
問題 #3
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 1 out of4requirements. Cloud Y fulfills 3 out of4requirements.
B. Cloud X fulfills 2 out of4requirements. Cloud Y fulfills 2 out of4requirements.
C. Cloud X fulfills 0 out of 4 requirements. Cloud Y fulfills 4 out of 4 requirements.
D. Cloud X fulfills 3 out of4requirements. Cloud Y fulfills 1 out of 4 requirements.
