SOA Certified Professional Cloud Technology Lab 認定 C90-03A 試験問題：
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 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.
- 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 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.
正解：C 🗳️
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. Public Cloud Y charges for the use of its IT resources. Moving Cloud Service A to Cloud Y can therefore result in new on-going costs. Although Cloud Service A may be able to share some of the existing IT resources used by Cloud Service B, it will likely incur new on-going costs that need to be budgeted for.
- B. Once Cloud Service A is deployed in Cloud Y, it may form dependencies upon proprietary parts of Cloud Y that may limit its mobility should it be decided to move it outside of Cloud Y in the future. This can incur further locked-in costs that need to be accounted for.
- C. By moving Cloud Service A to Cloud Y, the SaaS delivery model will be established for Cloud Service A, thereby allowing the service implementation to build upon existing infrastructure from underlying PaaS and laaS delivery models that would have been required for Cloud Service B to be implemented in Cloud Y.
- D. Moving Cloud Service A to Cloud Y will require that Database A also be moved to Cloud Y due to the need for Cloud Service A and Database A to share a common virtual server within the same organizational boundary, as required by the cloud-based security group. The move of Database A will increase the integration testing effort and. as a result, will also increase the overall integration costs.
正解：A、B 🗳️
Cloud Consumer A (the organization that owns Cloud Service Consumer A) needs regular access to an external, cloud-based Weather Service that provides up-to-date weather forecast information. Cloud Providers X, Y and Z are competing public cloud providers, each offering a Weather Service with the features required by Cloud Consumer A.
Based on the provided statistics, which cloud provider can offer a Weather Service with the least amount of projected downtime?
- A. Any of the three cloud providers, because their availability ratings are identical.
- B. Cloud Provider X
- C. Cloud Provider Y
- D. Cloud Provider Z
正解：B 🗳️
