SOA Certified Professional Cloud Technology Lab 認定 C90-03A 試験問題:

1. 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) 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%
B) 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%
C) 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%
D) 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%

2. 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?

A) The pay-for-use monitor mechanism can be installed to address the requirement for cloud service usage charges to be tracked and recorded. The automated scaling listener mechanism can be implemented to address the requirement for cloud services to be automatically scaled. The multi-device broker mechanism can be implemented to address the requirement for notifications to be issued when cloud service loads exceed thresholds.
B) The pay-for-use monitor mechanism can be implemented to address the requirement for cloud service usage charges to betracked and recorded, for cloud services to be automatically scaled, and for notifications to be issued when cloud service loads exceed thresholds.
C) The pay-for-use monitor mechanism can be installed to address the requirement for cloud service usage to be tracked andrecorded. The automated scaling listener mechanism can be implemented to address both the requirement for cloud services to be automatically scaled and for notifications to be issued when cloud service loads exceed thresholds.
D) The state management database mechanism together with the virtual server mechanism and the automated scaling listener mechanism can be implemented to address the requirement for cloud service usage charges to be tracked and recorded, for cloud services to be automatically scaled, and for notifications to be issued when cloud service loads exceed thresholds.

3. 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) 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.
B) 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.
C) 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.
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.
