SOA Certified Professional Cloud Technology Lab Sample Questions:
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?
- A. Cloud Provider Y can implement the encryption and digital signatures mechanisms to protect the contents of messages from being augmented by malicious service agents.
- B. Cloud Provider Y can implement the failover system mechanism by requiring that redundant copies of all service agents be deployed. This will reduce the chances of any one service agent performing malicious actions at runtime.
- C. Cloud Provider Y can implement the cloud-based security group mechanism that establishes a logical trust boundary that encompasses Virtual Servers A and B.
- D. Cloud Provider Y can implement the identity and access management mechanism for Virtual Servers A and B by physically deploying this mechanism on Physical Server A and then further implementing the resource replication mechanism to propagate the identity and access management system across Virtual Servers A and B.
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 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.
- B. 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.
- C. 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.
- D. 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.
Cloud Service A is being made available on public Cloud X by Cloud Provider X via the SaaS delivery model. Cloud Service A is hosted by Physical Server A that also hosts cloud services being used by different cloud service consumers (and owned by different cloud service owners).
Cloud Provider X needs to make Cloud Service A available to a new group of cloud service consumers, but must do so without the increase in usage volume affecting Cloud Service Consumers A and B.
Which of the following statements does not accurately describe a solution (or a set of solutions) that addresses this requirement?
- A. Cloud Provider X can scale up Cloud Service A by upgrading the Physical Server A hardware to increase the server'sprocessing power. Cloud Provider X can scale out Cloud Service A by adding redundant implementations of the service and by using the automated scaling listener mechanism.
- B. Cloud Provider X can scale out Cloud Service A by implementing new cloud computing mechanisms, such as the virtual server and resource replication mechanisms, which can enhance the cloud's elasticity characteristic.
- C. Cloud Provider X can upgrade its infrastructure by increasing its ability to horizontally scale IT resources that are used by Cloud Service A. Cloud Provider X can upgrade its infrastructure in order to vertically scale IT resources that are used by Cloud Service A.
- D. Cloud Provider X can upgrade its infrastructure to increase the cloud's ubiquitous access characteristic. This will enable the cloud to provide distributed failover for IT resources across multiple devices in order to increase its ubiquitous resiliency. To achieve this, Cloud Provider X will further need to implement the failover system, state management database and resource replication mechanisms.
