SOA Certified Professional Cloud Technology Lab Sample Questions:

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.

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 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.
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 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.
D) 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.

2. 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?

A) Virtual Server A was subjected to an insufficient authorization attack that can be mitigated by implementing the digital signature and hardened virtual server image mechanisms.
B) Virtual Server A was subjected to a denial of service attack that can be mitigated by implementing the encryption and digital signature mechanisms.
C) Virtual Server A was subjected to a denial of service attack that can be mitigated by implementing the hardened virtual server image and identity and access management mechanisms.
D) Virtual Server A was subjected to an insufficient authorization attack that can be mitigated by implementing the single sign-on mechanism.

3. 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?

A) Using a PaaS environment, the cloud service owner can configure a primary Cloud Service A implementation on Cloud X so that when failure conditions occur, message requests from cloud service consumers are automatically routed to a redundant on-premise implementation of Cloud Service A. This requires the implementation of the failover system and resource replication mechanisms.
B) Clouds X, Y and Z are equipped with failover system mechanisms and specialized types of automated scaling listener mechanisms in order to establish cross-cloud resiliency. Cloud Service A is configured so that Clouds X, Y and Z can dynamically generate redundant instances on-demand.
C) Cloud Service A is redundantly deployed in advance within Clouds X. Y and Z and is further supplemented with failover system mechanisms and specialized types of automated scaling listener mechanisms.
D) A type of automated scaling listener that can also be considered a cloud monitor is implemented in Clouds X, Y and Z toestablish a system whereby each cloud can assume controlof cloud service consumer message exchanges. This results in resilient cloud balancing, as opposed to on-demand cloud balancing.
