SOA Certified Professional Cloud Technology Lab Sample Questions:

1. 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) 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.
B) 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.
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.

2. Organization A has been expanding and, as a result, is outgrowing the processing capacity of its on-premise Service A implementation. It is determined that this is due to usage thresholds of Service A and complex data processing limitations in Database A. The diagram depicts Organization A's current on-premise environment, where Service Consumers A. B and C attempt to access Service A at the same time. Service Consumer A successfully accesses Service A, which then successfully retrieves the requested data (1). Service Consumer B successfully accesses Service A, but due to the complex data structure, the request for the data times out and fails (2). Finally, Service Consumer C attempts to access Service A, but is rejected because Service A is unable to accept more concurrent requests.

Organization A is required to continue using its on-premise Service A implementation, with the exception of Database A, which does not need to remain on-premise. Database A is dedicated to Service A and is comprised of relational data.
Which of the following statements provides a solution that uses cloud-based IT resources to solve the performance limitations of Service A and Database A?

A) A cloud balancing solution can be implemented within the public cloud, whereby a redundant Cloud Service A implementation is established. Cloud Service A becomes the first point of contact for Service Consumers A, B and C (thereby turning them into Cloud Service ConsumersA. B and C). Upon reaching its usage threshold (which will be higher than the on-premise Service A), Cloud Service A automatically routes usage requests to Service A. The resource replication mechanism is implemented within the cloud to establish a replicated Database A that can further be used to load balance data access requests from Cloud Service A or Service A.
B) Automated scaling listener mechanisms can be implemented in both the on-premise and cloud environments. Using built-in resiliency features, these service agents can be configured to coordinate the routing of messages between the on-premise Service A implementation and a redundant Cloud Service A implementation. This dynamic functionality can avoid service usage thresholds in both Service A and Cloud Service A.
C) The virtual server and resource replication mechanisms can be implemented to replicate Service A and Database A across both on-premise and cloud environments. This enables on-demand usage in that requests sent by Service Consumers A, B and C will automatically be redirected to the replicated service and/or database. As a result, Service A' s usage thresholds will no longer result in rejected requests and Database A' s processing limitations will no longer result in failed data access attempts.
D) None of the above.

3. 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 single sign-on mechanism.
B) 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.
C) 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.
D) Virtual Server A was subjected to a denial of service attack that can be mitigated by implementing the encryption and digital signature mechanisms.
