SOA Cloud Technology Concepts - C90.02 Exam Practice Test

Cloud balancing cannot be achieved by redundantly deploying IT resources in advance. Redundant instances of IT resources must be dynamically generated on-demand, at runtime.

The required parts of a SOAP message are the envelope document and the header and body sections.

The single sign-on security mechanism helps mitigate which of the following threats?
Select the correct answer.

Cloud balancing can be used to increase both the availability and scalability of IT resources.

A ____________________ is a pre-defined cloud-based platform comprised of a set of already installed IT resources that can be used and customized by a cloud consumer.

Which of the following are data-oriented security mechanisms?

Cloud Service A resides on Virtual Server A and Cloud Service B resides on Virtual Server B.
Both virtual servers are hosted by the same physical server and the trust boundaries of Cloud Services A and B overlap. A cloud service consumer successfully uses Cloud Service A to gain access to the underlying physical server. This enables the cloud service consumer to attack Cloud Service B, which negatively affects the cloud service consumers of Cloud Service B.
This is an example of which cloud security threat?

Cloud services cannot be built as components that use proprietary technologies, such as Java and .NET. This is because the use of Web-based communication technology is required in order for a service to be cloud-based.

A cloud service built as a SOAP-based Web service will have a service contract that is physically decoupled from the service's logic.
