Cloud Consumer A (the organization that owns Cloud Service Consumer A) needs regular
access to an external, cloud-based Weather Service that provides up-to-date weather
forecast information. Cloud Providers X, Y and Z are competing public cloud providers,
each offering a Weather Service with the features required by Cloud Consumer A.


Based on the provided statistics, which cloud provider can offer a Weather Service with the
least amount of projected downtime?

문제2
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?

문제3
A company is planning to build and launch a new SaaS product that will be available for
use by the general public. It intends to build the service on-premise and then deploy it in a
public cloud. The company has the following set of four requirements for the
implementation of the new service:
1. The cloud service needs to exchange messages primarily by using HTTP methods and
other features provided by HTTP.
2. The cloud service needs to store highly structured data with potentially complex
relationships.
3. The cloud service needs to be deployed on a dedicated virtual server that can be
administered with a high level of control by the cloud consumer's own cloud resource
administrator.
4. The cloud service needs to be deployed with a minimal amount of integration testing.
For this project, the company has a very limited budget. The company is assessing the IT
resources that are offered by Clouds X and Y within the constraints of its limited budget.
Cloud X can offer an IaaS environment with very few proprietary characteristics that
includes a database that supports only no relational storage, as well as support for the
deployment and usage of REST services.

Cloud Y can offer a PaaS environment with a pre-configured virtual server that includes
native support for WSDL and SOAP, as well as a database that supports only relational
storage. The implementation of a new service within Cloud Y will require compliance to a
high level of proprietary characteristics.
As previously listed, the company has identified four specific implementation requirements
for its new cloud service. Which of the following statements correctly identifies how many of
the four requirements Clouds X and Y can directly fulfill?
