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?

• A.Cloud Provider Y
• B.Any of the three cloud providers, because their availability ratings are identical.
• C.Cloud Provider Z
• D.Cloud Provider X

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 describes a solution that can be used to fulfill
the resiliency requirements of Cloud Service A?

• A.Redundant implementations of Cloud Service A are deployed in all three clouds. The
  failover system mechanism and a special type of automated scaling listener mechanism
  are implemented to establish a system whereby one redundant Cloud Service A
  implementation will automatically take over from another.
• B.A cloud balancing solution is established, whereby an automated scaling listener
  mechanism is implemented on each cloud in such a way that every cloud can automatically
  scale out to another cloud. As a result, if reliability problems occur on any one cloud, the
  subsequent requests will be scaled out to another cloud in a manner that is transparent to
  cloud service consumers.
• C.A cloud balancing solution is established, whereby a resource replication mechanism is
  implemented on each cloud. This allows Cloud Service A to be automatically replicated
  across cloud environments, thereby enabling each implementation of Cloud Service A to
  take the place of another, whenever failure conditions occur.
• D.A failover system mechanism is implemented on Cloud X, which acts as the primary
  point of contact for cloud service consumers. Upon failure conditions occurring, the Cloud
  Service A implementation on Cloud X automatically hands over control of current and
  future message requests from cloud service consumers to Cloud Y.
  Cloud Y retains control of cloud service consumer communication until the next failure condition occurs, at which
  point it hands over control to Cloud Z.
  Finally, if a failure condition occurs in Cloud Z.control is handed back to Cloud X.

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?

• A.Cloud X fulfills 2 out of 4 requirements. Cloud Y fulfills 2 out of 4 requirements.
• B.Cloud X fulfills 3 out of 4 requirements. Cloud Y fulfills 1 out of 4 requirements.
• C.Cloud X fulfills 1 out of 4 requirements. Cloud Y fulfills 3 out of 4 requirements.
• D.Cloud X fulfills 0 out of 4 requirements. Cloud Y fulfills 4 out of 4 requirements.
