Cloud Service Consumer A invokes Cloud Service A from Cloud X (owned by Cloud Provider X) (1). To
fulfill the request from Cloud Service Consumer A, Cloud Service A needs to invoke Cloud Service B
that resides on Cloud Y (owned by Cloud Provider Y) (2). After completing its processing, Cloud
Service B sends a response to Cloud Service A (3). Cloud Service A verifies the response and then
finally sends its response to Cloud Service Consumer A (4).
The guaranteed availability of the Cloud Service A implementation is 95% and the guaranteed
availability of the Cloud Service B implementation is 95%. Which of the following statements
accurately describes the actual availability that Cloud Service Consumer A can receive based on the
described scenario?
Question No 2
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?
Question No 3
Cloud Provider X has deployed a virtualization environment in Cloud X comprised of Physical Server A
hosting Virtual Servers A and B. Cloud Provider X implements Cloud Service A on Virtual Server A and
makes it available to Cloud Service Consumer A, which interacts with Cloud Service A by sending and
receiving messages (1, 2). Cloud Provider Y has deployed a virtualization environment comprised of
Physical Server B hosting Virtual Servers C and D. Virtual Server C is made available to Cloud Service
Consumer B, which interacts with Virtual Server C (3,4) in order to prepare for the deployment of a
new cloud service that will be used internally by Cloud Provider Y to process data obtained from
Cloud Service A .
Cloud Consumer Z and Cloud Provider X belong to the same organization. Cloud Provider Y is a third -
party organization. Which of the following statements provides a valid scenario that accurately
describes the involvement of cloud deployment models, cloud delivery models, roles and/or
boundaries? (Note that the correct answer represents one of multiple valid scenarios that can exist.)
