NO.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 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 failover system mechanism is implemented on Cloud X, which acts as the primary point of contact for
cloud serviceconsumers. 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 serviceconsumer 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.
D. 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.
Answer: A

NO.2 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?
A. Because Cloud Service Consumer A's response message is processed by two separate cloud
services, the combined availability increases as follows:
1.- (1 - 0.95) X (1 - 0.95) = 0.9975 or 99.75%
B. Because Cloud Service A acts as both a cloud service and cloud service consumer in order to
process Cloud Service Consumer B's request message, Cloud Service A forms a dependency on
Cloud Service B. As a result, the combined availability decreases, as follows:
0.95 X 0.95 = 0.9025 or 90.25%
C. Cloud Service Consumer A benefits from redundant cloud service implementations, thereby
increasing the guaranteed availability as follows:
1.- (1 - (0.95 - 0.1))X (1 - (0.95 - 0.1)) = 0.9775 or 97.75%
D. As a result of the dependency formed by Cloud Service Aon Cloud Service B,the combined availability
decreases significantly as follows:
(0.95 X 0.95) - 0.1 = 0.8025 or 80.25%
Answer: B
