Cloud Service A is being made available on public Cloud X by Cloud Provider X via the
SaaS delivery model. Cloud Service A is hosted by Physical Server A that also hosts cloud
services being used by different cloud service consumers (and owned by different cloud
Cloud Provider X needs to make Cloud Service A available to a new group of cloud service
consumers, but must do so without the increase in usage volume affecting Cloud Service
Consumers A and B.
Which of the following statements does not accurately describe a solution (or a set of
solutions) that addresses this requirement?
A. Cloud Provider X can scale out Cloud Service A by implementing new cloud computing
mechanisms, such as the virtual server and resource replication mechanisms, which can
enhance the cloud's elasticity characteristic.
B. Cloud Provider X can upgrade its infrastructure to increase the cloud's ubiquitous
access characteristic. This will enable the cloud to provide distributed failover for IT
resources across multiple devices in order to increase its ubiquitous resiliency. To achieve
this, Cloud Provider X will further need to implement the failover system, state
management database and resource replication mechanisms.
C. Cloud Provider X can scale up Cloud Service A by upgrading the Physical Server A
hardware to increase the server's processing power. Cloud Provider X can scale out Cloud
Service A by adding redundant implementations of the service and by using the automated
scaling listener mechanism.
D. Cloud Provider X can upgrade its infrastructure by increasing its ability to horizontally
scale IT resources that are used by Cloud Service A.
Cloud Provider X can upgrade its infrastructure in order to vertically scale IT resources that are used by Cloud Service A.
