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
service owners).
Cloud Service Consumers A and B access Cloud Service A on a regular basis and
Physical Server A has been able to accommodate the resulting usage load After reviewing
the implementation environment for Cloud Service A.
Cloud Provider X determines it needs to enhance the ubiquitous access and multi-tenancy characteristics within this part of Cloud
X.
Which of the following statements accurately describes a solution that fulfills all of these
requirements?
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.)
A cloud consumer is interested in leasing cloud-based virtual servers. It compares the
virtual servers offered by Cloud Provider X and Cloud Provider Y.
Cloud X (owned by Cloud Provider X) and Cloud Y (owned by Cloud Provider Y) both provide shared physical
servers that host multiple virtual servers for other cloud consumers.
The virtual servers on Cloud X are accessed directly, whereas the virtual servers on Cloud
Y are accessed via an automated scaling listener. On Cloud X, virtual servers are pre-
configured to support a specific amount of concurrent cloud service consumers. When this
threshold is exceeded, cloud service consumer requests are rejected. Due to the use of the
automated scaling listener, virtual servers on Cloud Y can provide a greater level of
elasticity.
The hourly cost to the cloud consumer to use a virtual server on Cloud X is half that of the
cost to use a virtual server on Cloud Y.
Within a one month period, Cloud Provider X bases its hourly charge on the maximum number of virtual servers used. Within a one month
period, Cloud Provider Y bases its hourly charges on actual virtual server usage. Cloud
Provider Y charges $20 for each hour that a cloud consumer uses a virtual server.
The cloud consumer predicts its monthly usage requirements to be as follows:
The cloud consumer is required choose the cloud provider with the lowest on-going cost
based on its predicted usage. Which of the following statements accurately calculates the
on-going usage costs of Cloud Providers X and Y and correctly states the cloud provider
that the cloud consumer must choose?
