質問 1: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 X is based on the private cloud deployment model. Cloud Service A is based on
the SaaS delivery model. Cloud Y is based on the public cloud deployment model. Virtual
Server C is being offered as part of the IaaS delivery model. A cloud resource administrator
working for Cloud Consumer Z uses Cloud Service Consumer B to access Virtual Server C.
Cloud Consumer Z' s trust boundary encompasses Cloud Service Consumers A and B,
Cloud Service A and Virtual Server C.
The organization that owns Cloud Consumer Z is the cloud service owner of Cloud Service A.
B. Cloud X is based on the private cloud deployment model. Cloud Service A is based on
the SaaS delivery model. Cloud Y is based on the public cloud deployment model. Virtual
Server C is being offered as part of the IaaS delivery model. A cloud resource administrator
working for Cloud Consumer Z uses Cloud Service Consumer B to access Virtual Server C.
Cloud Consumer Z is the cloud service owner of Cloud Service A.
Cloud Consumer Z's organizational boundary encompasses Cloud Service Consumers A and B.
Cloud Consumer T s trust boundary encompasses Cloud Service Consumers A and B, Cloud
Service A and Virtual Server C.
C. Cloud X is based on the private cloud deployment model. Cloud Service A is based on
the SaaS delivery model. Cloud Y is based on the private cloud deployment model. Virtual
Server C is being offered as part of the IaaS delivery model. A cloud resource administrator
working for Cloud Consumer Z uses Cloud Service Consumer B to access Virtual Server C.
Cloud Consumer Z is the cloud service owner of Cloud Service A.
Cloud Consumer T s organizational boundary encompasses Cloud Service Consumers A and B.
Cloud Consumer T s trust boundary encompasses Cloud Service Consumers A and B, Cloud
Service A and Virtual Server C.
D. Cloud X is based on the private cloud deployment model. Cloud Service A is based on
the SaaS delivery model. Cloud Y is based on the community cloud deployment model.
Virtual Server C is being offered as part of the IaaS delivery model. A cloud resource
administrator working for Cloud Consumer Z uses Cloud Service Consumer A to access
Cloud Service A.
Cloud Consumer T s organizational and trust boundaries encompass
Cloud Service Consumers A and B, Cloud Service A and Virtual Server C.
正解:A
質問 2: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 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 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.
B. 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.
C. 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.
D. 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.
正解:A
